Functional Outcomes After Transanal Total Mesorectal Excision (taTME) for Rectal Cancer: Results From the Phase II North American Multicenter Prospective Observational Trial.

OBJECTIVE: To investigate fecal incontinence and defecatory, urinary, and sexual functional outcomes after transanal total mesorectal excision (taTME). BACKGROUND: Proctectomy for rectal cancer may result in alterations in defecatory, urinary, and sexual function that persist beyond 12 months. The recent multicenter phase II taTME trial demonstrated the safety of taTME in patients with stage I to III tumors. METHODS: Prospectively registered self-reported questionnaires were collected from 100 taTME patients. Fecal continence [Fecal Incontinence Quality of Life (FIQL), Wexner], defecatory function [Colorectal Functional Outcome (COREFO)], urinary function (International Prostate Symptom Score), and sexual function (Female Sexual Function Index-female, International Index of Erectile Function-male) were assessed preoperatively (PQ), 3 to 4 months postileostomy closure (FQ1), and 12 to 18 months post-taTME [postoperative questionnaire 2 (FQ2)]. RESULTS: Among 83 patients who responded at all 3 time points, FIQL, Wexner, and COREFO significantly worsened postileostomy closure. Between FQ1 and FQ2, FIQL lifestyle and coping, Wexner, and COREFO incontinence, social impact, frequency, and need for medication significantly improved, while FIQL depression and embarrassment did not change. International Prostate Symptom Score did not change relative to preoperative scores. For females, Female Sexual Function Index declined for desire, orgasm, and satisfaction between PQ and FQ1, and did not improve between FQ1 and FQ2. In males, International Index of Erectile Function declined with no change between FQ1 and FQ2. CONCLUSIONS: Although taTME resulted in initial decline in defecatory function and fecal continence, most functional domains improved by 12 months after ileostomy closure, without returning to preoperative status. Urinary function was preserved while sexual function declined without improvement by 18 months post-taTME. Our results address patient expectations and inform shared decision-making regarding taTME.

Tofacitinib Exposure Does Not Increase Postoperative Complications Among Patients With Ulcerative Colitis Undergoing Total Colectomy: A Retrospective Case-Control Study.

BACKGROUND: Ulcerative colitis, total colectomy, and tofacitinib have all been associated with an increased risk of venous thromboembolism. OBJECTIVE: To determine whether preoperative tofacitinib exposure increases venous thromboembolism or other postoperative complications among patients with ulcerative colitis undergoing subtotal colectomy, total colectomy, or total proctocolectomy. DESIGN: Retrospective, case-controlled study at a single institution. SETTINGS: A tertiary referral center. PATIENTS: Adult patients with ulcerative colitis undergoing subtotal colectomy, total colectomy, or total proctocolectomy after 2018 who were taking tofacitinib within 30 days of surgery (n = 56) were compared to age- and sex-matched patients with ulcerative colitis undergoing the same surgeries but who were not exposed to tofacitinib (n = 56). MAIN OUTCOME MEASURE: The primary outcome was differences in the incidence of venous thromboembolism within 90 days of surgery based on tofacitinib exposure. Secondary outcomes were 90-day postoperative complications. RESULTS: Groups were well matched for age (non-tofacitinib: mean 35.2 years [SD 12.0], tofacitinib: 35.9 [SD 12.1], p = 0.36) and sex (41% women in each group, p = 1.00). Medical characteristics were similar between groups except for biological medication exposure 30 days before surgery (non-tofacitinib: 66%, tofacitinib: 36%, p = 0.004). Surgical characteristics did not differ between groups. Most patients were discharged on extended venous thromboembolism prophylaxis (non-tofacitinib: 80% and tofacitinib: 77%). Adjusted for biological exposure, there were no statistically significant differences in venous thromboembolism (non-tofacitinib exposed: 14%, tofacitinib exposed: 4%, p = 0.09) or other postoperative outcomes. LIMITATION: Retrospective, single institutional study. CONCLUSIONS: Among patients with ulcerative colitis undergoing total colectomy or proctocolectomy, exposure to tofacitinib was not associated with an increased risk of venous thromboembolism or other postoperative complications.

Los resultados secundarios fueron las complicaciones posoperatorias a los 90 días.RESULTADOS:Los grupos se encontraban bien emparejados por edad (sin tofacitinib: media 35,2 años [DE 12,0], tofacitinib: 35,9 [DE 12,1], p = 0,36) y sexo (41% mujeres en cada grupo, p = 1,00). Las características médicas fueron similares entre los grupos, excepto por la exposición a medicamentos biológicos 30 días antes de la cirugía (sin tofacitinib: 66 %, tofacitinib: 36 %, p = 0,004). Las características quirúrgicas no difirieron entre los grupos. La mayoría de los pacientes fueron dados de alta con profilaxis extendida para tromboembolismo venoso (sin tofacitinib: 80% y tofacitinib: 77%). Ajustado a la exposición biológica, no hubo diferencias estadísticamente significativas en el tromboembolismo venoso (no expuestos a tofacitinib: 14%, expuestos a tofacitinib: 4%, p = 0,09) u otros resultados posoperatorios.LIMITACIÓN:Estudio institucional único, retrospectivo.CONCLUSIÓN:Entre los pacientes con colitis ulcerosa sometidos a colectomía total o proctocolectomía, la exposición a tofacitinib no se asoció con un mayor riesgo de tromboembolismo venoso u otras complicaciones posoperatorias.

Navigating Progress: 8-Year Single-Center Experience With Minimally Invasive Proctectomy and IPAA.

BACKGROUND: IPAA has become the criterion standard for treating ulcerative colitis, familial adenomatous polyposis, and selected cases of Crohn's colitis. Robotic surgery promises improved postoperative outcomes and decreased length of stay. However, few studies have evaluated the benefits of robotic IPAA compared to laparoscopy. OBJECTIVE: To compare short-term 30-day postoperative outcomes of robotic versus laparoscopic proctectomy with IPAA and diverting loop ileostomy. DESIGN: Retrospective observational study from a single, high-volume center. SETTINGS: Mayo Clinic, Rochester, Minnesota (tertiary referral center for IBD). PATIENTS: All adult patients undergoing minimally invasive proctectomy with IPAA and diverting loop ileostomy between January 2015 and April 2023. MAIN OUTCOME MEASURES: Thirty-day complications, hospital length of stay, estimated blood loss, conversion rate, 30-day readmission, and 30-day reoperation. RESULTS: Two hundred seventeen patients were included in the study; 107 underwent robotic proctectomy with IPAA and diverting loop ileostomy, whereas 110 had laparoscopic proctectomy with IPAA and diverting loop ileostomy. Operating time was significantly longer in the robotic group (263 ± 38 vs 228 ± 75 minutes, p < 0.0001). The robotic group also had lower estimated blood loss (81.5 ± 77.7 vs 126.8 ± 111.0 mL, p = 0.0006) as well as fewer conversions (0% vs 8.2%, p = 0.003). Patients in the robotic group received more intraoperative fluids (3099 ± 1140 vs 2472 ± 996 mL, p = 0.0001). However, there was no difference in length of stay, 30-day morbidity, 30-day readmission, 30-day reoperation, rate of diverting loop ileostomy closure at 3 months, and surgical IPAA complication rate after ileostomy closure. LIMITATIONS: Retrospective design, single-center study, potential bias because of the novelty of the robotic approach, and lack of long-term and quality-of-life outcomes. CONCLUSIONS: Robotic proctectomy with IPAA and diverting loop ileostomy may offer advantages in terms of estimated blood loss and conversion rate while maintaining the benefits of minimally invasive surgery. Further research is needed to evaluate long-term outcomes. See Video Abstract .

Sin embargo, pocos estudios han evaluado los beneficios de la IPAA robótica en comparación con la laparoscopia.OBJETIVO:Comparar los resultados postoperatorios a corto plazo a 30 días de la proctectomía robótica versus laparoscópica con IPAA e ileostomía en asa de derivación.DISEÑO:Estudio observacional retrospectivo de un único centro de gran volumen.AJUSTES:Mayo Clinic, Rochester, Minnesota (centro terciario de referencia para EII).PACIENTES:Todos los pacientes adultos sometidos a proctectomía mínimamente invasiva con IPAA y DLI entre Enero de 2015 y Abril de 2023.PRINCIPALES MEDIDAS DE RESULTADOS:Complicaciones a los 30 días, duración de la estancia hospitalaria, pérdida de sangre estimada, tasa de conversión, reingreso a los 30 días y reoperación a los 30 días.RESULTADOS:Se incluyeron en el estudio 217 pacientes; 107 se sometieron a proctectomía robótica con IPAA y DLI, mientras que 110 se sometieron a proctectomía laparoscópica con IPAA y DLI. El tiempo operatorio fue significativamente mayor en el grupo robótico (263 ± 38 minutos versus 228 ± 75 minutos, p < 0,0001); la pérdida de sangre estimada (EBL) fue menor en el grupo robótico (81,5 ± 77,7 ml versus 126,8 ± 111,0 ml, p = 0,0006), así como el número de conversiones (0% versus 8,2%, p = 0,003). Los pacientes del grupo robótico recibieron más líquidos intraoperatorios (3099 ± 1140 ml versus 2472 ± 996 ml, p = 0,0001). Sin embargo, no hubo diferencias en la duración de la estancia hospitalaria, la morbilidad a los 30 días, el reingreso a los 30 días, la reoperación a los 30 días, la tasa de cierre del DLI a los tres meses y la tasa de complicaciones quirúrgicas de la IPAA después del cierre de la ileostomía.LIMITACIONES:Diseño retrospectivo, estudio unicéntrico, posible sesgo debido a la novedad del enfoque robótico, falta de resultados a largo plazo y de calidad de vida.CONCLUSIONES:La proctectomía robótica con IPAA y DLI puede ofrecer ventajas en términos de EBL y tasa de conversión, manteniendo al mismo tiempo los beneficios de la cirugía mínimamente invasiva. Se necesita más investigación para evaluar los resultados a largo plazo. (Traducción-Dr. Yesenia Rojas-Khalil ).

Surgical management of duodenal crohn's disease.

BACKGROUND: Operative options for duodenal Crohn's disease include bypass, stricturoplasty, or resection. What factors are associated with operation selection and whether differences exist in outcomes is unknown. METHODS: Patients with duodenal Crohn's disease requiring operative intervention across a multi-state health system were identified. Patient and operative characteristics, short-term surgical outcomes, and the need for future endoscopic or surgical management of duodenal Crohn's disease were analyzed. RESULTS: 40 patients underwent bypass (n = 26), stricturoplasty (n = 8), or resection (n = 6). Median age of diagnosis of Crohn's disease was 23.5 years, and over half of the patients had undergone prior surgery for CD. Operation type varied by the most proximal extent of duodenal involvement. Patients with proximal duodenal CD underwent bypass operations more commonly than those with mid- or distal duodenal disease (p = 0.03). Patients who underwent duodenal stricturoplasty more often required concomitant operations for other sites of small bowel or colonic CD (63%) compared to those who underwent bypass (39%) or resection (33%). No patients required subsequent surgery for duodenal CD at a median follow-up of 2.8 years, but two patients required endoscopic dilation (n = 1 after stricturoplasty, n = 1 after resection). CONCLUSION: Patients who require surgery for duodenal Crohn's disease appear to have an aggressive Crohn's disease phenotype, represented by a younger age of diagnosis and a high rate of prior resection for Crohn's disease. Choice of operation varied by proximal extent of duodenal Crohn's disease.

Robotic-assisted reoperative ileal pouch-anal anastomosis: robotic pouch excision and pouch revision.

BACKGROUND: Up to 20% of patients with ileal pouch will develop pouch failure, ultimately requiring surgical reintervention. As a result of the complexity of reoperative pouch surgery, minimally invasive approaches were rarely utilized. In this series, we present the outcomes of the patients who underwent robotic-assisted pouch revision or excision to assess its feasibility and short-term results. METHODS: All the patients affected by inflammatory bowel diseases and familial adenomatous polyposis who underwent robotic reoperative surgery of an existing ileal pouch were included. RESULTS: Twenty-two patients were included; 54.6% were female. The average age at reoperation was 51 ± 16 years, with a mean body mass index of 26.1 ± 5.6 kg/m2. Fourteen (63.7%) had a diagnosis of ulcerative colitis at reoperation, and seven (31.8%) had Crohn's disease. The mean time to pouch reoperation was 12.8 ± 11.8 years. Seventeen (77.3%) patients underwent pouch excision, and five (22.7%) had pouch revision surgery. The mean operative time was 372 ± 131 min, and the estimated blood loss was 199 ± 196.7 ml. The conversion rate was 9.1%, the 30-day morbidity rate was 27.3% (with only one complication reaching Clavien-Dindo grade IIIB), and the mean length of stay was 5.8 ± 3.9 days. The readmission rate was 18.2%, the reoperation rate was 4.6%, and mortality was nihil. All patients in the pouch revisional group are stoma-free. CONCLUSION: Robotic reoperative pouch surgery in highly selected patients is technically feasible with acceptable outcomes.

Discordance in Total Mesorectal Excision Specimen Grading in a Prospective Phase 2 Multicenter Rectal Cancer Trial: Are We Overestimating the Quality of Our Resections?

OBJECTIVES: To report the results of a rigorous quality control (QC) process in the grading of total mesorectal excision (TME) specimens during a multicenter prospective phase 2 trial of transanal TME. BACKGROUND: Grading of TME specimens is based on the macroscopic assessment of the mesorectum and standardized through synoptic pathology reporting. TME grade is a strong predictor of outcomes with incomplete (IC) TME associated with increased rates of local recurrence relative to complete or near complete (NC) TME. Although TME grade serves as an endpoint in most rectal cancer trials, in protocols incorporating centralized review of TME specimens for quality assurance, discordance in grading and the management thereof has not been previously described. METHODS: A phase 2 prospective transanal TME trial was conducted from 2017 to 2022 across 11 North American centers with TME quality as the primary study endpoint. QC measures included (1) training of site pathologists in TME protocols, (2) blinded grading of de-identified TME specimen photographs by central pathologists, and (3) reconciliation of major discordance before trial reporting. Cohen Kappa statistic was used to assess agreement in grading. RESULTS: Overall agreement in grading of 100 TME specimens between site and central reviewer was rated as fair, (κ = 0.35; 95% CI: 0.10-0.61; P < 0.0001). Concordance was noted in 54%, with minor and major discordance in 32% and 14% of cases, respectively. Upon reconciliation, 13/14 (93%) major discordances were resolved. Pre versus postreconciliation rates of complete or NC and IC TME are 77%/16% and 7% versus 69%/21% and 10%. Reconciliation resulted in a major upgrade (IC-NC; N = 1) or major downgrade (NC/C-IC, N = 4) in 5 cases overall (5%). CONCLUSIONS: A 14% rate of major discordance was observed in TME grading between the site and central reviewers. The resolution resulted in a major change in final TME grade in 5% of cases, which suggests that reported rates or TME completeness are likely overestimated in trials. QC through a central review of TME photographs and reconciliation of major discordances is strongly recommended.

Multicenter phase II trial of transanal total mesorectal excision for rectal cancer: preliminary results.

BACKGROUND: Transanal TME (taTME) combines abdominal and transanal dissection to facilitate sphincter preservation in patients with low rectal tumors. Few phase II/III trials report long-term oncologic and functional results. We report early results from a North American prospective multicenter phase II trial of taTME (NCT03144765). METHODS: 100 patients with stage I-III rectal adenocarcinoma located ≤ 10 cm from the anal verge (AV) were enrolled across 11 centers. Primary and secondary endpoints were TME quality, pathologic outcomes, 30-day and 90-day outcomes, and stoma closure rate. Univariable regression analysis was performed to assess risk factors for incomplete TME and anastomotic complications. RESULTS: Between September 2017 and April 2022, 70 males and 30 females with median age of 58 (IQR 49-62) years and BMI 27.8 (IQR 23.9-31.8) kg/m2 underwent 2-team taTME for tumors located a median 5.8 (IQR 4.5-7.0) cm from the AV. Neoadjuvant radiotherapy was completed in 69%. Intersphincteric resection was performed in 36% and all patients were diverted. Intraoperative complications occurred in 8% including 3 organ injuries, 2 abdominal and 1 transanal conversion. The 30-day and 90-day morbidity rates were 49% (Clavien-Dindo (CD) ≥ 3 in 28.6%) and 56% (CD ≥ 3 in 30.4% including 1 mortality), respectively. Anastomotic complications were reported in 18% including 10% diagnosed within 30 days. Higher anastomotic risk was noted among males (p = 0.05). At a median follow-up of 5 (IQR 3.1-7.4) months, 98% of stomas were closed. TME grade was complete or near complete in 90%, with positive margins in 2 cases (3%). Risk factors for incomplete TME were ASA ≥ 3 (p = 0.01), increased time between NRT and surgery (p = 0.03), and higher operative blood loss (p = 0.003). CONCLUSION: When performed at expert centers, 2-team taTME in patients with low rectal tumors is safe with low conversion rates and high stoma closure rate. Mid-term results will further evaluate oncologic and functional outcomes.

Incisional hernia rates between intracorporeal and extracorporeal anastomosis in minimally invasive ileocolic resection for Crohn's disease.

PURPOSE: One-third of patients with Crohn's disease (CD) require multiple surgeries during their lifetime. So, reducing the incisional hernia rate is crucial. We aimed to define incisional hernia rates after minimally invasive ileocolic resection for CD, comparing intracorporeal anastomosis with Pfannenstiel incision (ICA-P) versus extracorporeal anastomosis with midline vertical incision (ECA-M). METHODS: This retrospective cohort compares ICA-P versus ECA-M from a prospectively maintained database of consecutive minimally invasive ileocolic resections for CD performed between 2014 and 2021 in a referral center. RESULTS: Of the 249 patients included: 59 were in the ICA-P group, 190 in the ECA-M group. Both groups were similar according to baseline and preoperative characteristics. Overall, 22 (8.8%) patients developed an imaging-proven incisional hernia: seven at the port-site and 15 at the extraction-site. All 15 extraction-site incisional hernias were midline vertical incisions [7.9%; p = 0.025], and 8 patients (53%) required surgical repair. Time-to-event analysis showed a 20% rate of extraction-site incisional hernia in the ECA-M group after 48 months (p = 0.037). The length of stay was lower in the intracorporeal anastomosis with Pfannenstiel incision group [ICA-P: 3.3 ± 2.5 vs. ECA-M: 4.1 ± 2.4 days; p = 0.02] with similar 30-day postoperative complication [11(18.6) vs. 59(31.1); p = 0.064] and readmission rates [7(11.9) vs. 18(9.5); p = 0.59]. CONCLUSION: Patients in the ICA-P group did not encounter any incisional hernias while having shorter hospital length of stay and similar 30-day postoperative complications or readmission compared to ECA-M. Therefore, more consideration should be given to performing intracorporeal anastomosis with Pfannenstiel incision during Ileocolic resection in patients with CD to reduce hernia risk.

Minimally invasive vs. open approach to the simultaneous treatment of colorectal tumors with synchronous liver metastasis: a single center, propensity-score matched analysis from Mayo clinic.

BACKGROUND: Open combined resections of colorectal primary tumors and synchronous liver metastases have become common in selected cases. However, evidences favoring a minimally invasive (MIS) approach are still limited. The aim of this study is to evaluate the outcomes of MIS vs. open synchronous liver and colorectal resections. METHODS: 384 cases of synchronous colorectal and liver resections performed at one institution were identified during the study period. MIS vs open approach were compared after a propensity score matching; surgical outcomes were analyzed. RESULTS: MIS cases featured longer operative time (399 vs 300 min, p < 0.001), fewer blood loss (200 vs 500 ml, p = 0.003), and shorter hospitalization (median LOS 4 vs 6 days, p = 0.001). No difference was observed between the two groups for use of Pringle maneuver (p = 0.083), intraoperative blood transfusion (p = 0.061), achievement of negative colorectal (p = 0.176) and liver margins (p = 1.000), postoperative complications (p = 1.000) and significant (Clavien-Dindo ≥ 3a) complications (p = 0.817), delay of adjuvant therapy due to complications (p = 0.555), 30- and 90-day mortality. CONCLUSION: Synchronous colorectal and liver metastases resections via a minimally-invasive approach in high-volume centers with appropriate expertise result in significantly lower blood loss and length of stay despite longer operative time in comparison to open, with no oncological inferiority.

Intraoperative Fluid Management a Modifiable Risk Factor for Surgical Quality - Improving Standardized Practice.

OBJECTIVE: We aimed to determine a safe zone of intraoperative fluid management associated with the lowest postoperative complication rates without increased acute kidney injury (AKi) risk for elective colorectal surgery patients. BACKGROUND: To date, standard practice within institutions, let alone national expectations related to fluid administration, are limited. This fact has perpetuated a quality gap. METHODS: Elective colorectal surgeries between 2018 and 2020 were included. Unadjusted odds ratios (ORs) for postoperative ileus, prolonged LOS, and AKi were plotted against the rate of intraoperative RL infusion (mL/ kg/h) and total intraoperative volume. Binary logistic regression analysis, including fluid volumes as a confounder, was used to identify risk factors for postoperative complications. RESULTS: A total of 2900 patients were identified. Of them, 503 (17.3%) patients had ileus, 772 (26.6%) patients had prolonged LOS, and 240 (8.3%) patients had AKI. The intraoperative fluid resuscitation rate (mg/kg/h) was less impactful on postoperative ileus, LOS, and AKI than the total amount of intraoperative fluid. A total fluid administration range between 300 mL and 2.7 L was associated with the lowest complication rate. Total intraoperative RL ≥2.7 L was independently associated with a higher risk of ileus (adjusted OR 1.465; 95% confidence interval 1.154-1.858) and prolonged LOS (adjusted OR 1.300; 95% confidence interval 1.047-1.613), but not AKI. Intraoperative RL ≤300 mL was not associated with an increased risk of AKI. CONCLUSION: Total intraoperative RL ≥2.7 L was independently associated with postoperative ileus and prolonged LOS in elective colorectal surgery patients. A new potential standard for intraoperative fluids will require anesthesia case planning (complexity and duration) to ensure total fluid volume meets this new opportunity to improve care.

Turnbull-Cutait abdominoperineal pull-through operation: The Cleveland Clinic experience in the 21st century.

AIM: The Turnbull-Cutait pull-through procedure (TCO) restores intestinal continuity in the setting of chronic pelvic sepsis, colorectal anastomotic leak, complex pelvic fistulas and technical challenges related to complicated rectal cancer. The aim of this study was to evaluate the outcomes of the TCO for salvaging complex pelvic conditions and to compare it to hand-sewn immediate coloanal anastomosis (CAA). METHODS: This is a retrospective single-institution study where we searched a prospectively maintained database to identify patients who underwent the TCO. Patient demographics, operative indications and outcomes were analysed. TCO success was defined as maintenance of intestinal continuity and being stoma-free. Kaplan-Meier analysis was employed for stoma-free survival analysis. RESULTS: A total of 81 patients with TCO and 129 patients with CAA were included. The TCO success rate was 69% at a median of 1.4 years' follow-up with 25 (31%) patients ending up with a permanent stoma compared to 22 (17%) in the CAA group with a median follow-up of 4 years (P = 0.03). The Kaplan-Meier cumulative incidence of TCO success at 1, 3 and 5 years was 79%, 60% and 51%, respectively, compared to 91%, 81% and 73% after CAA. CONCLUSION: The TCO has a high success rate for patients with complex pelvic conditions who may be facing a permanent stoma as their only option.

Rethinking postoperative care: same-day ileostomy closure discharge improves patient outcomes.

BACKGROUND: The evolution of enhanced recovery pathways (ERPs) in colon and rectal surgery has led to the development of same-day discharge (SDD) procedures for selected patients. Early discharge after diverting loop ileostomy (DLI) closure was first described in 2003. However, its widespread adoption remains limited, with SDD accounting for only 3.2% of all DLI closures in 2005-2006, according to the American College of Surgeons National Surgical Quality Improvement Program database, and rising to just 4.1% by 2016. This study aimed to compare the outcomes of SDD DLI closure with those of DLI closure after the standard ERP. METHODS: A retrospective case-matched study compared 125 patients undergoing SDD DLI closure with 250 patients undergoing DLI closure after the standard ERP based on age (±1 year), sex, American Society of Anesthesiologists score, body mass index, surgery date (±2 months), underlying disease, and hospital site. The primary outcome was comparative 30-day complication rates. RESULTS: Patients in the traditional ERP group received more intraoperative fluids (1221.1 ± 416.6 vs 1039.0 ± 368.3 mL, P < .001) but had similar estimated blood loss. Ten patients (8%) in the SDD-ERP group failed SDD. The 30-day postoperative complication rate was significantly lower in the SDD group (14.8%) than the standard ERP group (25.7%, P = .025). This difference was primarily driven by a lower incidence of ileus in the SDD group (9.6% vs 14.8%, P = .034). There were no significant differences in readmission rate (9.6% of SDD-ERP vs 9.2% of standard ERP, P = .900) and reoperation rates (3.2% of SDD-ERP vs 2.4% of standard ERP, P = .650). CONCLUSION: SDD ileostomy closure is a safe, feasible, and effective procedure associated with fewer complications than the present study's standard ERP. This could represent a new standard of care. Further prospective trials are required to confirm the findings of this study.

Evolution of laparoscopic ileal pouch-anal anastomosis: impact of enhanced recovery program, medication changes, and staged approaches on outcomes.

BACKGROUND: Although laparoscopic Ileal pouch-anal anastomosis (IPAA) has become the gold standard in restorative proctocolectomy, surgical techniques have experienced minimal changes. In contrast, substantial shifts in perioperative care, marked by the enhanced recovery program (ERP), modifications in steroid use, and a shift to a 3-staged approach, have taken center stage. METHODS: Data extracted from our prospective IPAA database focused on the first 100 laparoscopic IPAA cases (historic group) and the latest 100 cases (modern group), aiming to measure the effect of these evolutions on postoperative outcomes. RESULTS: The historic IPAA group had more 2-staged procedures (92% proctocolectomy), whereas the modern group had a higher number of 3-staged procedures (86% proctectomy) (P < .001). Compared with patients in the modern group, patients in the historic group were more likely to be on steroids (5% vs 67%, respectively; P < .001) or immunomodulators (0% vs 31%, respectively; P < .001) at surgery. Compared with the historic group, the modern group had a shorter operative time (335.5 ± 78.4 vs 233.8 ± 81.6, respectively; P < .001) and length of stay (LOS; 5.4 ± 3.1 vs 4.2 ± 1.6 days, respectively; P < .001). Compared with the modern group, the historic group exhibited a higher 30-day morbidity rate (20% vs 33%, respectively; P = .04) and an elevated 30-day readmission rate (9% vs 21%, respectively; P = .02). Preoperative steroids use increased complications (odds ratio [OR], 3.4; P = .01), whereas 3-staged IPAA reduced complications (OR, 0.3; P = .03). ERP was identified as a factor that predicted shorter stays. CONCLUSION: Although ERP effectively reduced the LOS in IPAA surgery, it failed to reduce complications. Conversely, adopting a 3-staged IPAA approach proved beneficial in reducing morbidity, whereas preoperative steroid use increased complications.

Continent ileostomies: what the radiologist needs to know.

Continent ileostomies are performed in patients who are not candidates for or do not want a traditional J-pouch after total colectomy. In these cases, patients may opt for a type of continent ileostomy instead of an end ileostomy. The most common types of continent ileostomies include the Kock (K) pouch, S-pouch and Barnett Continent Intestinal Reservoir. The normal fluoroscopic and CT appearance of these types of continent ileostomies are reviewed. CT provides better evaluation of the proximal small bowel and pouch for inflammatory bowel disease, while fluoroscopy is superior in evaluating the nipple valve. Common complications of these types of continent ileostomies are discussed including slipped nipple valve, pouch inflammation, fistulas, and polyps. Radiologist should be familiar with the different types of continent ileostomies that exist and their common complications.

Atypical presentation of a rare disorder; idiopathic myointimal hyperplasia of mesenteric veins (IMHMV): Report of two cases.

INTRODUCTION: Idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) is a rare type of chronic colonic ischemia. Patients commonly present with progressive abdominal pain, bloody diarrhea, and weight loss. IMHMV is a common mimicker of inflammatory bowel disease. However, medical management does not have a primary role and curative treatment is surgical resection. PRESENTATION OF CASE: We report two cases of IMHMV with atypical presentation. The first is an 82-year-old male who had refractory, painless, explosive, and non-bloody diarrhea initially treated with antidiarrheal medications and dietary changes to no effect. Colonoscopy was not clarifying. However, CT scan had characteristic findings of IMHMV. He underwent partial colectomy and recovered well. The second case is a 59-year-old male who had recurrent episodes of sudden, massive diarrhea. He was initially treated for diverticulitis based on colonoscopy findings but did not experience relief. Eventually, MRI of the abdomen was suggestive of IMHMV. He underwent surgical resection, which confirmed the diagnosis of IMHMV. He was treated for Clostridioides difficile diarrhea five months after surgery and pulmonary embolism seven months after surgery. With over a year of follow up, neither has had disease recurrence. DISCUSSION: Diagnosis and treatment of rare disorders like IMHMV is challenging, especially when they mimic common entities or present in atypical ways. CONCLUSION: We present two cases to highlight IMHMV as part of the differential for colitis-like symptoms. These cases demonstrate the importance of diagnostic imaging in diagnosis. Diagnostic uncertainty can lead to exposure to ineffective medical treatments and delay in curative surgery.

Risk factors for surgical site infections and trends in skin closure technique after diverting loop ileostomy reversal: A multi-institutional analysis.

BACKGROUND: Surgical site infections (SSIs) are one of the most common complications following diverting loop ileostomy (DLI) closures. This study assesses SSIs after DLI closure and the temporal trends in skin closure technique. METHODS: A retrospective review was conducted using the American College of Surgeons National Surgical Quality Improvement Program database for adult patients who underwent a DLI closure between 2012 and 2021 across a multistate health system. Skin closure technique was categorized as primary, primary â€‹+ â€‹drain, or purse-string closure. The primary outcome was SSI at the former DLI site. RESULTS: A SSI was diagnosed in 5.7% of patients; 6.9% for primary closure, 5.7% for primary closure â€‹+ â€‹drain, and 2.7% for purse-string closure (p â€‹= â€‹0.25). A diagnosis of Crohn's disease, diverticular disease, and increasing operative time were significant risk factors for SSIs. There was a positive trend in the use of purse-string closure over time (p â€‹< â€‹0.0001). CONCLUSIONS: This study identified a low SSI rate after DLI closure which did not vary significantly based on skin closure technique. Utilization of purse-string closure increased over time.

Rectal cancer pelvic recurrence: imaging patterns and key concepts to guide treatment planning.

For rectal cancer, MRI plays an important role in assessing extramural tumor spread and informs surgical planning. The contemporary standardized management of rectal cancer with total mesorectal excision guided by imaging-based risk stratification has dramatically improved patient outcomes. Colonoscopy and CT are utilized in surveillance after surgery to detect intraluminal and extramural recurrence, respectively; however, local recurrence of rectal cancer remains a challenge because postoperative changes such as fat necrosis and fibrosis can resemble tumor recurrence; additionally, mucinous adenocarcinoma recurrence may mimic fluid collection or abscess on CT. MRI and 18F-FDG PET are problem-resolving modalities for equivocal imaging findings on CT. Treatment options for recurrent rectal cancer include pelvic exenteration to achieve radical (R0 resection) resection and intraoperative radiation therapy. After pathologic diagnosis of recurrence, imaging plays an essential role for evaluating the feasibility and approach of salvage surgery. Patterns of recurrence can be divided into axial/central, anterior, lateral, and posterior. Some lateral and posterior recurrence patterns especially in patients with neurogenic pain are associated with perineural invasion. Cross-sectional imaging, especially MRI and 18F-FDG PET, permit direct visualization of perineural spread, and contribute to determining the extent of resection. Multidisciplinary discussion is essential for treatment planning of locally recurrent rectal cancer. This review article illustrates surveillance strategy after initial surgery, imaging patterns of rectal cancer recurrence based on anatomic classification, highlights imaging findings of perineural spread on each modality, and discusses how resectability and contemporary surgical approaches are determined based on imaging findings.

Colectomy for patients with super obesity: current practice and surgical morbidity in the United States.

BACKGROUND: While minimally invasive surgery contributed to improved outcomes in bariatric surgery, less is known about current utilization trends and outcomes related to surgical technique for colorectal resections in super-obese patients (body mass index ≥50 kg/m2). OBJECTIVE: The aim of this study was to compare surgical modalities and short-term outcomes of patients with super obesity who underwent elective colectomy in the United States. SETTING: A retrospective review was performed of patients with super obesity who underwent elective colectomy between 2012 to 2018 using the American College of Surgeons National Quality Improvement Program data pool. METHODS: Patients were categorized into an open, laparoscopic, or robotic group. Baseline characteristics and perioperative outcomes including 30-day complications and length of stay were compared between the 3 groups. Furthermore, utilization trends of surgical modalities were assessed. RESULTS: Of 1199 patients, 338 (28.2%) had open, 735 (61.3%) laparoscopic, and 126 (10.5%) robotic colectomy during the study period, primarily for colon cancer (50.8%). Patients in the open group tended to have more baseline co-morbidities. Laparoscopic approach showed better risk-adjusted outcomes compared with open for postoperative ileus (adjusted odds ratio [aOR]: .6, 95% confidence interval [CI; .383-.965]), overall medical complications (aOR: .4, 95%CI [.3-.8]), and length of stay (OR .6, 95% CI [.394-.968]). Trend utilization showed increasing utilization of the robotic platform over the study period, which was associated with less unplanned conversion to open (aOR .417, 95%CI [.199-.872]). CONCLUSION: Laparoscopic colectomy provides advantageous outcomes over open surgery for colectomy in super-obese patients. The robotic platform has been increasingly used over time, and potential benefits need to be further studied.
