State of the Art: Pouch Surgery in the 21st Century.

BACKGROUND: An ileoanal pouch with IPAA is the preferred method to restore intestinal continuity in patients who require a total proctocolectomy. Pouch surgery has evolved during the past decades thanks to increased experience and research, changes in the medical management of patients who require an ileal pouch, and technological innovations. OBJECTIVE: To review the main changes in pouch surgery over the past 2 decades, with a focus on staging, minimally invasive and transanal approaches, pouch design, and anastomotic configuration. RESULTS: The decision on the staging approach depends on the patient's conditions, their indication for surgery, and the risk of anastomotic leak. A minimally invasive approach should be performed whenever feasible, but open surgery still has a role in this technically demanding operation. Transanal IPAA may be performed in experienced centers and may reduce conversion to open surgery in the hostile pelvis. The J-pouch is the easiest, fastest, and most commonly performed design, but other designs may be used when a J-pouch is not feasible. A stapled anastomosis without mucosectomy can be safely performed in the majority of cases, with a low incidence of rectal cuff neoplasia and better functional outcomes than handsewn. Finally, Crohn's disease is not an absolute contraindication to an ileoanal pouch, but pouch failure may be higher compared to other indications. CONCLUSIONS: Many technical nuances contribute to the success of an ileoanal pouch. The current standard of care is a laparoscopic J-pouch with double-stapled anastomosis, but this should not be seen as a dogma, and the optimal approach and design should be tailored to each patient.

Segmental Colectomy in Ulcerative Colitis.

BACKGROUND: Segmental colectomy in ulcerative colitis is performed in select patients who may be at increased risk for postoperative morbidity. OBJECTIVE: To identify patients with ulcerative colitis who underwent segmental colectomy and assess their postoperative and long-term outcomes. DESIGN: Retrospective case series. SETTING: A tertiary care IBD center. PATIENTS: Patients with ulcerative colitis who underwent surgery between 1995 and 2022. INTERVENTION: Segmental colectomy. MAIN OUTCOME MEASURES: Postoperative complications, early and late colitis, metachronous cancer development, completion proctocolectomy-free survival rates, and stoma at follow-up. RESULTS: Fifty-five patients were included (20 [36.4%] women; age 67.8 (57.4-77.1) years at surgery; BMI 27.7 (24.2-31.1) kg/m 2 ; median follow-up 37.3 months). Thirty-two patients (58.2%) had ASA score of 3, 48 (87.3%) had at least 1 comorbidity, and 48 (87.3%) had Mayo endoscopic subscores of 0 to 1. Patients underwent right hemicolectomy (n = 28; 50.9%), sigmoidectomy (n = 17; 30.9%), left hemicolectomy (6; 10.9%), low anterior resection (n = 2; 3.6%), or a nonanatomic resection (n = 2; 3.6%) for endoscopically unresectable polyps (n = 21; 38.2%), colorectal cancer (n = 15; 27.3%), symptomatic diverticular disease (n = 13; 23.6%), and stricture (n = 6; 10.9%). Postoperative complications occurred in 16 patients (29.1%; n = 7 [12.7%] Clavien-Dindo class III-V). Early and late postoperative colitis rates were 9.1% and 14.5%, respectively. Metachronous cancer developed in 1 patient. Four patients (7.3%) underwent subsequent completion proctocolectomy with ileostomy. Six patients (10.9%) had a stoma at follow-up. Two- and 5-year completion proctocolectomy-free survival rates were 91% and 88%, respectively. LIMITATIONS: Retrospective study and small sample size. CONCLUSIONS: Segmental colectomy in ulcerative colitis is associated with low postoperative complication rates, symptomatic early colitis and late colitis rates, metachronous cancer development, and the need for subsequent completion proctocolectomy. Therefore, it can be safe to consider select patients, such as the elderly with quiescent colitis and other indications, for colectomy. See Video Abstract .

Se produjeron complicaciones postoperatorias en 16 (29,1%) pacientes [7 (12,7%) Clavien-Dindo Clase III-V]. Las tasas de colitis posoperatoria temprana y tardía fueron del 9,1% y el 14,5%, respectivamente. Un paciente desarrolló cáncer metacrónico. A 4 (7,3%) pacientes se les realizó posteriormente proctocolectomía completa con ileostomía. Seis (10,9%) pacientes tenían estoma en el seguimiento. Las tasas de supervivencia sin proctocolectomía completa a dos y cinco años fueron del 91% y 88%, respectivamente.LIMITACIONES:Estudio retrospectivo, tamaño de muestra pequeño.CONCLUSIONES:La colectomía segmentaria en la colitis ulcerosa se asocia con bajas tasas de complicaciones postoperatorias, tasas de colitis sintomática temprana y tasas de colitis tardía, desarrollo de cáncer metacrónico y la necesidad de una posterior proctocolectomía completa. Por lo tanto, puede ser seguro considerar pacientes seleccionados, como los ancianos con colitis inactiva y otras indicaciones de colectomía. (Traducción-Dr. Yolanda Colorado ).

A Propensity Score-Matched Analysis of Single-Port vs. Multi-Port Laparoscopic Total Abdominal Colectomy with End Ileostomy for Medically Refractory Ulcerative Colitis.

BACKGROUND: Medically refractory ulcerative colitis (UC) necessitates surgical intervention, with total abdominal colectomy with end ileostomy being a definitive treatment. The comparison between single-port and multi-port laparoscopic surgery outcomes remains underexplored. OBJECTIVE: To compare the surgical outcomes of single-port versus multi-port laparoscopic surgery in patients undergoing total abdominal colectomy with end ileostomy for medically refractory UC. DESIGN: A retrospective analysis comparing single-port to multi-port surgery in UC patients from 2010 to 2020. Patients were propensity score-matched 3:1 (multi-port to single-port) on baseline characteristics. SETTINGS: Single center academic hospital. MAIN OUTCOME MEASURES: Binary outcomes were compared using a multivariable logistic regression model, and a subset analysis was conducted for postoperative stump leak based on stump implantation during surgery. These metrics were compared between the single-port and multi-port groups to assess the differences in surgical outcomes. RESULTS: The multi-port and single-port groups included 642 and 114 patients, respectively. Matched cohort included 342 multi-ports and 114 single-ports. We observed a statistically significant difference in mean operation time, with the single-port procedure taking 43 minutes less than the multi-port laparoscopy. There were no significant differences between the two groups in postoperative stump leaks, postoperative ileus, stoma site complications, postoperative readmission within 30 days, postoperative reoperation within 30 days, and subsequent IPAA surgery. In the subset analysis, stump implantation was associated with a higher risk of stump leak in the multiport group. The single-port group had a shorter hospital stay. LIMITATIONS: Retrospective nature, being conducted at a single center. CONCLUSION: Single-incision laparoscopic total abdominal colectomy in the treatment of mucosal ulcerative colitis is a safe, effective, and efficient approach. In our cohort, as compared to multi-port approach, single incision laparoscopy has shown shorter operation times and better overall length of stay. Taking into account less invasive approach, decreased abdominal trauma, and faster recovery, single-port surgery is a viable alternative to multi-port surgery. See Video Abstract.

Tofacitinib Is Associated With Increased Risk of Postoperative Venous Thromboembolism in Patients With Ulcerative Colitis.

BACKGROUND: In 2019, the Food and Drug Administration issued a black box warning for increased risk of venous thromboembolism in patients with rheumatoid arthritis exposed to tofacitinib. There are limited data regarding postoperative venous thromboembolism risk in patients with ulcerative colitis exposed to tofacitinib. OBJECTIVE: To assess whether preoperative exposure to tofacitinib is associated with increased odds of postoperative venous thromboembolism. DESIGN: Retrospective review. SETTINGS: Tertiary academic medical center. PATIENTS: Consecutive patients exposed to tofacitinib within 4 weeks before total abdominal colectomy or total proctocolectomy, with or without ileostomy, from 2014 to 2021, matched 1:2 for tofacitinib exposure or no exposure. INTERVENTION: Tofacitinib exposure versus no exposure. MAIN OUTCOME MEASURES: Ninety-day postoperative venous thromboembolism rate. RESULTS: Forty-two patients with tofacitinib exposure and 84 case-matched patients without tofacitinib exposure underwent surgery for medically refractory ulcerative colitis. Nine (22.0%) tofacitinib-exposed patients and 7 (8.5%) unexposed patients were diagnosed with venous thromboembolism within 90 days of surgery. In univariate logistic regression, patients exposed to tofacitinib had 3.01 times increased odds of developing venous thromboembolism within 90 days after surgery compared to unexposed patients ( p = 0.04; 95% CI, 1.03-8.79). Other venous thromboembolism risk factors were not significantly associated with venous thromboembolisms. Venous thromboembolisms in both groups were most commonly portomesenteric vein thromboses (66.7% in the tofacitinib-exposed group and 42.9% in the unexposed group) and were diagnosed at a mean of 23.2 days (range, 3-90 days) postoperatively in the tofacitinib-exposed group and 7.9 days (1-19 days) in the unexposed group. There were no statistically significant differences in location or timing between the 2 groups. LIMITATIONS: Retrospective nature of the study and associated biases. Reliance on clinically diagnosed venous thromboembolisms may underreport the true incidence rate. CONCLUSIONS: Tofacitinib exposure before surgery for medically refractory ulcerative colitis is associated with 3 times increased odds of venous thromboembolism compared with patients without tofacitinib exposure.

TOFACITINIB SE ASOCIA CON UN MAYOR RIESGO DE TROMBOEMBOLISMO VENOSO POSTOPERATORIO EN PACIENTES CON COLITIS ULCEROSA: ANTECEDENTES:En 2019, la FDA emitió una advertencia de recuadro negro sobre un mayor riesgo de tromboembolismo venoso en pacientes con artritis reumatoide expuestos a tofacitinib. Hay datos limitados sobre el riesgo de tromboembolismo venoso postoperatorio en pacientes con colitis ulcerosa expuestos a tofacitinib.OBJETIVO:Evaluar si la exposición preoperatoria a tofacitinib se asocia con mayores probabilidades de tromboembolismo venoso postoperatorio.DISEÑO:Revisión retrospectiva.LUGARES:Centro médico académico terciario.PACIENTES:Pacientes consecutivos expuestos a tofacitinib dentro de las 4 semanas previas a la colectomía abdominal total o proctocolectomía total, con o sin ileostomía, entre 2014 y 2021, emparejados 1:2 para exposición a tofacitinib o ninguna exposición.INTERVENCIÓN(S):Exposición a tofacitinib versus ninguna exposición.PRINCIPALES MEDIDAS DE RESULTADO:Tasa de tromboembolismo venoso posoperatorio a los 90 días.RESULTADOS:Cuarenta y dos pacientes con exposición a tofacitinib y 84 pacientes de casos similares sin exposición a tofacitinib se sometieron a cirugía por colitis ulcerosa médicamente refractaria. Nueve (22,0%) pacientes expuestos a tofacitinib y 7 (8,5%) pacientes no expuestos fueron diagnosticados con tromboembolismo venoso dentro de los 90 días posteriores a la cirugía. En la regresión logística univariada, los pacientes expuestos a tofacitinib tuvieron 3,01 veces más probabilidades de desarrollar un tromboembolismo venoso dentro de los 90 días posteriores a la cirugía en comparación con los no expuestos ( p = 0,04, IC del 95 %: 1,03-8,79). Otros factores de riesgo de tromboembolismo venoso no se asociaron significativamente con el tromboembolismo venoso. Los tromboembolismos venosos en ambos grupos fueron más comúnmente trombosis de la vena portomesentérica (66,7% en los expuestos a tofacitinib y 42,9% en los no expuestos) y se diagnosticaron en una media de 23,2 días (rango, 3-90 días) después de la operación en los expuestos a tofacitinib y 7,9 días. (1-19 días) en los grupos no expuestos, respectivamente. No hubo diferencias estadísticamente significativas en la ubicación o el momento entre los dos grupos.LIMITACIONES:Carácter retrospectivo del estudio y sesgos asociados. La dependencia de tromboembolismos venosos diagnosticados clínicamente puede subestimar la tasa de incidencia real.CONCLUSIONES:La exposición a tofacitinib antes de la cirugía para la colitis ulcerosa médicamente refractaria se asocia con probabilidades 3 veces mayores de tromboembolismo venoso en comparación con los pacientes sin exposición a tofacitinib.

Transanal ileal pouch-anal anastomosis for inflammatory bowel disease: a systematic review and meta-analysis of short-term outcomes.

AIM: Restorative proctocolectomy with transabdominal ileal pouch-anal anastomosis (abd-IPAA) has become the standard surgical treatment for medically refractory ulcerative colitis (UC). However, it requires a technically difficult distal anorectal dissection and anastomosis due to the bony confines of the deep pelvis. To address these challenges, the transanal IPAA approach (ta-IPAA) was developed. This novel approach may offer increased visibility and range of motion compared with abd-IPAA, although its postoperative benefits remain unclear. The aim of this work was to perform a systematic review and meta-analysis to compare and inform the frequency of postoperative outcomes between ta-IPAA and abd-IPAA for patients with UC. METHOD: Several databases were searched from inception until May 2022 for studies reporting postoperative outcomes of patients undergoing ta-IPAA. Reviewers, working independently and in duplicate, evaluated studies for inclusion and graded the risk of bias. Odds ratios (OR), mean differences (MD) and prevalence ratio (PR) and their corresponding 95% confidence intervals (CIs) were calculated using random-effects models. Sensitivity analysis was performed. RESULTS: Ten retrospective studies comprising 284 patients with ta-IPAA were included. Total mesorectal excision was performed in 61.8% of cases and close rectal dissection in 27.9%. There was no difference in the odds of Clavien-Dindo (CD) I-II complications, CD III-IV and anastomotic leak (OR 0.96, 95% CI 0.27-3.40; OR 1.18, 95% CI 0.65-2.16; OR 1.37, 95% CI 0.58-3.23; respectively) between ta-IPAA and abd-IPAA. The ta-IPAA pooled CD I-II complication rate was 18% (95% CI 5%-35%) and for CD III-IV 10% (95% CI 5%-17%), and the anastomotic leak rate was 6% (95% CI 2%-10%). There were no deaths reported. CONCLUSIONS: This meta-analysis compared the novel ta-IPAA procedure with abd-IPAA and found no difference in postoperative outcomes. While the need for randomized controlled trails and comparison of functional outcomes between both approaches remains, this evidence should assist colorectal surgeons to decide if ta-IPAA is a viable alternative.

Acute colonic pseudo-obstruction: a retrospective review of the surgical outcomes.

PURPOSE: Limited data exist regarding the surgical outcomes of acute colonic pseudo-obstruction (ACPO), commonly referred to as Ogilvie syndrome, in modern clinical practice. The prevailing belief is that surgery should be avoided due to previously reported high mortality rates. We aimed to describe the surgical results of ACPO treated within our institution. METHODS: Our prospectively maintained colorectal surgery registry was queried for patients diagnosed with ACPO, who underwent surgery between 2009 and 2022. Postoperative complications were graded according to Clavien-Dindo (CD) classification. The primary outcome was postoperative mortality. RESULTS: A total of 32 patients who underwent surgery for ACPO were identified. Overall, nonoperative therapy was initially administered to 21 patients (65.6%). The surgeries performed included total abdominal colectomy (15, 43.1%), ascending colectomy with end ileostomy (8, 25%), transverse colostomy (5, 15.6%), ileostomy and transverse colostomy (3, 9.4%), and Hartmann's operation (1, 3.1%). Severe postoperative complications (CD grade 3 or 4) occurred in five patients (15.6%). No recurrence of ACPO was observed and no patient required reoperation. The average postoperative length of stay was 14.5 days, 30-day mortality was 6.3% (n = 2), and 90-day mortality was 15.6% (n = 5) due to complications of underlying comorbidities. CONCLUSIONS: Surgical treatment was effective for patients with ACPO refractory to medical therapy or presenting with acute complications. Although postoperative complications were frequent, both the 30- and 90-day mortality rates were lower than previously documented in the literature. Further investigations are warranted to determine the optimal surgical strategy, which may involve total or segmental colectomy, or diversion alone without resection.

Gender Related Differences in Surgeon Compensation: Survey Results from the American Society of Colon and Rectal Surgeons.

OBJECTIVE: We sought to understand the effect of sex on compensation among colorectal surgeons and to determine which factors contribute to gender-based differences in compensation. SUMMARY OF BACKGROUND DATA: The sex-based wage gap in the medical profession is among the most pronounced wage gaps in the U.S. Data regarding the wage gap among colorectal surgeons and the underlying reasons for this disparity remain unclear. METHODS: The Healthcare Economics Committee of the American Society of Colon and Rectal Surgeons conducted a survey to evaluate surgeon demographics, compensation, and practice characteristics. To evaluate the effect of sex on compensation, we performed multivariable linear regression with backward selection. We used a two-sided P -value with a significance threshold <0.05. RESULTS: The mean difference in normalized total compensation between men and women was $46,250, and when salary was adjusted for FTEs, the difference was $57,000. Women were more likely to perform anorectal surgery, less likely to perform general surgery and less likely to hold positions in leadership. After adjustments, women reported significantly lower compensation (aOR, 0.88; 95% CI, 0.80-0.97). Time spent doing abdominal surgery (aOR, 1.13; 95% CI 1.03-1.23), professor status (aOR, 1.17; 95% CI, 1.03-1.32) and instructor status (aOR, 1.49; 95% 1.28-1.73) were independently associated with compensation. CONCLUSIONS: We found a 12% adjusted sex wage gap among colorectal surgeons. Gender-based differences in leadership positions and allocation of effort may contribute. Further research will be necessary to clarify sources of wage inequalities. Still, our results should prompt expedient actions to support closing the gap.

Ileal Pouch-anal Anastomosis in Primary Sclerosing Cholangitis-inflammatory Bowel Disease (PSC-IBD): Long-term Pouch and Liver Transplant Outcomes.

OBJECTIVE: To compare the effect of liver transplantation (LT) on ileal pouch-anal anastomosis (IPAA) outcomes in patients with primary sclerosing cholangitis and inflammatory bowel disease (PSC-IBD). BACKGROUND: Patients with PSC-IBD may require both IPAA for colitis and LT for PSC. METHODS: Patients with PSC-IBD from out institutional pouch registry (1985-2022) were divided according to LT status and timing of LT (before and after IPAA) and their outcomes analyzed. RESULTS: A total of 160 patients were included: 112 (70%) nontransplanted at last follow-up; 48 (30%) transplanted, of which 23 (14%) before IPAA and 25 (16%) after. Nontransplanted patients at IPAA had more laparoscopic procedures [37 (46%) vs 8 (18%), P =0.002] and less blood loss (median 250 vs 400 mL, P =0.006). Morbidity and mortality at 90 days were similar. Chronic pouchitis was higher in transplanted compared with nontransplanted patients [32 (67%) vs 51 (45.5%), P =0.03], but nontransplanted patients had a higher rate of chronic antibiotic refractory pouchitis. Overall survival was similar, but nontransplanted patients had more PSC-related deaths (12.5% vs 2%, P =0.002). Pouch survival at 10 years was 90% for nontransplanted patients and 100% for transplanted patients (log-rank P =0.052). Timing of LT had no impact on chronic pouchitis, pouch failure, or overall survival. PSC recurrence was 6% at 10 years. For transplanted patients, graft survival was similar regardless of IPAA timing. CONCLUSIONS: In patients with PSC-IBD and IPAA, LT is linked to an increased pouchitis rate but does not affect overall and pouch survival. Timing of LT does not influence short-term and long-term pouch outcomes.

Gracilis Flap Repair for Reoperative Rectovaginal Fistula.

BACKGROUND: Surgical treatment of recurrent rectovaginal fistulas is notoriously difficult. Placement of the gracilis muscle between the vagina and anus is an advanced technique used to close persistent fistulas. We have utilized this procedure for recalcitrant fistulas and hypothesized that a gracilis interposition would offer a good treatment option for patients with refractory rectovaginal fistulas, regardless of underlying etiology. OBJECTIVE: The purpose of this study was to investigate healing rates of gracilis interposition in patients with refractory rectovaginal fistulas. DESIGN: Following institutional review board approval, a retrospective review of all adult female patients with a diagnosis of rectovaginal fistula between January 2009 and August 2020 was performed; those who underwent gracilis interposition for definitive fistula closure were included for analysis. SETTINGS: The study was conducted at a colorectal surgery department at a tertiary center in the United States. PATIENTS: All patients were adult females with a diagnosis of a rectovaginal fistula who underwent gracilis interposition for definitive closure. MAIN OUTCOME MEASURES: Patient demographics, etiology of rectovaginal fistula, previous surgical intervention, presence of intestinal diversion, operative details, 30-day morbidity, recurrence of fistula, and time to recurrence. Fistula closure was defined as lack of clinical symptoms following stoma closure, negative fistula detection on gastrograffin enema' and absence of an internal opening at examination under anesthesia. RESULTS: Twenty-two patients were included who had a median age of 43 years (range, 19-64 years) and median body mass index of 31 kg/m 2 (range, 22-51). Median time between prior attempted surgical repair and gracilis surgery was 7 months (range, 3-17). The number of previously attempted repairs were 1-2 (n = 8), 3-4 (n = 9), and > 4 (n = 5). The most recent attempted surgical repair was rectal advancement flap (n = 7), transperineal +/- Martius flap (n = 4), episioproctotomy (n = 3), transvaginal repair (n = 2), and other (n = 6). All patients had fecal diversion at the time of gracilis surgery. Thirty-day postoperative surgical site infection at the graft/donor site was 32% (n = 7). At a median follow-up of 22 months (range 2-62), fistula closure was 59% (n = 13). Gracilis interposition was successful in all inflammatory bowel disease patients. LIMITATIONS: The study was limited by its retrospective nature. CONCLUSIONS: Gracilis interposition is an effective operative technique for reoperative rectovaginal fistula closure. Patients should be counseled regarding the possibility of graft/donor site infection. See Video Abstract at http://links.lww.com/DCR/B763 . REPARACIN CON COLGAJO DE GRACILIS PARA LA FSTULA RECTOVAGINAL REOPERATORIA: ANTECEDENTES:El tratamiento quirúrgico de las fístulas rectovaginales recurrentes es muy difícil.

El cierre de la fístula se definió como la ausencia de síntomas clínicos después del cierre del estoma, la detección negativa de la fístula en el enema de gastrograffin y la ausencia de una abertura interna en el examen bajo anestesia.RESULTADOS:Se incluyeron 22 pacientes que tenían una mediana de edad de 43 años (rango 19-64 años) y una mediana de índice de masa corporal de 31 kg / m2 (rango 22-51). La mediana de tiempo entre el intento previo de reparación quirúrgica y la cirugía del gracilis fue de 7 meses (rango 3-17). El número de reparaciones previamente intentadas fue: 1-2 (n = 8), 3-4 (n = 9), y >4 (n = 5). El intento de reparación quirúrgica más reciente fue el colgajo de avance rectal (n = 7), el colgajo transperineal +/- Martius (n = 4), la episioproctotomía (n = 3), la reparación transvaginal (n = 2) y otros (n = 6). Todos los pacientes tenían derivación fecal en el momento de la cirugía gracilis. La infección del sitio quirúrgico posoperatorio a los 30 días en el sitio del injerto / donante fue del 32% (n = 7). Con una mediana de seguimiento de 22 meses (rango 2-62), el cierre de la fístula fue del 59% (n = 13). La interposición de Gracilis fue exitosa en todos los pacientes con enfermedad inflamatoria intestinal.LIMITACIONES:Carácter retrospectivo de los datos.CONCLUSIONES:La interposición de Gracilis es una técnica quirúrgica eficaz para el cierre reoperatorio de la fístula rectovaginal. Se debe asesorar a los pacientes sobre la posibilidad de infección del sitio del injerto / donante. Consulte Video Resumen en http://links.lww.com/DCR/B763 . (Traducción-Dr. Ingrid Melo ).

Gracilis Muscle Interposition for the Treatment of Rectovaginal Fistula: A Systematic Review and Pooled Analysis.

BACKGROUND: A rectovaginal fistula is a debilitating condition that often severely impacts quality of life. Despite many treatment options available, the best surgical treatment is far from being established, and many patients will undergo several procedures before fistula closure is achieved. Gracilis muscle interposition, which is the transposition of the gracilis muscle into the rectovaginal septum, is an option for complex and persistent fistulas, but literature on the subject is scarce, mainly consisting of small case series. OBJECTIVE: This study aimed to assess the success rate of gracilis muscle interposition for the surgical treatment of rectovaginal fistula. DATA SOURCES: MEDLINE, Embase, Cochrane Library, and Web of Science. STUDY SELECTION: Studies comprising at least 5 patients who underwent gracilis muscle interposition for rectovaginal fistula were included. No date or language restrictions was applied. INTERVENTION: Gracilis muscle interposition. MAIN OUTCOME MEASURES: The primary outcome is the fistula closure rate (%). Other domains analyzed are stoma closure rate, postoperative complications, quality of life, fecal continence, and sexual function. RESULTS: Twenty studies were included for a total of 384 patients. The pooled fistula closure rate for gracilis muscle interposition was 64% (95% CI, 53%-74%; range, 33%-100%). Risk factors for failure were smoking, underlying Crohn's disease, and more than 2 previous repairs, whereas stoma formation was associated with improved outcomes. Postoperative complications ranged from 0% to 37%, mostly related to surgical site occurrences at the harvest site and perineal area. No deaths occurred. Gracilis muscle interposition improved quality of life and fecal continence, but impairment of sexual function was common. LIMITATIONS: Most of the included studies were small case series. CONCLUSIONS: Gracilis muscle interposition is a safe and moderately effective treatment that could be taken into consideration as second- or third-line therapy for recurrent rectovaginal fistula.

Turnbull-Cutait Pull-Through Procedure Is an Alternative to Permanent Ostomy in Patients With Complex Pelvic Fistulas.

BACKGROUND: A permanent stoma is frequently recommended in the setting of complex or recurrent rectovaginal fistulas because of the high failure rate of reconstructive procedures. The Turnbull-Cutait pull-through procedure is a salvage operation for motivated patients desiring to avoid permanent fecal diversion. OBJECTIVE: To analyze the cure rates of complex rectovaginal fistulas after the Turnbull-Cutait pull-through procedure based on cause. DESIGN: After the institutional review approval board, a retrospective review of women who underwent the procedure (1993-2018) for a rectovaginal fistula was conducted. Patients' demographics, cause, and postoperative outcomes were analyzed. SETTING: Colorectal surgery department at a tertiary center in the United States. PATIENTS: Adult women with a rectovaginal fistula who underwent a colonic pull-through procedure were included. MAIN OUTCOME MEASURES: Recurrence after the colonic pull-through procedure. RESULTS: There were 81 patients who underwent colonic pull-through; of those, 26 patients had a rectovaginal fistula, had a median age of 51 (43-57) years, and had a mean BMI of 28 ± 3.2 kg/m 2 . A total of 4 patients (15%) had a recurrence and 85% of the patients healed. Ninety-three percent of the patients healed after the prior anastomotic leak. Patients with a Crohn's disease-related fistula had a 75% cure rate. The Kaplan-Meier analysis showed a cumulative incidence of recurrence of 8% (95% CI, 0%-8%) within 6 months after surgery and 12% at 12 months. LIMITATIONS: Retrospective design. CONCLUSIONS: The Turnbull-Cutait pull-through procedure may be the last option to preserve intestinal continuity and successfully treat rectovaginal fistulas in 85% of cases. EL PROCEDIMIENTO PULLTHROUGH DE TURNBULLCUTAIT ES UNA ALTERNATIVA A LA OSTOMA PERMANENTE EN PACIENTES CON FSTULAS PLVICAS COMPLEJAS: ANTECEDENTES:Con frecuencia se recomienda un estoma permanente en el contexto de una fístula rectovaginal compleja o recurrente debido a la alta tasa de fracaso de los procedimientos reconstructivos. El procedimiento de extracción de Turnbull-Cutait es una operación de rescate para pacientes motivados que desean evitar la desviación fecal permanente.OBJETIVO:Analizar las tasas de curación de la fístula rectovaginal compleja después del procedimiento de extracción de Turnbull-Cutait según la etiología.DISEÑO:Después de la junta de aprobación de revisión institucional, se realizó una revisión retrospectiva de mujeres que se sometieron a un procedimiento (1993-2018) por fístula rectovaginal. Se analizaron los datos demográficos, la etiología y los resultados posoperatorios de los pacientes.AJUSTE:Departamento de cirugía colorrectal en un centro terciario en los Estados Unidos.PACIENTES:Mujeres adultas con fístula rectovaginal que se sometieron a extracción del colon.RESULTADO PRINCIPAL:recurrencia después de la extracción del colon.RESULTADOS:Hubo 81 pacientes que tenían extracción colónica, de esas 26 fístulas rectovaginales con una mediana de edad de 51 (43 - 57) años, y un índice de masa corporal promedio de 28 ± 3,2 kg/m2. Un total de 4 (15%) pacientes tuvieron una recurrencia y el 85% de los pacientes se curaron. El noventa y tres por ciento de los pacientes se curaron después de la fuga anastomótica previa. Los pacientes con fístula relacionada con EC tuvieron una tasa de curación del 75%. El análisis de Kaplan Meier mostró una incidencia acumulada de recurrencia del 8% [95% intervalo de confianza 0%-18%] dentro de los 6 meses posteriores a la cirugía y del 12% a los 12 meses.LIMITACIONES:Diseño retrospectivo.CONCLUSIONES:El procedimiento de extracción de Turnbull-Cutait puede ser la última opción que se puede ofrecer para preservar la continuidad intestinal y tratar la fístula rectovaginal con éxito en el 85% de los casos.

Long-term Outcomes of Perianal Fistulas in Pediatric Crohn's Disease.

BACKGROUND: Approximately 30% of Crohn's disease-related perianal fistulas heal in the adult population with conventional medical and surgical interventions. This healing rate remains unknown in pediatric patients. OBJECTIVE: This study aimed to determine the healing rate of pediatric perianal Crohn's fistulas and identify factors associated with healing. DESIGN: Retrospective case series. SETTING: A quaternary referral center. PATIENTS: Patients aged <18 years with a Crohn's perianal fistula, seen between January 1, 1991, and August 1, 2021, were included in the study. INTERVENTIONS: Multivariable logistic regression to identify factors independently associated with perianal fistula healing. MAIN OUTCOME MEASURES: Healing of Crohn's perianal fistula at the date of last clinical encounter, defined as the clinical note reporting a healed fistula or normal perianal examination. RESULTS: A total of 91 patients aged <18 years with a Crohn's disease-related perianal fistula were identified (59% female, 76% white). The mean (SD) age at Crohn's diagnosis was 12 (±4) years. The mean follow-up after Crohn's diagnosis was 10 (±7) years. Overall, 89% of patients had a perianal fistula, 2% had an anovaginal fistula, and 10% had an ileal pouch-associated fistula. Patients underwent a median (interquartile range) of 2 (1-5) operations. A seton was placed in 60% of patients, 47% underwent abscess drainage, and 44% underwent fistulotomy or fistulectomy. Fistula healing occurred in 71% of patients over a median of 1.3 (0.4-2.5) years. Seven patients (7%) underwent proctectomy, and 3 (3%) underwent ileal pouch excision. After multivariable adjustment, younger age at diagnosis of perianal fistula was associated with an increased likelihood of healing (OR 0.56 for each increased year; 95% CI, 0.34-0.92). LIMITATIONS: Retrospective, single institution. CONCLUSIONS: Over two-thirds of fistulas heal in pediatric Crohn's disease patients with conventional surgical and medical intervention. Younger age at fistula development is associated with an increased likelihood of healing. See Video Abstract at http://links.lww.com/DCR/C185 . RESULTADOS A LARGO PLAZO DE LAS FSTULAS PERIANALES EN LA ENFERMEDAD DE CROHN EN PACIENTES PEDITRICOS: ANTECEDENTES:Aproximadamente el 30% de las fístulas perianales relacionadas con la enfermedad de Crohn se curan en la población adulta con intervenciones médicas y quirúrgicas convencionales.

La edad media (DE) al diagnóstico de Crohn fue de 12 (±4) años. El seguimiento medio tras el diagnóstico de Crohn fue de 10 (±7) años. En general, el 89 % de los pacientes tenía fístula perianal, el 2 % tenía fístula anovaginal y el 10 % de los pacientes tenía fístula asociada a reservorio ileal. Los pacientes fueron sometidos a una mediana (RIC) de 2 (1-5) operaciones. En el 60% de los pacientes se colocó sedal, en el 47% se drenó el absceso y en el 44% se realizó fistulotomía o fistulectomía. La curación de la fístula se produjo en el 71% de los pacientes durante una mediana de 1,3 (0,4-2,5) años. Siete pacientes (7%) se sometieron a proctectomía y 3 (3%) se sometieron a escisión del reservorio ileal. Después del ajuste multivariable, la edad más joven en el momento del diagnóstico de la fístula perianal se asoció con una mayor probabilidad de curación (OR 0,56 por cada año de aumento, IC del 95%, 0,34-0,92).LIMITACIONES:Retrospectivo, institución única.CONCLUSIONES:Más de dos tercios de las fístulas se curan en pacientes pediátricos con enfermedad de Crohn con intervención médica y quirúrgica convencional. Una edad más joven en el momento del desarrollo de la fístula se asocia con una mayor probabilidad de curación. Consulte Video Resumen en http://links.lww.com/DCR/C185 .

Redo Continent Ileostomy in Patients With IBD: Valuable Lessons Learned Over 25 Years.

BACKGROUND: Patients with IBD with continent ileostomies may require revision surgeries. There remains a paucity of data regarding outcomes after redo continent ileostomy. OBJECTIVE: This study aimed to evaluate patient outcomes after redo continent ileostomy. DESIGN: Retrospective cohort study. SETTINGS: This study was conducted at a high-volume, specialized colorectal surgery department. PATIENTS: We identified patients who underwent redo continent ileostomy (defined as neo-pouch construction or major operations changing the pouch configuration) for IBD between 1994 and 2020. MAIN OUTCOME MEASURES: The main outcomes measured were patient demographics, short- and long-term outcomes, and quality of life. RESULTS: A total of 168 patients met inclusion criteria; 102 (61%) were female, the mean age was 51 years (±13.1), and the mean BMI was 24.4 (±3.9). The median time between primary and redo continent ileostomy was 16.8 years. One hundred twenty-two patients (73%) who underwent redo surgery had ulcerative colitis, 36 (21%) had Crohn's disease, and 10 (6%) had indeterminate colitis. Slipped nipple valve and valve stricture were the most common indications for redo continent ileostomy (86%). After a median follow-up of 4 years, 48 patients (29%) required a subsequent reoperation and 27 (16%) had pouch failure requiring pouch excision. The pouch survival rate was 89% at 3 years, 84% at 5 years, and 79% at 10 years. On univariate analysis, a shorter interval between the primary and redo continent ileostomy was associated with long-term pouch failure ( p = 0.003). Cox regression multivariate analysis confirmed that a shorter interval between surgeries was independently associated with pouch failure ( p = 0.014). The mean Cleveland Clinic Global Quality of Life score was 0.61 (± 0.23) among the 70 patients who responded to the questionnaire. LIMITATIONS: The main limitations were that this was a retrospective, single-center study and that it had a low response rate for the Global Quality of Life questionnaire. CONCLUSIONS: Redo continent ileostomy surgery is associated with a long-term pouch retention rate of 79% and satisfactory quality of life. Therefore, redo surgery should be offered to patients who are motivated to keep their continent ileostomy. See Video Abstract at http://links.lww.com/DCR/C87 . REHACER LA ILEOSTOMA CONTINENTE EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL VALIOSAS LECCIONES APRENDIDAS DURANTE AOS: ANTECEDENTES:Los pacientes con enfermedad inflamatoria intestinal con ileostomías continentes pueden requerir cirugías de revisión. Sigue habiendo escasez de datos con respecto a los resultados después de volver a realizar la ileostomía continente.OBJETIVO:Evaluar los resultados después de rehacer la ileostomía continente.DISEÑO:Estudio de cohorte retrospectivo.ESCENARIO:Departamento especializado en cirugía colorrectal de alto volumen.PACIENTES:Identificamos pacientes que se sometieron a una nueva ileostomía continente (definida como construcción de una nueva bolsa u operaciones mayores que cambian la configuración de la bolsa) por enfermedad inflamatoria intestinal entre 1994 y 2020.PRINCIPALES MEDIDAS DE RESULTADO:Datos demográficos de los pacientes, resultados a corto y largo plazo y calidad de vida.RESULTADOS:Un total de 168 pacientes cumplieron con los criterios de inclusión; 102 (61%) eran mujeres, la edad media fue de 51 años (±13,1) y el IMC medio fue de 24,4 (±3,9). La mediana de tiempo entre la ileostomía primaria y la nueva ileostomía continente fue de 16,8 años. Ciento veintidós pacientes (73%) que se sometieron a una nueva cirugía tenían colitis ulcerosa, 36 (21%) tenían enfermedad de Crohn y 10 (6%) tenían colitis indeterminada. El deslizamiento de la válvula del pezón y la estenosis de la válvula fueron las indicaciones más comunes para rehacer la ileostomía continente (86%). Después de una mediana de seguimiento de 4 años, 48 (29%) pacientes requirieron una reintervención posterior y 27 (16%) tuvieron falla de la bolsa que requirió la escisión de la bolsa. La tasa de supervivencia de la bolsa fue del 89 % a los 3 años, del 84% a los 5 años y del 79% a los 10 años. En el análisis univariable, un intervalo de tiempo más corto entre la ileostomía continente primaria y la nueva se asoció con falla de la bolsa a largo plazo (p = 0,003). El análisis multivariable de regresión de Cox confirmó que el intervalo más corto entre cirugías se asoció de forma independiente con el fracaso de la bolsa (p = 0,014). La puntuación media de la Calidad de Vida Global fue de 0,61 (± 0,23) entre los 70 pacientes que respondieron al cuestionario.LIMITACIONES:Estudio retrospectivo de un solo centro. Baja tasa de respuesta al cuestionario de Calidad de Vida.CONCLUSIÓN:La cirugía de ileostomía continente se asocia con una tasa de retención de la bolsa a largo plazo del 79% y una calidad de vida satisfactoria. Por lo tanto, se debe ofrecer una nueva cirugía a los pacientes que están motivados para mantener su ileostomía continente. Consulte Video Resumen en http://links.lww.com/DCR/C87 .

Effect of Incisional Negative Pressure Wound Therapy on Surgical Site Infections in High-Risk Reoperative Colorectal Surgery: A Randomized Controlled Trial.

BACKGROUND: Colorectal resections have relatively high rates of surgical site infections causing significant morbidity. Incisional negative pressure wound therapy was introduced to improve wound healing of closed surgical incisions and to prevent surgical site infections. OBJECTIVE: This randomized controlled trial aimed to investigate the effect of incisional NPWT on superficial surgical site infections in high-risk, open, reoperative colorectal surgery. DESIGN: This was a single-center randomized controlled trial conducted between July 2015-October 2020. Patients were randomly assigned to incisional negative pressure wound therapy or standard gauze dressing with a 1:1 ratio. A total of 298 patients were included. SETTINGS: This study was conducted at the colorectal surgery department of a tertiary-level hospital. PATIENTS: This study included patients older than 18 years who underwent elective reoperative open colorectal resections. Patients were excluded who had open surgery within the past 3 months, who had active surgical site infection, and who underwent laparoscopic procedures. MAIN OUTCOME MEASURES: The primary outcome was superficial surgical site infection within 30 days. Secondary outcomes were deep and organ-space surgical site infections within 7 days and 30 days, postoperative complications, and length of hospital stay. RESULTS: A total of 149 patients were included in each arm. The mean age was 51 years, and 49.5% were women. Demographics, preoperative comorbidities, and preoperative albumin levels were comparable between the groups. Overall, most surgeries were performed for IBD, and 77% of the patients had an ostomy fashioned during the surgery. No significant difference was found between the groups in 30-day superficial surgical site infection rate (14.1% in control versus 9.4% in incisional negative pressure wound therapy; p = 0.28). Deep and organ-space surgical site infections rates at 7 and 30 days were also comparable between the groups. Postoperative length of stay and complication rates (Clavien-Dindo grade) were also comparable between the groups. LIMITATIONS: The patient population included in the trial consisted of a selected group of high-risk patients. CONCLUSIONS: Incisional negative pressure wound therapy was not associated with reduced superficial surgical site infection or overall complication rates in patients undergoing high-risk reoperative colorectal resections.

Does the age of ulcerative colitis diagnosis impact outcomes of restorative proctocolectomy?

BACKGROUND: Ulcerative colitis (UC) can be diagnosed at a variety of different ages. We evaluated if age of ulcerative colitis (UC) diagnosis impacts outcomes of restorative proctocolectomy (RP) with ileal pouch-anal anastomosis (IPAA). METHODS: A prospectively maintained pouch database (1983-2020) was queried to identify patients undergoing an RP for UC. The cohort was stratified based on bimodal disease presentation into 2 groups: the early adulthood group (19-30 years old) and the mid/late adulthood group (40-70 years old). Patients' demographics, postoperative complications, functional (stool number, seepage), and quality of life (QoL) rates were compared between the groups. RESULTS: A total of 628 patients with an age range of 19-30 years old (18.1 ± 2.2 at the time of diagnosis, 24.2 ± 10.5 at the time of IPAA) and 706 patients with an age range of 40-70 years old (45 ± 3.0 at time of diagnosis, 52.3 ± 9.4 at time of IPAA) were identified. Older patients had longer disease duration, higher BMI, lower biologic use, and greater one-/two-staged IPAA, with 20% hand sewn anastomosis and 16.5% of S pouch configuration compared to younger ones. No difference was observed in anastomotic separation, pelvic sepsis, fistulas, or pouch failure in follow-up. Postoperatively, older patients more frequently developed bowel obstructions, strictures, and pouchitis, in addition to higher rates of seepage (p < 0.05). QoL was comparable between groups. CONCLUSION: While IPAA retention rates are comparable between different age cohorts, older age at diagnosis and IPAA construction is associated with higher rates of pouchitis, bowel obstruction, anastomotic strictures, and worse functional outcome. Quality of life is similar in those who retain their ileal pouch on the long-term.

Assessing prognostic factors of long-term survival after surgery for colorectal gastrointestinal stromal tumours.

AIM: Due to their rarity, the management of colorectal gastrointestinal stromal tumours (CR GISTs) is still under debate. The aim of this study was to assess prognostic factors. METHOD: We performed a retrospective review of patients who underwent surgery with curative intent for CR GIST at our centre from 2002 to 2019. Factors associated with overall (OS) and recurrence-free survival (RFS) were analysed. RESULTS: Fifty-six patients were included [median age 63 years, 29 (52%) female, 30 (54%) Miettinen high-risk, 40 (71%) with rectal GIST]. Nineteen (34%) patients received perioperative (neoadjuvant and/or adjuvant) imatinib. All cases of colonic GIST had an R0 resection, compared with 28 (70%) of rectal GISTs. After a median follow-up of 97 months (interquartile range 48-155 months), 14 (25%) deaths and 14 (25%) recurrences occurred. In the high-risk cohort, factors associated with improved RFS were R0 resection (OR 0.19, 95% CI 0.1-0.5, p = 0.002) and perioperative imatinib (OR 0.33, 95% CI 0.42-0.97, p = 0.04). Patients who had received perioperative imatinib had longer RFS (60% vs. 11% at 5 years, p = 0.006) but not OS. In rectal GISTs, 5-year OS was 85% for R0 and 70% for R1 resections (p = 0.164) and 5-year RFS was 85% for R0 and 12% for R1 resection (p < 0.001). When stratifying patients by perioperative imatinib, there were no differences in OS or RFS in the R0 or R1 groups. CONCLUSION: Perioperative imatinib and R0 resection were associated with improved RFS in high-risk patients with CR GIST. In patients with rectal GIST, R1 resection was associated with worse RFS irrespective of perioperative imatinib treatment.

Construction of J- and S-Pouches.

BACKGROUND: Pelvic pouch surgery evolved under the late Dr. Victor Fazio's influence. OBJECTIVE: This article aimed to describe construction of J- and S-pouches according to Fazio's teachings. TECHNICAL POINTS: There are several key points to consider for pelvic pouch construction, starting with the decision of performing a 2- or 3-stage procedure and handling of the rectal stump. At time of pouch construction, ileal reach must be assessed early in the operative course, and mesenteric lengthening maneuvers are deployed as warranted. If these maneuvers still do not allow sufficient length, alternatives include an S-pouch, longer rectal stump/anal transitional zone, or returning to the operating room at a later date. The rectum is then mobilized sufficiently to allow a straight stapler firing to avoid outlet obstruction from impinged nearby tissues. The 15- to 20-cm pouch is constructed, ensuring that its staple lines are straight, staple line bleeding is addressed, the tip of the J is closed to be as short as possible, and a leak test is performed. At the time of the anastomosis, it is crucial to keep the mesentery and pouch straight, ensure no bowel is trapped below the mesentery, confirm that anterior structures are not being incorporated into the anastomosis, and perform a leak test, adding transanal sutures as needed to repair any defects. An ileostomy is then created. CONCLUSION: Pouch construction is challenging. At each stage, consider the patient, who carries the ultimate risk. The end goal is a functional, long-lasting pouch.

Small Bowel Crohn's Disease Recurrence is Common After Total Proctocolectomy for Crohn's Colitis.

BACKGROUND: Surgical intervention for Crohn's disease involving the colon is often a total proctocolectomy with end ileostomy. There are limited data regarding postoperative small bowel recurrence rates in the recent era. OBJECTIVE: The purpose of this study was to determine the rate of small bowel Crohn's disease recurrence following total proctocolectomy and secondarily define risk factors for disease recurrence. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at four hospitals within a single healthcare system. PATIENTS: Patients were those with Crohn's disease undergoing total proctocolectomy with end ileostomy between 2009-2019. MAIN OUTCOME MEASURES: Main outcome measures were clinical, endoscopic, radiographic, and/or surgical Crohn's disease recurrence. RESULTS: In total, 193 patients were included with a median follow-up of 1.8 years (IQR 0.4-4.6). Overall, 74.6% (n = 144) of patients had been previously exposed to biologic therapy, and 51.3% (n = 99) had a history of small bowel Crohn's disease. Postoperatively, 14.5% (n = 28) of patients received biologic therapy. Crohn's disease recurrence occurred in 23.3% (n = 45) of patients with an estimated median 5-year recurrence rate of 40.8% (95% CI' 30.2-51.4). Surgical recurrence occurred in 8.8% (n = 17) of patients with an estimated median 5-year recurrence rate of 16.9% (95% CI' 8.5-25.3). On multivariable analysis, prior small bowel surgery for Crohn's disease (HR 2.61; 95% CI' 1.42-4.81) and Crohn's diagnosis at age <18 years (HR 2.56; 95% CI' 1.40-4.71) were associated with Crohn's recurrence. In patients without prior small bowel Crohn's disease, 14.9% (n = 14) had Crohn's recurrence with an estimated 5-year overall recurrence rate of 31.1% (95% CI' 13.3-45.3) and 5-year surgical recurrence rate of 5.7% (95% CI' 0.0-12.0). LIMITATIONS: The study was limited by its retrospective design and lack of consistent follow-up on all patients. CONCLUSIONS: Greater than one third of patients who underwent total proctocolectomy for Crohn's disease were estimated to have small bowel Crohn's recurrence at 5 years after surgery. Patients with a history of small bowel surgery for Crohn's and diagnosis at any early age may benefit from more intensive postoperative surveillance and consideration for early medical prophylaxis.

RECURRENCIA FRECUENTE DE LA ENFERMEDAD DE CROHN DEL INTESTINO DELGADO DESPUS DE LA PROCTOCOLECTOMA TOTAL POR COLITIS DE CROHN: ANTECEDENTES:La cirugia para la enfermedad de Crohn que involucra el colon es a menudo una proctocolectomía total con ileostomía terminal. Hay datos limitados con respecto a las tasas de recurrencia posoperatoria de la enfermedad de Crohn del intestino delgado en la actualidad.OBJETIVO:Buscamos determinar la tasa de recurrencia de la enfermedad de Crohn del intestino delgado después de la proctocolectomía total y, en segundo lugar, definir los factores de riesgo de recurrencia de la enfermedad.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLINICO:Cuatro hospitales de un mismo sistema sanitario.PACIENTES:Pacientes con enfermedad de Crohn sometidos a proctocolectomía total con ileostomía terminal entre 2009-2019.PRINCIPALES MEDIDAS DE VALORACIÓN:Recurrencia clínica, endoscópica, radiográfica y / o quirúrgica de la enfermedad de Crohn.RESULTADOS:Se incluyeron 193 pacientes con un seguimiento promedio de 1,8 años (IQR 0,4-4,6). El 74,6% (n = 144) de los pacientes habían recibido previamente terapia biológica y el 51,3% (n = 99) tenían antecedentes de enfermedad de Crohn del intestino delgado. Después de la operación, el 14,5% (n = 28) de los pacientes recibieron terapia biológica. La recurrencia de la enfermedad de Crohn ocurrió en el 23,3% (n = 45) de los pacientes con una tasa de recurrencia media estimada a los 5 años del 40,8% (IC del 95%: 30,2-51,4). La recidiva quirúrgica se produjo en el 8,8% (n = 17) de los pacientes con una tasa de recidiva media estimada a los 5 años del 16,9% (IC del 95%: 8,5-25,3). En el análisis multivariable, la cirugía previa del intestino delgado para la enfermedad de Crohn (HR 2,61, IC del 95%: 1,42-4,81) y el diagnóstico de Crohn a la edad <18 (HR 2,56, IC del 95%: 1,40-4,71) se asociaron con la recurrencia de Crohn. En pacientes sin enfermedad previa de Crohn del intestino delgado, el 14,9% (n = 14) tuvo recurrencia de Crohn con una tasa de recurrencia general estimada a 5 años del 31,1% (IC del 95%: 13,3-45,3) y una tasa de recurrencia quirúrgica a 5 años del 5,7% (IC del 95%: 0,0-12,0).LIMITACIONES:Diseño retrospectivo, falta de seguimiento constante de todos los pacientes.CONCLUSIONES:Se estimó que más de un tercio de los pacientes que se sometieron a proctocolectomía total tenían recurrencia de Crohn del intestino delgado a los 5 años después de la cirugía. Los pacientes con antecedentes de cirugía por enfermedad de Crohn del intestino delgado y diagnóstico a una edad temprana pueden beneficiarse de una vigilancia posoperatoria más intensiva y la consideración de una profilaxis médica temprana.

Diverting Loop Ileostomy in the Management of Medically Refractory Constipation Cases Not Falling Into Classical Categories.

BACKGROUND: The approach to constipation refractory to medical management does not necessarily follow classical teaching and is challenging. Although the role of surgery is unclear, diverting loop ileostomy may be offered to gauge symptom response followed by colectomy for appropriate patients. OBJECTIVE: Our goal was to examine outcomes in patients with constipation not falling into classical subtypes who underwent diverting loop ileostomy creation as the initial surgical intervention. Our secondary aim was to offer patients colectomy and anastomosis and examine their outcome if they improved after ileostomy. DESIGN: The study design was a retrospective review. SETTINGS: This study was conducted in the pelvic floor center of our colorectal surgery department from January 2006 to December 2018. PATIENTS: Patients with medically refractory constipation referred for surgical consideration and not falling into classical constipation categories (slow transit, normal transit, or pelvic floor dysfunction) underwent evaluation with transit marker study, cinedefecography, and anal physiology and were offered ileostomy as initial surgical management. MAIN OUTCOME MEASURES: The primary measures were symptom improvement and self-reported quality of life improvement with increased patient satisfaction. RESULTS: Eighty-seven patients underwent diverting loop ileostomy as initial surgical therapy. Group 1 had 54 (62%) patients who self-reported symptom improvement, discontinued anticonstipation medication, and had ileostomy output >200 mL/day. Of these 54 patients, 25 had colectomy with anastomosis, 16 (64%) of whom had symptom improvement, stayed off bowel medication, and had >1 bowel movement daily. Group 2 had 33 patients who did not meet the above criteria after initial ileostomy. Nine patients in group 2 elected colectomy with anastomosis after intensive counseling; 6 (66%) reported the same positive results above. LIMITATIONS: The study limitations included: 1) no objective outcome measures of patient's perceived symptom improvement and satisfaction and 2) retrospective review. CONCLUSION: Initial creation of diverting loop ileostomy may be offered to a subset of refractory constipation patients not falling into classical categories after thorough workup. Patients who self-report symptom improvement, have ileostomy output >200 mL/day, and do not require bowel medication may have acceptable results with subsequent colectomy and ileorectal anastomosis.

ILEOSTOMA EN ASA DERIVATIVA EN CASOS DE ESTREIMIENTO REFRACTARIOS AL TRATAMIENTO MDICO, QUE NO PERTENECEN A LAS CATEGORAS CLSICAS: ANTECEDENTES:El enfoque del estreñimiento refractario al tratamiento médico, que no siempre se presenta como las formas descritas clasicamente, es un desafío. Si bien el papel de la cirugía no está claro, se puede ofrecer una ileostomía en asa para medir la respuesta de los síntomas, seguida de colectomía en pacientes seleccionados.OBJETIVO:Evaluar los resultados de pacientes con estreñimiento, que no pertenecen a las formas clásicas de presentación, que se les realizó una ileostomía en asa de derivación, como intervención quirúrgica inicial. El objetivo secundario fue ofrecer a los pacientes una colectomía con anastomosis primaria y evaluar si mejoraban sus resultados después de la ileostomía.DISEÑO:El diseño del estudio fue una revisión retrospectiva.MARCO:Este estudio se realizó en el centro del piso pélvico de nuestro departamento de cirugía colorrectal, e incluyo los pacientes atendidos entre enero de 2006 y diciembre de 2018.PACIENTES:Se incluyeron los pacientes con estreñimiento refractario al tratamiento médico, derivados para evaluación quirúrgica, que no presentaban las formas clásicas de presentación (tránsito lento, tránsito normal, disfunción del suelo pélvico). Estos se sometieron a evaluación con estudio de tránsito colónico, cinedefecografía y fisiología anal, y se les ofreció una ileostomía en asa como tratamiento quirúrgico inicial.PRINCIPALES MEDIDAS DE RESULTADO:Las primeras medidas fueron la mejora de los síntomas y la calidad de vida informado por el paciente.RESULTADOS:Ochenta y siete pacientes fueron sometidos a ileostomía en asa como tratamiento quirúrgico inicial. El grupo 1 tenía 54 (62%) pacientes que informaron mejoría de los síntomas, interrumpieron la medicación proquinética y tuvieron un débito por la ileostomía >200 cc/día. De estos 54 pacientes, 25 se sometieron a colectomía más anastomosis primaria y 16 (64%) tuvieron una mejoría de los síntomas, dejaron de tomar medicamentos proquinéticos y tuvieron más de una evacuación al día. El grupo 2 tenía 33 pacientes que no cumplían con los criterios de mejoría de los síntomas después de la ileostomía inicial. Nueve pacientes del grupo 2 eligieron colectomía con anastomosis después de un asesoramiento intensivo, 6 (66%) informaron resultados positivos de mejoría de los síntomas.LIMITACIONES:Las limitaciones del estudio incluyeron 1) ninguna medida de resultado objetiva de la mejora y satisfacción de los síntomas percibidos por el paciente 2) revisión retrospectiva.CONCLUSIÓNES:La creación inicial de una ileostomía en asa de derivación se puede ofrecer a un subgrupo de pacientes con estreñimiento refractario que no entran en las categorías clásicas después de un estudio exhaustivo. La mejoría de los síntomas, informado por los pacientes, producción de ileostomía >200 cc/día y que no requieren medicación proquinética, pueden tener resultados aceptables con colectomía y anastomosis ileorrectal.

Short- and Long-term Outcomes of Ileal Pouch Anal Anastomosis Construction in Obese Patients With Ulcerative Colitis.

BACKGROUND: Obese patients are traditionally considered difficult pouch candidates because of the potential for intraoperative technical difficulty and increased postoperative complications. OBJECTIVE: The purpose of this study was to compare the outcomes of obese versus nonobese patients with ulcerative colitis undergoing an IPAA. DESIGN: This is a retrospectively, propensity score-matched, prospectively collected cohort study. SETTING: This study was conducted at an IBD quaternary referral center. PATIENTS: Patients with ulcerative colitis undergoing IPAA (1990-2018) were included. Obesity was defined as a BMI ≥30 kg/m 2 . MAIN OUTCOME MEASURES: The primary measures included 30-day complications, long-term anastomotic leak, and pouch failure rate (excision, permanent diversion, revision). RESULTS: Of 3300 patients, 631 (19.1%) were obese (median BMI = 32.4 kg/m 2 ). On univariate analysis, obese patients were more likely to be >50 years old (32.5% versus 22.7%, p < 0.001), ASA class 3 (41.7% versus 27.7%, p < 0.001), have diabetes (8.1% versus 3.3%, p < 0.001), and have had surgery in the biologic era (72.4% versus 66.2%, p = 0.003); they were less likely to have received preoperative steroids (31.2% versus 37.4%, p = 0.004). After a median follow-up of 7 years, 66.7% had completed at least 1 quality-of-life survey. Pouch survival in the matched sample was 99.2% (99.8% nonobese versus 95.4% obese, p = 0.002). After matching and controlling for confounding variables, worse clinical outcomes associated with obesity included global quality of life (relative risk, -0.71; p = 0.002) and long-term pouch failure (HR, 4.24; p = 0.007). Obesity was also independently associated with an additional 27 minutes of operating time ( p < 0.001). There was no association of obesity with the likelihood of developing a postoperative complication, length of stay, or pouch leak. CONCLUSION: Restorative ileoanal pouch surgery in obese patients with ulcerative colitis is associated with a relatively decreased quality of life and increased risk of long-term pouch failure compared with nonobese patients. Obese patients may benefit from focused counseling about these risks before undergoing restorative pouch surgery. See Video Abstract at http://links.lww.com/DCR/B873 . RESULTADOS A CORTO Y LARGO PLAZO EN LA REALIZACIN DEL RESERVORIO ILEAL EN PACIENTES OBESOS CON COLITIS ULCEROSA: ANTECEDENTES:Habitualmente se considera a los obesos como pacientes difíciles para la realización de un reservorio ileal, debido a su alta probabilidad de presentar dificultades técnicas intraoperatoria y aumento de las complicaciones posoperatorias.OBJETIVO:El propósito de este estudio fue comparar los resultados de pacientes con colitis ulcerosa obesos versus no obesos sometidos a un reservorio ileal y anastomosis anal (IPAA).DISEÑO:Este es un estudio de cohorte recopilado prospectivamente, retrospectivo, emparejado por puntajes de propensión.AJUSTE:Este estudio se llevó a cabo en un centro de referencia de cuarto nivel para enfermedades inflamatorias del intestino.PACIENTES:Se incluyeron pacientes con colitis ulcerosa sometidos a un reservorio ileal y anastomosis anal (1990-2018). Obesidad definida como un IMC ≥ 30 kg/m2.PRINCIPALES RESULTADO MEDIDOS:Los principales resultados medidos incluyeron complicaciones a los 30 días, fuga anastomótica a largo plazo y tasa de falla del reservorio ileal (escisión, derivación permanente, revisión).RESULTADOS:De 3.300 pacientes, 631 (19,1%) eran obesos (mediana de IMC = 32,4 kg/m2). En el análisis univariado, los pacientes obesos tenían más probabilidades de ser > 50 años (32,5% frente a 22,7%, p < 0,001), clase ASA 3 (41,7% frente a 27,7%, p < 0,001), tener diabetes (8,1% frente a 3,3%, p < 0,001), haberse sometido a cirugía en la era biológica (72,4% frente a 66,2%, p = 0,003), y tenían menos probabilidades de haber recibido esteroides preoperatorios (31,2% frente a 37,4%, p = 0,004). Después de una mediana de seguimiento de 7 años, el 66,7% había completado al menos una encuesta de calidad de vida. La supervivencia de la bolsa en la muestra emparejada fue del 99,2% (99,8% no obesos versus 95,4% obesos, p = 0,002). Después de emparejar y controlar las variables de confusión, los peores resultados clínicos asociados con la obesidad incluyeron la calidad de vida global (RR = -0,71, p = 0,002) y el fracaso de la bolsa a largo plazo (HR = 4,24, p = 0,007). La obesidad también se asoció de forma independiente con 27 minutos adicionales de tiempo quirúrgico ( p < 0,001). No hubo asociación de la obesidad con la probabilidad de desarrollar una complicación posoperatoria, la duración de la estadía o la fuga de la bolsa.CONCLUSIÓNES:La cirugía restauradora del reservorio ileoanal en pacientes obesos con colitis ulcerosa se asocia a una disminución relativa de la calidad de vida y un mayor riesgo de falla del reservorio a largo plazo en comparación con los pacientes no obesos. Los pacientes obesos pueden beneficiarse de un asesoramiento centrado en estos riesgos antes de someterse a una cirugía restauradoracon reservorio ileal y anastomosis anal.
