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. La colocación del músculo gracilis entre la vagina y el ano es una técnica avanzada que se utiliza para cerrar las fístulas persistentes. Hemos utilizado este procedimiento para las fístulas recalcitrantes y planteamos la hipótesis de que una interposición del gracilis ofrecería una buena opción de tratamiento para pacientes con fístulas rectovaginales refractarias, independientemente de la etiología subyacente.OBJETIVO:Investigar las tasas de curación de la interposición del gracilis en pacientes con fístulas rectovaginales refractarias.DISEÑO:Tras la aprobación de la junta de revisión institucional, se realizó una revisión retrospectiva de todas las pacientes adultas con un diagnóstico de fístula rectovaginal entre enero de 2009 y agosto de 2020; los que se sometieron a interposición de gracilis para el cierre definitivo de la fístula se incluyeron para el análisis.AJUSTE:Departamento de cirugía colorrectal de un centro terciario en Estados Unidos.PACIENTES:Todas las pacientes adultas con diagnóstico de fístula rectovaginal que se sometieron a interposición de gracilis para cierre definitivo.PRINCIPALES MEDIDAS DE RESULTADO:datos demográficos del paciente, etiología de la fístula rectovaginal, intervención quirúrgica previa, presencia de derivación intestinal, detalles quirúrgicos, morbilidad a los 30 días, recurrencia de la fístula y tiempo hasta la recurrencia. 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 ).

The Learning Curve for Advanced Endoscopy for Colorectal Lesions: A Surgeon's Experience at a High-Volume Center.

BACKGROUND: Advanced endoscopy can be used for the complete removal of large colorectal polyps. To date, few surgeons perform advanced endoscopy, and it is unknown how many procedures are needed to reach proficiency. OBJECTIVE: This study aimed to determine the learning curve for colorectal advanced endoscopy. DESIGN: Retrospective. SETTING: Tertiary referral center. PATIENTS: We queried a prospectively maintained institutional database of advanced endoscopy performed by a high-volume colorectal surgeon between 2011 and 2018. MAIN OUTCOME MEASURES: Advanced endoscopy characteristics were compared for 6 chronological intervals. Primary end points were the rates of complications and polyp recurrence. Secondary end point was the change in polyp removal rate (mm/h) over time. RESULTS: A total of 207 patients underwent advanced endoscopy for a single colorectal polyp. The median polyp size was 30 (4-70) mm, 61.5% were located in the right colon, and 8.8% were malignant. The mean procedure time was 77 (range, 16-320) minutes. Immediate colon resection occurred in 25 patients because of suspicion of cancer or concern for perforation and was excluded from the learning curve analysis. The remaining 182 advanced endoscopy procedures were divided into intervals of 30 procedures. The median removal rate was highest in the last interval and in the endoscopy suite. A removal rate of 30 mm/h was achieved after performing 100 cases. The complication rate (bleeding or return to operating room) was 12.1% and was similar across intervals. The readmission rate was 11.5%, and 6.6% of 6-month follow-up colonoscopies showed polyp recurrence at the resection site. LIMITATIONS: Retrospective design and single surgeon. CONCLUSION: The learning curve for achieving proficiency with advanced endoscopy in the colon and rectum required a minimum of 100 cases with a low complication rate, low polyp recurrence rate, high en bloc resection rate, and a polyp removal rate of 30 mm/h.

Hasta la fecha, pocos cirujanos realizan endoscopia avanzada y se desconoce cuántos procedimientos se necesitan para alcanzar la competencia.OBJETIVO:Determinar la curva de aprendizaje de la endoscopia colorrectal avanzada.DISEÑO:Retrospectivo.AJUSTE:Centro de referencia terciario.PACIENTES:Consultamos una base de datos institucional mantenida prospectivamente de endoscopia avanzada realizada por un cirujano colorrectal de alto volumen entre 2011 y 2018.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las características de la endoscopia avanzada en seis intervalos cronológicos. Los puntos finales primarios fueron las tasas de complicaciones y recurrencia de pólipos. El criterio de valoración secundario fue el cambio en la tasa de eliminación de pólipos (mm/h) a lo largo del tiempo.RESULTADOS:Un total de 207 pacientes se sometieron a una endoscopia avanzada por un solo pólipo colorrectal. La mediana del tamaño de los pólipos fue de 30 (4-70) mm, el 61,5% se ubicaron en el colon derecho y el 8,8% fueron malignos. El tiempo medio del procedimiento fue de 77 (rango: 16-320) minutos. La resección inmediata del colon ocurrió en 25 pacientes debido a la sospecha de cáncer o preocupación por la perforación y fueron excluidos del análisis de la curva de aprendizaje. Los restantes 182 procedimientos de endoscopia avanzada se dividieron en intervalos de 30 procedimientos. La mediana de la tasa de extirpación fue más alta en el último intervalo y en la sala de endoscopia. Se logró una tasa de extirpación de 30 mm/hr después de realizar 100 casos. La tasa de complicaciones (sangrado o retorno al quirófano) fue del 12,1% y fue similar en todos los intervalos. La tasa de reingreso fue del 11,5% y el 6,6% de las colonoscopias de seguimiento a los 6 meses mostraron recurrencia de pólipos en el sitio de la resección.LIMITACIONES:Diseño retrospectivo, cirujano único.CONCLUSIÓN:La curva de aprendizaje para lograr el dominio de la endoscopia avanzada en el colon y el recto requiere un mínimo de 100 casos con una baja tasa de complicaciones, baja tasa de recurrencia de pólipos, alta tasa de resección en bloque y una tasa de eliminación de pólipos de 30 mm/h.

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.

What are the outcomes in patients referred to a tertiary referral centre for Crohn's rectovaginal fistula surgery?

AIM: Rectovaginal fistulas in patients with Crohn's disease are challenging to manage, and surgical treatment remains the best option for achieving permanent closure of the fistula. Biologicals are now used routinely for patients with Crohn's disease. The aim of this study was to investigate the surgical procedures used by us to treat rectovaginal fistula in patients with Crohn's disease in the era of biologicals. METHOD: Patients with Crohn's disease who underwent surgery for a rectovaginal fistula between 2010 and 2020 were included in this retrospective study and were identified from a prospectively maintained institutional database. Collected variables included demographics, perioperative and operative variables and data regarding medications used. Success of the procedure was defined as no symptoms at least 6 months after definitive repair and/or stoma closure. RESULTS: Twenty patients (out of 80 referred for evaluation) underwent surgery with intent to close the fistula and had at least 6 months of follow-up. Mean age was 44 ± 12 years with a median follow-up duration of 33 months (range 6-130 months). Forty per cent of the patients had a history of at least two surgeries to close the fistula. The overall healing rate was 70% (14/20). The most performed procedure was a transanal rectal advancement flap (7/20), with a success rate of 85%. CONCLUSION: Rectovaginal fistula in Crohn's disease is difficult to cure; according to our results almost half of these patients have multiple surgeries due to recurrence. Multiple procedures may be offered for this challenging problem in motivated patients. Perioperative diversion should be strongly considered.

Do surface morphology and pit pattern have a role in predicting cancer for colon polyps in North America?

BACKGROUND: The surface morphology of colorectal polyps is well correlated with submucosal invasion in Eastern Countries but not in North America. We aimed to investigate associations between the Paris classification, surface morphology, and Kudo pit pattern to submucosal invasion in advanced endoscopic resection techniques. METHODS: We retrospectively analyzed prospectively collected data of consecutive advanced endoscopic procedures conducted by a single surgeon between August 2017 and October 2018. The data included patients' demographics, the endoscopic finding of polyps (Paris, Kudo, and surface morphology), and pathology results. RESULTS: The study consisted of 138 lesions, and the mean age was 67 ± 10 years. The most common polyp locations were cecum (n = 41, 30%) followed by ascending colon (n = 28, 20%), and sigmoid colon (n = 18, 13%).The median polyp size was 30 mm (25-40). The en-bloc resection rate was 96%, and 11 (8%) polyps had adenocarcinoma with submucosal invasion. Nine patients (6.5%) had late bleeding, and 3 (2.2%) perforation occurred. Polyps with pit pattern of Kudo IV (n = 4, 36.4%) and Kudo V (n = 6, 54.5%) were associated with submucosal invasion. CONCLUSIONS: Surface morphology and pit pattern can predict submucosal invasion in the North American patient population. Polyp morphology may aid polyp selection for advanced endoscopic interventions.

Risk Factors Associated With Postoperative Mortality Among COVID-19 Positive Patients: Results of 3027 Operations and Procedures.

OBJECTIVE: To investigate the predictors of postoperative mortality in coronavirus disease 2019 (COVID-19)-positive patients. BACKGROUND: COVID-19-positive patients have more postoperative complications. Studies investigating the risk factors for postoperative mortality in COVID-19-positive patients are limited. METHODS: COVID-19-positive patients who underwent surgeries/procedures in Cleveland Clinic between January 2020 and March 2021 were identified retrospectively. The primary outcome was postoperative/procedural 30-day mortality. Secondary outcomes were length of stay, intensive care unit admission, and 30-day readmission. RESULTS: A total of 2543 patients who underwent 3027 surgeries/procedures were included. Total 48.5% of the patients were male. The mean age was 57.8 (18.3) years. A total of 71.2% had at least 1 comorbidity. Total 78.7% of the cases were elective. The median operative time was 94 (47.0-162) minutes and mean length of stay was 6.43 (13.4) days. Postoperative/procedural mortality rate was 4.01%. Increased age [odds ratio (OR): 1.66, 95% CI, 1.4-1.98; P <0.001], being a current smoker [2.76, (1.3-5.82); P =0.008], presence of comorbidity [3.22, (1.03-10.03); P =0.043], emergency [6.35, (3.39-11.89); P <0.001] and urgent versus [1.78, (1.12-2.84); P =0.015] elective surgery, admission through the emergency department [15.97, (2.00-127.31); P =0.009], or inpatient service [32.28, (7.75-134.46); P <0.001] versus outpatients were associated with mortality in the multivariable analysis. Among all specialties, thoracic surgery [3.76, (1.66-8.53); P =0.002] had the highest association with mortality. Total 17.5% of the patients required intensive care unit admission with increased body mass index being a predictor [1.03, (1.01-1.05); P =0.005]. CONCLUSIONS: COVID-19-positive patients have higher risk of postintervention mortality. Risk factors should be carefully evaluated before intervention. Further studies are needed to understand the impact of pandemic on long-term surgical/procedural outcomes.

Endoluminal Surgery Using a New Enabling Platform With Working Channels to Facilitate Endoscopic Submucosal Dissection in the Treatment of Complex Colorectal Lesions.

BACKGROUND: Although endoscopic submucosal dissection provides higher en-bloc resection rates for larger colorectal lesions, it has not been widely adopted because of technical difficulties. Here we present our initial experience with a novel device facilitating endoluminal surgery. IMPACT OF INNOVATION: The impact of innovation is the development of an endoluminal device increasing the utilization of the endoscopic submucosal dissection technique with higher success rates and lower complications. TECHNOLOGY MATERIALS AND METHODS: This was a single-center experimental feasibility study involving 15 patients who had undergone endoscopic submucosal dissection between August 2019 and December 2020. The DiLumen C2 device was used selectively in patients with complex colorectal lesions. PRELIMINARY RESULTS: Fifteen patients with complex colorectal lesions underwent endoscopic submucosal dissection with a mean age of 64.5 years. The mean lesion size was 40.7 mm. All patients except 1 had an R0 en-bloc endoscopic submucosal dissection resection. There were no procedural or postprocedural complications. The median length of stay was 1 day. CONCLUSION: We report the safety and feasibility of the novel endoscopic platform facilitating en-bloc resection of colorectal lesions. FUTURE DIRECTIONS: The study needs validation in larger comparative series of patients with longer follow-up.

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.

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.

Surgical Repair of Postoperative Perineal Hernia: A Case for the Perineal Approach.

BACKGROUND: Perineal hernia is a well-known, rare complication following abdominoperineal resection for rectal cancer. Due to its rarity, the literature on its surgical repair is comprised of case reports and small case series, and not one surgical approach has been established as superior. OBJECTIVE: This study aimed to identify the repair methods used at our institution and their outcomes. We hypothesized that a perineal approach would have a similar recurrence rate to a transabdominal repair with shorter hospital length of stay. DESIGN: This study was a retrospective case series. SETTINGS: This study was conducted in a large, single institution setting. PATIENTS: Patients who underwent surgical repair for perineal hernia from January 2009 to December 2019 were included. MAIN OUTCOME MEASURES: The primary outcomes were perineal hernia recurrence, surgical approach to repair, and length of stay. RESULTS: We identified 36 patients who underwent surgical repair of perineal hernia at our institution. Twenty patients received neoadjuvant chemoradiation therapy. Most patients (29) had previously undergone abdominoperineal resection; 5 were robotic, 15 were laparoscopic, 1 was robotic converted to open, and 8 were open. Patients were repaired through a perineal approach (22) or transabdominally (14). The median length of stay was 4 days (1-12) after a perineal approach and 8 days (3-18) after a transabdominal approach. At a median follow-up of 12.7 months (1-72), there were 4 recurrences after perineal repair and 3 recurrences after transabdominal repair. LIMITATIONS: This study was limited by its small sample size (36), the retrospective and nonrandomized nature of the case series, and a lack of routine postoperative imaging. A median follow-up length of 12.7 months may not be adequate to detect all recurrences. CONCLUSIONS: This case series supports the perineal approach for surgical repair; it should be the first approach considered, as it is less invasive and may be associated with shorter length of stay compared to an open transabdominal approach. Male gender and neoadjuvant chemotherapy may be possible risk factors for the development of perineal hernia after abdominoperineal resection. See Video Abstract at http://links.lww.com/DCR/B856. REPARACIN QUIRRGICA DE HERNIA PERINEAL POSOPERATORIA UN CASO PARA EL ABORDAJE PERINEAL: ANTECEDENTES:La hernia perineal es una complicación rara y bien conocida después de la resección abdominoperineal por cáncer de recto. Debido a su rareza, la literatura sobre su reparación quirúrgica se compone de informes de casos y pequeñas series de casos, y ningún abordaje quirúrgico se ha establecido como superior.OBJETIVO:El presente estudio tuvo como objetivo identificar los métodos de reparación utilizados en nuestra institución y sus resultados. Presumimos que un abordaje perineal tendría una tasa de recurrencia similar a una reparación transabdominal, con una estancia hospitalaria más corta.DISEÑO:Ésta es una serie de casos retrospectiva.AJUSTES:El escenario fue una gran institución única.PACIENTES:Los pacientes que se sometieron a reparación quirúrgica por hernia perineal desde enero del 2009 hasta diciembre del 2019 se incluyeron en la revisión.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados primarios fueron la recurrencia de la hernia perineal, el abordaje quirúrgico para la reparación y la duración de la estadía.RESULTADOS:Identificamos 36 pacientes que fueron sometidos a reparación quirúrgica de hernia perineal en nuestra institución. La mayoría de los pacientes recibieron quimiorradioterapia neoadyuvante (n = 20). La mayoría de los pacientes (n = 29) se habrían sometido previamente a una resección abdominoperineal (n = 5 robótica, n = 15 laparoscópica, n = 1 robótica convertida a abierta, n = 8 abierta). Los pacientes fueron reparados mediante un abordaje perineal (n = 22) o transabdominal (n = 14). La mediana de la estancia hospitalaria fue de 4 días (rango, 1-12) después de un abordaje perineal y de 8 días (rango 3-18) después de un abordaje transabdominal. En una mediana de seguimiento de 12,7 meses (rango, 1-72) hubo 4 recurrencias después de la reparación perineal y 3 recurrencias después de la transabdominal.LIMITACIONES:El tamaño de la muestra pequeño (n = 36), la naturaleza retrospectiva y no aleatorizada de la serie de casos, la falta de imágenes posoperatorias de rutina, la mediana de seguimiento de 12,7 meses puede no ser adecuada para detectar todas las recurrencias.CONCLUSIONES:Esta serie de casos apoya el abordaje perineal para la reparación quirúrgica; debe ser el primer abordaje considerado, ya que es menos invasivo y puede estar asociado con una estadía más corta en comparación con el abordaje transabdominal abierto. El sexo masculino y la quimioterapia neoadyuvante podrían ser posibles factores de riesgo para el desarrollo de hernia perineal después de la resección abdominoperineal.

A Comparison of Perineal Myocutaneous Flaps Following Abdominoperineal Excision of the Rectum for Anorectal Pathology.

BACKGROUND: Flap-based reconstruction following abdominoperineal resection has been used to address the resultant soft tissue defect and reduce postoperative wound complications. Vertical rectus abdominis myocutaneous flaps have been the traditional choice, but locoregional flaps have attracted attention in minimally invasive resection because they avoid additional abdominal dissection. However, few data exist comparing flap types. OBJECTIVE: To compare outcomes for different types of perineal reconstruction in patients undergoing abdominoperineal resection exclusively for anorectal pathology. DESIGN: This was a retrospective comparative study. SETTING: This study was conducted at a large, tertiary referral institution. PATIENTS: Following Institutional Review Board approval, prospectively maintained clinical and financial databases were interrogated and cross-referenced for patients undergoing proctectomy or abdominoperineal resection with flap reconstruction from 2007 to 2018. Patients with primary gynecological or urological pathology were excluded. MAIN OUTCOME MEASURES: The primary outcome was flap complication rate. Secondary outcomes included perineal hernia rate, donor site complications, emergency department consult after discharge, readmission <90 days, and length of stay. Data were analyzed using univariate and multivariate techniques. RESULTS: A total of 135 patients (79 female, median age 58 years) were included: 68 rectus, 52 gluteal, and 15 gracilis flap reconstructions. Median follow-up was 46 months. Rates of both major and minor flap complications were similar for rectus and gluteal flaps, even when controlling for differences between groups via multivariate analysis ( p > 0.9), including extent of resection and use of mesh. For all flaps, American Society of Anesthesiology score ≥3 was the only independent predictor of major, but not minor, flap complications. For rectus and gluteal flaps, smoking, female sex, and American Society of Anesthesiology score ≥3 were independent predictors of major flap complications ( p < 0.05). LIMITATIONS: This study was limited by its retrospective nature and potential selection bias associated with flap choice; it was also impossible to quantify defect size. CONCLUSION: Gluteal flaps have similar complication rates to rectus flaps and may be considered for patients who are otherwise suitable for minimally invasive abdominoperineal resection.

ANTECEDENTES: La reconstrucción con colgajo después de la resección abdominoperineal se ha utilizado para abordar el defecto de tejido blando resultante y reducir las complicaciones postoperatorias de la herida. Los colgajos miocutáneos verticales del recto abdominal han sido la elección tradicional, pero los colgajos locorregionales han atraído la atención en la resección mínimamente invasiva porque evitan la disección abdominal adicional. Sin embargo, existen pocos datos que comparen los tipos de colgajos.

Pushing the Envelope in Endoscopic Submucosal Dissection: Is It Feasible and Safe in Scarred Lesions?

BACKGROUND: Endoscopic submucosal dissection is an established advanced polypectomy technique to manage large colorectal polyps. OBJECTIVE: The purpose of this study was to evaluate patients who had endoscopic submucosal dissection in the setting of significant scarring attributed to a previous intervention to determine whether this is safe and feasible. DESIGN: The study used a prospectively maintained database. SETTINGS: A scarred lesion was defined as a nonlifting polyp with a history of previous attempted removal with endoscopic mucosal resection, snare, or biopsy where there was no suspicion of malignancy. PATIENTS: All consecutive patients in the previous 14 months were included. INTERVENTION: Endoscopic submucosal dissection was the study intervention. MAIN OUTCOME MEASURES: Thirty-day morbidity and mortality, readmission, length of stay, and recurrence were measured. RESULTS: Ninety-one patients had endoscopic submucosal dissection over a 14-month period with a median polyp size of 31.5 mm (range, 20-45 mm). Eleven patients (12%) were confirmed as having significant scar. There were significantly more previous endoscopic mucosal resections in the scarred group (scarred: 63.6% vs nonscarred: 2.5%; p < 0.001). Significantly more of the scarred patients had their endoscopic submucosal dissection in the operating room versus the endoscopy suite (scarred: 82.0% vs nonscarred: 17.5%; p < 0.001). The 30-day morbidity rate was 18.7%. There were no mortalities. There was no difference in 30-day morbidity between scarred and nonscarred lesions (scarred: 9% vs nonscarred: 20%; p = 0.4). There were more day-case procedures in the nonscarred group (nonscarred: 93.7% vs scarred: 36.4%; p < 0.001). There was no malignancy on final pathology in the scarred group. There was no difference in readmission rate between the scarred and nonscarred lesions. The overall follow-up colonoscopy rate was 53%, and there were no polyp recurrences identified. LIMITATIONS: The study was limited by its small sample size, single institute, surgeon experience, and short follow-up. CONCLUSIONS: Not only is endoscopic submucosal dissection in patients who have scarred lesions technically feasible and safe, it avoids a bowel resection in the majority of patients who have exhausted other advanced endoscopy techniques.

EMPUJAR EL SOBRE EN LA DISECCIN ENDOSCPICA SUBMUCOSA ES FACTIBLE Y SEGURO EN LESIONES CICATRIZADAS: ANTECEDENTES:La disección endoscópica submucosa es una técnica de polipectomía avanzada establecida para tratar pólipos colorrectales grandes.OBJETIVO:Evaluar a pacientes que se sometieron a disección submucosa endoscópica en el contexto de cicatrices significativas debido a una intervención previa para determinar si esto es seguro y factible.DISEÑO:Base de datos mantenida prospectivamente.AJUSTE:Una lesión cicatrizada se definió como un pólipo que no se levanta con antecedentes de intento de extirpación previa con resección endoscópica de la mucosa, lazo o biopsia, donde no había sospecha de malignidad.PACIENTES:Todos los pacientes consecutivos en los últimos 14 meses.INTERVENCIÓN:Disección submucosa endoscópica.MEDIDAS DE RESULTADOS PRINCIPALES:Morbilidad y mortalidad a 30 días, reingreso, duración de la estadía, recurrencia.RESULTADOS:Noventa y un pacientes tuvieron disección submucosa endoscópica durante un período de 14 meses con tamaño de pólipo mediana de 31,5 mm (rango, 20 - 45 mm). Se confirmó que once pacientes (12%) tenían una cicatriz significativa. Hubo significativamente más resecciones de mucosa endoscópica previas en el grupo con cicatrices (con cicatrices: 63,6% vs. sin cicatrices: 2,5%, p <0,001). Significativamente más de los pacientes con cicatrices tuvieron su disección submucosa endoscópica en el quirófano en comparación con la sala de endoscopia (con cicatrices: 82% vs. sin cicatrices: 17.5%, p <0.001). La tasa de morbilidad a 30 días fue del 18,7%. No hubo muertes. No hubo diferencia en la morbilidad a 30 días entre las lesiones cicatrizadas y no cicatrizadas (cicatrizadas: 9% frente a no cicatrizadas: 20%, p = 0,4). Hubo más procedimientos ambulatorios en el grupo sin cicatrices (sin cicatrices: 93,7% frente a cicatrices: 36,36%, p <0,001). No hubo malignidad en la patología final en el grupo con cicatrices. No hubo diferencia en la tasa de reingreso entre las lesiones cicatrizadas y no cicatrizadas. La tasa general de colonoscopia de seguimiento fue del 53% y no se identificaron recurrencias de pólipos.LIMITACIONES:Tamaño de muestra pequeño, experiencia de un solo instituto y cirujanos y seguimiento corto.CONCLUSIÓN:La disección endoscópica submucosa en pacientes con lesiones cicatrizadas no solo es técnicamente factible y segura, sino que evita una resección intestinal en la mayoría de los pacientes que han agotado otras técnicas endoscópicas avanzadas.

What Is the Best Surgical Treatment of Pouch-Vaginal Fistulas?

BACKGROUND: Pouch-vaginal fistula is a debilitating condition with no single best surgical treatment described. Closure of these fistulas can be incredibly difficult, and transanal, transabdominal, and transvaginal approaches have been reported with varying success rates. Recurrence is a major problem and could eventually result in repeat redo pouch or permanent diversion. OBJECTIVE: The aim of our study was to investigate healing rates for procedures done for pouch-vaginal fistula closure. DESIGN: This is a retrospective analysis of a prospectively maintained database complemented by chart review. SETTINGS: This study reports data of a tertiary referral center. PATIENTS: Patients who underwent surgery for pouch-vaginal fistula from 2010 to 2017 were identified. Patients who underwent surgery with intent to close the fistula were included, and patients who had inadequate follow-up to verify fistula status were excluded. INTERVENTIONS: Patients included underwent surgery to close pouch-vaginal fistula. MAIN OUTCOME MEASURES: Success of the surgery was the main outcome measure. Success was defined as procedures with no reported recurrence of fistula on last follow-up. RESULTS: A total of 70 patients underwent surgery with an intent to close the pouch-vaginal fistula, 65 of whom had undergone index IPAA for ulcerative colitis, but 13 of these patients later had the diagnosis changed to Crohn's disease. Thirty-nine patients (56%) had a fistula originating from anal transition zone to dentate line to the vagina (not at the pouch anastomosis). In the total group of 70 patients, our successful closure rate was 39 (56%) of 70. Procedures with the highest success rates were perineal ileal pouch advancement flap and redo IPAA (61% and 69%). LIMITATIONS: The retrospective nature and small number of cases are the limitations of the study. CONCLUSIONS: Although numerous procedures may be used in an attempt to close pouch-vaginal fistula, pouch advancement and redo pouch were the most successful in closing the fistula.

Colorectal Surgery Resident Participation in Screening Colonoscopies: How Does It Impact Quality?

BACKGROUND: Performing colonoscopies is an integral component of colorectal surgery residency training. There exists a paucity of literature regarding colonoscopy quality metrics with colorectal trainee involvement. OBJECTIVE: This study aimed to investigate the effect of colorectal surgery resident participation on quality metrics in screening colonoscopy. DESIGN: Screening colonoscopies performed between August 1, 2016, and July 31, 2018, were queried from a prospectively maintained institutional database. Data were cross-checked with resident case logs to verify colonoscopies with resident participation. SETTING: This study was conducted by the colorectal surgery department at a tertiary level hospital in the United States. PATIENTS: Consecutive, asymptomatic patients aged ≥45 years, undergoing screening colonoscopy, were selected. MAIN OUTCOME MEASURES: The quality parameters measured included overall, male, and female adenoma detection rates; total examination time; withdrawal time; cecal intubation rate; quality of bowel preparation; complications; and medication dosage. RESULTS: A total of 4594 patients were included in the study with a mean age of 60.5 ± 8.4 years (range, 45-91); 51.7% were women. Overall, 4186 of the colonoscopies were performed without resident participation, and 408 were performed with resident participation. Scope insertion, withdrawal, and total examination times were longer in the resident group. Cecal intubation rate, polypectomy rate, sex-specific and overall adenoma detection rates, and complication rates were similar between the groups. In the multivariate model, trainee involvement had no significant impact on adenoma detection rate. In addition, the trainee group utilized a higher mean dose of fentanyl. LIMITATIONS: The retrospective nature of the data with possible coding errors of the database and the inability to quantify the amount of resident participation and to clarify the degree of attending surgeon assistance and oversight were limitations of the study. CONCLUSIONS: Colorectal surgery resident participation in screening colonoscopy takes longer and appears safe, while achieving all national quality metrics without compromising adenoma detection rates. Changes in colonoscopy scheduling in regard to length of time may prove beneficial when there is resident participation. See Video Abstract at http://links.lww.com/DCR/B43. PARTICIPACIÓN DE LOS RESIDENTES DE CIRUGÍA COLORRECTAL EN COLONOSCOPIAS DE CRIBADO: ¿CÓMO AFECTA LA CALIDAD?: La realización de colonoscopias es un componente integral del entrenamiento de residencia en cirugía colorrectal.

Los datos se cotejaron con registros de casos de residentes para verificar las colonoscopias con participación de residentes.Departamento de cirugía colorrectal en un hospital de tercer nivel de los Estados Unidos.Pacientes consecutivos, asintomáticos, edad ≥45 años, sometidos a colonoscopia de detección.Parámetros de calidad que incluyen tasas generales de detección de adenoma en hombres y mujeres, tiempo total de examen, tiempo de retiro, tasa de intubación cecal, calidad de la preparación intestinal, complicaciones y dosis de medicamentos.Se incluyeron un total de 4.594 pacientes en el estudio con una edad media de 60,5 ± 8,4 años (rango, 45-91) y 51,7% mujeres. En total 4,186 de las colonoscopias se realizaron sin participación de los residentes y 408 se realizaron con la participación de los residentes. Los tiempos de inserción, retiro y examen total del alcance fueron más largos en el grupo residentes. La tasa de intubación cecal, la tasa de polipectomía, las tasas de detección de adenoma específicos de género y generales, y las tasas de complicaciones fueron similares entre los grupos. En el modelo multivariado, la participación de los aprendices no tuvo un impacto significativo en la tasa de detección de adenoma. Además, el grupo de aprendices utilizó una dosis media más alta de fentanilo.Carácter retrospectivo de los datos con posibles errores de codificación de la base de datos. Incapacidad para cuantificar la cantidad de participación de los residentes y para aclarar el grado de asistencia y supervisión del cirujano.La participación de los residentes de cirugía colorrectal en la colonoscopia de cribado lleva más tiempo y parece segura, mientras se logran todas las medidas de calidad nacionales sin comprometer las tasas de detección de adenoma. Los cambios en la programación de la colonoscopia con respecto al período de tiempo pueden ser beneficiosos cuando hay participación de residentes.

Diverticular Colovaginal Fistulas: What Factors Contribute to Successful Surgical Management?

BACKGROUND: Diverticular disease is the leading cause of colovaginal fistulas. Surgery is challenging given the inflammatory process that makes dissection difficult. To date, studies are small and include fistula secondary to multiple etiologies. OBJECTIVE: The objectives of this study were to examine surgical outcomes of diverticular colovaginal fistulas and to identify variables associated with successful closure. DESIGN: This was a retrospective study of a prospectively maintained clinical database. SETTINGS: The study was conducted at a single tertiary referral center. PATIENTS: Women with diverticular colovaginal fistulas, who underwent surgical repair with intent to close the fistula, were included. INTERVENTIONS: Repair of colovaginal fistula through minimally invasive or open techniques was involved. MAIN OUTCOME MEASURES: Successful closure of fistula, defined as resolution of symptoms and no stoma, was measured. RESULTS: Fifty-two patients underwent surgical treatment of diverticular colovaginal fistula, 23 (44%) of whom underwent a minimally invasive approach (conversion rate of 22%). Ostomy construction and omental pedicle flaps were used in 28 (54%) and 38 patients (73%). Surgery was successful in 47 patients (90%). Accounting for secondary operations, ultimate success and failure rates were 49 (94.0%) and 3 (5.7%). There was no difference in postoperative morbidity between the 2 groups (5 patients with Clavien-Dindo III/IV complications in the success group versus 2 patients in the failure group; 10.6% vs 40.0%; p = 0.44). Failure to achieve fistula closure was not associated with perioperative variables, age, BMI, diabetes mellitus, ASA grade, steroid use, previous abdominal surgery or hysterectomy, use of omentoplasty, or ostomy. Patients who failed were more likely to be smokers (60.0% vs 12.8%; p = 0.03). LIMITATIONS: Limitations include the retrospective design and lack of power. CONCLUSIONS: Surgery is effective in achieving successful closure of diverticular colovaginal fistula. Smokers should be encouraged to stop before embarking on an elective repair. Although the use of fecal diversion and omental pedicle flaps did not correlate with success, they should be used when clinically appropriate. See Video Abstract at http://links.lww.com/DCR/A983. FÍSTULAS COLOVAGINALES DIVERTICULARES ¿QUÉ FACTORES CONTRIBUYEN AL ÉXITO DEL TRATAMIENTO QUIRÚRGICO?: La enfermedad diverticular es la causa principal de fístulas colovaginales. La cirugía es un reto dado el proceso inflamatorio que dificulta la disección. Hasta la fecha, los estudios son pequeños e incluyen fístulas secundarias a múltiples etiologías. OBJETIVO: 1) Examinar los resultados quirúrgicos de las fístulas colovaginales diverticulares; 2) Identificar variables asociadas a un cierre exitoso. DISEÑO:: Estudio retrospectivo de una base de datos clínicos prospectivamente mantenida. CONFIGURACIÓN:: Centro de referencia superior. PACIENTES: Mujeres con fístulas colovaginales diverticulares, que se sometieron a una reparación quirúrgica con la intención de cerrar la fístula. INTERVENCIONES: Reparación de la fístula colovaginal mediante técnicas mínimamente invasivas o abiertas. MEDIDAS DE RESULTADOS PRINCIPALES: Cierre exitoso de la fístula definida como resolución de los síntomas y sin estoma. RESULTADOS: Cincuenta y dos pacientes se sometieron a tratamiento quirúrgico de la fístula colovaginal diverticular, 23 (44%) de los cuales se sometieron a un acceso mínimamente invasivo (tasa de conversión del 22%). La construcción de la ostomía y los pedículos omentales se utilizaron en 28 (54%) y 38 pacientes (73%), respectivamente. La cirugía fue exitosa en 47 pacientes (90%). Tomando en cuenta las operaciones secundarias, las tasas finales de éxito y fracaso fueron 49 (94.0%) y 3 (5.7%). No hubo diferencias en la morbilidad postoperatoria entre los dos grupos (5 pacientes con complicaciones de Clavien-Dindo III / IV en el grupo de éxito versus a 2 pacientes en el grupo de fracaso, 10.6% versus a 40.0%; p = 0.44). El fracaso para lograr el cierre de la fístula no se asoció con variables perioperatorios, edad, IMC, diabetes, grado ASA, uso de esteroides, cirugía abdominal previa o histerectomía, uso de omentoplastia u ostomía. Los pacientes que fracasaron eran más propensos a ser fumadores (60.0% versus a 12.8%; p = 0.03). LIMITACIONES: Las limitaciones incluyen el diseño retrospectivo y la falta de poder. CONCLUSIONES: La cirugía es efectiva para lograr el cierre exitoso de la fístula colovaginal diverticular. Se debe aconsejar a los fumadores a parar de fumar antes de embarcarse en una reparación electiva. Mientras el uso de desviación fecal y pedículos omentales no se correlacionó con el éxito, deberían utilizarse cuando sea clínicamente apropiado.

Pediatric Colorectal Surgery: A Collaborative Approach From a Single Institution.

BACKGROUND: Inflammatory bowel disease encompasses relapsing gastrointestinal disorders commonly presenting in pediatric patients, with 25% of diagnoses made before age 20 and 4% before age 5. Considering the need for life-long surgical follow-up, a collaborative system involving both pediatric and colorectal surgeons could improve overall patient experiences. We hypothesized that cases performed in collaboration with both pediatric and adult colorectal surgeons may lead to better outcomes. METHODS: Data were gathered retrospectively for 116 patients 18 y old or younger who underwent colorectal resections for inflammatory bowel disease between 2010 and 2017 at our institution. Data included patient demographics, type of procedure, surgical approach, specimen extraction site, surgeon involvement (pediatric, colorectal, or collaborative), operative time, and estimated blood loss. We analyzed days until passage of flatus and bowel movement, length of stay, type of surgical procedure, and surgical complications. RESULTS: Our data showed that days until flatus (2.27 ± 0.47, P = 0.049), first bowel movement (2.64 ± 0.67, P = 0.006), and length of stay (4.45 ± 1.51, P = 0.006) were the shortest in the collaborative group. We also found that single-incision laparoscopic surgery was significantly more common in the collaborative group (77.8%, P = 0.002). We did not see a difference in surgical complication rates among any of the groups. CONCLUSIONS: Our study showed short-term beneficial outcomes in a single institution associated with the collaboration of pediatric surgeons and colorectal surgeons on pediatric colorectal cases in comparison to those performed by pediatric surgeons or adult colorectal surgeons alone.

Minimally Invasive Surgery in Complex Crohn's Disease.

Minimally invasive approaches are safe, feasible, and often recommended as the initial choice in the surgical management of Crohn's disease. However, a consensus has not been reached as the ideal approach in the surgical treatment of complex and recurrent Crohn's disease. Laparoscopy may provide advantages such as shorter length of stay and decreased postoperative pain and result in less adhesion formation in patients with complex disease. Robotic techniques may be beneficial in selected patients for completion proctectomy, providing better visualization in the narrow pelvis and increased dexterity. Decision of surgical technique should be made on a case-by-case basis.

Colonoscopy-induced acute diverticulitis: myth or reality?

BACKGROUND: Colonoscopy in patients with diverticulosis can be technically challenging and limited data exist relating to the risk of post-colonoscopy diverticulitis. Our aim was to evaluate the incidence, management, and outcomes of acute diverticulitis following colonoscopy. METHODS: Study design is retrospective cohort study. Data were gathered by conducting an automated search of the electronic patient database using current procedural terminology and ICD-9 codes. Patients who underwent a colonoscopy from 2003 to 2012 were reviewed to find patients who developed acute diverticulitis within 30 days after colonoscopy. Patient demographics and colonoscopy-related outcomes were documented, which include interval between colonoscopy and diverticulitis, colonoscopy indication, simultaneous colonoscopic interventions, and follow-up after colonoscopy. RESULTS: From 236,377 colonoscopies performed during the study period, 68 patients (mean age 56 years) developed post-colonoscopy diverticulitis (0.029%; 2.9 per 10,000 colonoscopies). Incomplete colonoscopies were more frequent among patients with a history of previous diverticulitis [n = 10 (29%) vs. n = 3 (9%), p = 0.03]. Mean time to develop diverticulitis after colonoscopy was 12 ± 8 days, and 30 (44%) patients required hospitalization. 34 (50%) patients had a history of diverticulitis prior to colonoscopy. Among those patients, 14 underwent colonoscopy with an indication of surveillance for previous disease. When colonoscopy was performed within 6 weeks of a diverticulitis attack, surgical intervention was required more often when compared with colonoscopies performed after 6 weeks of an acute attack [n = 6 (100%) vs. n = 10 (36%), p = 0.006]. 6 (9%) out of 68 patients received emergency surgical treatment. 15 (24%) out of 62 patients who had non-surgical treatment initially underwent an elective sigmoidectomy at a later date. Recurrent diverticulitis developed in 16 (23%) patients after post-colonoscopy diverticulitis. CONCLUSIONS: Post-colonoscopy diverticulitis is a rare, but potentially serious complication. Although a rare entity, possibility of this complication should be kept in mind in patients presenting with symptoms after colonoscopy.
