RESUMEN

BACKGROUND: Ileal pouch-anal anastomosis (IPAA) is considered the preferred restorative surgical procedure for patients with ulcerative colitis and familial adenomatous polyposis requiring proctocolectomy. Unfortunately, postoperative leaks remain a complication with potentially significant ramifications. This study aimed to provide a comprehensive description of the evaluation, management, and outcomes of leaks after primary IPAA procedures. METHODS: Between 1995 and 2022, a total of 4058 primary IPAA procedures were performed at Cleveland Clinic. From a prospectively maintained pouch registry, we retrospectively reviewed the data of 237 patients who presented to the pouch center for management. Of these, 114 (3%) had undergone the index IPAA procedure at our clinic (de novo cases), whereas 123 patients had their index IPAA performed elsewhere. Data were missing for 43 patients, resulting in a final cohort of 194 patients. RESULTS: Our cohort had an average age of 41 years (range, 16-76) at the time of leak diagnosis. Overall, 55.2% were males, average body mass index was 24.4 kg/m2, and pain was the most prevalent presenting symptom (61.8%), followed by fever (34%). Leaks were confirmed through diagnostic testing in 141 cases, whereas 27.3% were detected intraoperatively. The most common initial diagnoses were pelvic abscess (47.4%) and enteric fistulas (26.8%), including cutaneous (9.8%), vaginal (7.2%), and bladder fistulas (3.1%). By location, leaks occurred at the tip of the "J" (52.6%), at the pouch-anal anastomotic site (35%), and in the body of the pouch (12.4%). A nonoperative management approach was initially attempted in 49.5% of cases, including antibiotic therapy, drainage, endoclip, and endo-sponge, with a success rate of 18.5%. Surgery was eventually required in 81.4% of patients, including (1) sutured or stapled pouch repair (52.5%), with diversion performed in 87.9% of these cases either before or during the salvage surgery; (2) pouch excision with neo-IPAA (22.7%), including 9 patients from the first group; and (3) pouch disconnection, repair, and reanastomosis (9.3%). Pouch failure occurred in 8.4%, with either pouch excision (11.1%) or permanent diversion (4.5%). Ultimately, 12.4% of patients (24 of 194) required permanent diversion, with all necessitating pouch excision. In the 30-day follow-up after salvage surgery, short-term complications arose in 38.7% of patients. The most common complications observed were ileus, pelvic abscess/sepsis, and fever. CONCLUSION: Leaks after primary IPAA procedures represent an infrequent, yet challenging, complication. Despite attempts at nonoperative management, the success rate is limited. Salvage surgery is associated with a high pouch retention rate, underscoring its importance in the management of post-IPAA leaks.

RESUMEN

PURPOSE: This study aims to compare the outcomes of repair/redo ileal pouch-anal anastomosis (repair/redo-IPAA) with the conversion of IPAA to continent ileostomy (CI) in an effort to prevent the need for a permanent ileostomy (IS) following IPAA failure. METHODS: This research involved a retrospective analysis of surgical records, employing descriptive statistics and Kaplan-Meier survival analysis. RESULTS: Among 57 patients with an IPAA, up to three revisions were necessary due to complications or complete failure. Ultimately, repair/redo-IPAA preserved the IPAA in 14 patients (24.6%), conversion to CI salvaged the pouch in 21 patients (36.8%), and IS was unavoidable in 22 patients (38.6%). The cumulative probability of requiring conversion surgery was calculated to be 54.0% at 20 years, thereby reducing the cumulative risk of IS to 32.3%. The 20-year cumulative probability of pouch salvage by repair/redo IPAA was only 21.9%. However, this rate increased to 67.7% when conversion procedures were considered. Following repair/redo-IPAA, only 8.3% of patients reported evacuation frequencies of ≤ 4 during the day, and 16.7% were evacuation-free at night. In contrast, after conversion to CI, 98.0% of patients reported a maximum of four evacuations in a 24-h period. After undergoing repair/redo IPAA, between half and two-thirds of patients reported experiencing incontinence or soiling, while complete continence was achieved in all patients following conversion to CI. Notably, the majority of patients expressed overall satisfaction with their respective procedures. A positive correlation was identified between very high subjective satisfaction and positive objective surgical outcomes exclusively in patients who underwent conversion to CI. CONCLUSION: When complications or failure of IPAA occur, conversion to CI emerges as a highly viable alternative to repair/redo IPAA. This conclusion is supported by the observation that patient satisfaction appears to be closely tied to stable surgical outcomes. To reinforce these findings, further prospective studies are warranted.

RESUMEN

AIM: Rates of pouch failure after total proctocolectomy with ileal pouch-anal anastomosis (IPAA) range from 5% to 18%. There is little consistency across studies regarding the factors associated with failure, and most include patients who underwent IPAA in the pre-biologic era. Our aim was to analyse a cohort of patients who underwent IPAA in the biologic era at a large-volume inflammatory bowel disease institution to better determine preoperative, perioperative and postoperative factors associated with pouch failure. METHODS: A retrospective cohort analysis was performed with data from an institutional review board approved prospective database with ulcerative colitis or unclassified inflammatory bowel disease patients who underwent total proctocolectomy with IPAA at Mount Sinai Hospital between 2008 and 2017. Preoperative, perioperative and postoperative data were collected and univariate and multivariate analyses were performed to identify factors associated with increased risk of pouch failure. RESULTS: Out of 664 patients included in the study, pouch failure occurred in 41 (6.2%) patients, a median of 23.3 months after final surgical stage. Of these, 17 (41.4%) underwent pouch excision and 24 (58.5%) had diverting ileostomies. The most common indications for pouch failure were Crohn's disease like pouch inflammation (CDLPI) (n = 17, 41.5%), chronic pouchitis (n = 6, 14.6%), chronic cuffitis (n = 5, 12.2%) and anastomotic stricture (n = 4, 9.8%). On multivariate analysis, pre-colectomy biologic use (hazard ratio [HR] 2.25, 95% CI 1.09-4.67), CDLPI (HR 3.18, 95% CI 1.49-6.76) and pouch revision (HR 2.59, 95% CI 1.26-5.32) were significantly associated with pouch failure. CONCLUSIONS: Pouch failure was significantly associated with CDLPI, preoperative biologic use and pouch revision; however, reassuringly it was not associated with postoperative complications.

RESUMEN

BACKGROUND: In medically refractory Ulcerative Colitis (UC), proctocolectomy with ileoanal pouch procedure (IAPP) is the preferred continence-preserving surgical option. Functional outcomes post-surgery and long-term complication rates in the biologic era remain ambiguous. This review primarily aims to provide an update on these outcomes. Secondarily, risk factors associated with chronic pouchitis and pouch failure are explored. METHODS: Two online databases (MEDLINE and EMBASE) were searched on 4 October 2022 for English studies from 2011-present relating to long-term outcomes of IAPP in inflammatory bowel disease (IBD) patients. Adult patients with 12 month follow-up were included. Studies focused on 30-day post-operative outcomes, non-IBD patients or studies including less than 30 patients were excluded. RESULTS: Following screening and full-text review of 1094 studies, 49 were included. Median sample size was n = 282 (IQR: 116-519). Median incidences for chronic pouchitis and pouch failure were 17.1% (IQR: 12-23.6%) and 6.9% (IQR: 4.8-10.8%), respectively. Upon multivariate analysis, chronic pouchitis development was most significantly associated with pre-operative steroid use, pancolitis and extra-intestinal IBD manifestations, whilst pouch failure was most significantly associated with pre-operative diagnosis of Crohn's disease (compared to UC), peri-operative pelvic sepsis and anastomotic leak. Overall patient satisfaction was very high with four included studies reporting greater than 90% satisfaction rates. CONCLUSION: Long-term complications for IAPP were common. However, despite this, patient satisfaction post-IAPP was high. Up-to-date knowledge of complication rates and their risk factors improves pre-operative counselling, management planning and patient outcomes.

RESUMEN

Background: In 10%-20% of cases it is impossible to make a differential diagnosis between ulcerative colitis and Crohn's colitis. A 50% failure rate of J pouch ilea-anal anastomosis is observed in Crohn's colitis. In 2009, we created the Padua Prognostic Score for Colitis (PPSC) to predict the long-term clinical and functional outcome and quality of life of patients undergoing restorative proctocolectomy with J pouch. The aim of the present study is to establish and validate the accuracy of a prognostic score for chronic inflammatory bowel diseases (IBD). Patient population and methods: The PPSC was created in 2009 by integrating clinical and histological information of patients undergoing RPC. It included preoperative perianal abscess or fistula, rectal sparing, terminal ileum involvement, skip lesions and histological diagnosis of indeterminate colitis or Crohn's colitis on the operative specimen. The validity of this score was tested in predicting postoperative abscess or fistula, anal canal disease, pouchitis, pouch failure and new diagnosis of Crohn's disease. Correlation analysis, ROC curve analysis and survival analysis were used to validate the PPSC in a different cohort from the previous one. Results: We retrospectively enrolled in this study 138 consecutive patients undergoing CPR for ulcerative colitis (n = 127) or indeterminate colitis (n = 11) in our institution since 2005 to 2020. In this period, we observed 11 patients with postoperative abscess or fistula, 3 with anal canal disease, 40 with pouchitis, 6 with pouch failure and 6 with new diagnosis of Crohn's disease. In the new validation cohort, the PPSC confirmed to have a good accuracy in predicting the onset of postoperative CD (AUC = 74.5%, p = 0.018). Kaplan Meier curves demonstrate how a PPSC over 1 can reliably predicts the long-term onset of, pouchitis (p = 0.002) and anal abscess or fistulae (p = 0.04). Conclusions: In this validation study we confirmed the accuracy of the PPSC in predicting postoperative fistulas or abscesses and pouchitis. Therefore, we believe that in clinical practice patients with a PPSC score greater than 1 should be warned of this risk of possible Crohn's disease diagnosis and pouch failure.

RESUMEN

Proctocolectomy with ileal J­pouch-anal and rectal reconstruction is the standard surgical treatment for ulcerative colitis, selected cases of Crohn's disease, FAP and multilocular colon carcinoma. Although this treatment has been continuously developed over the last 40 years, the long-term success rate is 80-90% of the treated patients. The reasons for this are manifold: chronic pouchitis, incontinence, secondary diagnosis of Crohn's disease, fistulas, severe surgical complications, rectal stump left for too long, chronic abscess and surgical technical errors. This article deals with the control of acute complications and with the management of long-term complications. Some of the triggering complications for pouch failure do not generally imply failure of the method. A correction, closure of the fistula and in individual cases also a completely new pouch creation can restore a good pouch function in about 75% of cases. Various indications, techniques and results are presented.

RESUMEN

BACKGROUND: Inflammation of the rectal remnant may affect the postoperative outcome of ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). We aimed to determine the extent of inflammation in the anastomotic area during IPAA and to investigate the impact of proctitis on postoperative complications and long-term outcomes. METHODS: Three hundred thirty-four UC patients with primary IPAA were included in this retrospective case-control study. The histopathologic degree of inflammation in the anastomotic area was graded into three stages of no proctitis ("NOP"), mild to medium proctitis ("MIP"), and severe proctitis ("SEP"). Preoperative risk factors, 30-day morbidity, and follow-up data were assessed. Kaplan-Meier analysis was performed in the event of pouch failure. RESULTS: The prevalence of proctitis was high (MIP 40.4%, and SEP 42.8%). During follow-up, the incidence of complications was highest among SEP: resulting in re-intervention (n = 40; 28.2%, p = 0.017), pouchitis (n = 36; 25.2%, p < 0.01), and pouch failure (n = 32; 22.4%, p = 0.032). The time interval to pouch failure was 5.0 (4.0-6.9) years among NOP, and 1.2 (0.5-2.3) years in SEP (p = 0.036). ASA 3, pouchitis, and pouch fistula were independent risk factors for pouch failure. CONCLUSION: Proctitis at the time of IPAA is common. A high degree of inflammation is associated with poor long-term outcomes, an effect that declines over time. In addition, a higher degree of proctitis leads to earlier pouch failure.

RESUMEN

BACKGROUND: Failed pouches may tend to be managed with only a loop ileostomy in obese patients due to some safety concerns. The effect of obesity on ileal pouch excision outcomes is poorly studied. In our study, we aimed to assess the short-term outcomes after ileal pouch excision in obese patients compared to their nonobese counterparts. METHODS: The patients who underwent pouch excision between 2005 and 2017 were included using ACS-NSQIP participant user files. The operative outcomes were compared between obese (BMI ≥30 kg/m2) and nonobese (BMI<30 kg/m2) groups. RESULTS: There were 507 pouch excision patients included of which eighty (15.7%) of them were obese. Physical status of the obese patients tended to be worse (ASA>3, 56.3 vs 42.9%, P = .027). There were more patients who had diabetes mellitus (DM) and hypertension (HT) in the obese group (26.3% vs. 11.2%, P = .015; 11.3 vs. 4.4%, P < .001, respectively). Operative time was similar between 2 groups (mean ± SD, 275 ± 111 vs. 252±111 minutes, P = .084). Deep incisional SSI was more commonly observed in the obese group (7.5 vs 2.8%, P = .038). In multivariate analysis, only deep incisional SSI was found to be independently associated with obesity (OR: 2.79, 95% CI: 1.02-7.67). Obese patients were readmitted more frequently than nonobese counterparts (28.3 vs 16%, P = .035). The length of hospital stay was comparable [median (IQR), 7 (4-13.5) vs. 7 (5-11) days, P = .942]. CONCLUSION: Ileal pouch excision can be performed in obese patients with largely similar outcomes compared to their nonobese counterparts although obesity is associated with a higher rate of deep space infection.

RESUMEN

Up to 30% of patients with ulcerative colitis (UC) will require surgical management of their disease during their lifetime. An ileal pouch-anal anastomosis (IPAA) is the gold standard of care, giving patients the ability to be free from UC's bowel disease and avoid a permanent ostomy. Despite surgical advancements, a minority of patients will still experience pouch failure which can be debilitating and often require further surgical interventions. Signs and symptoms of pouch failure should be addressed with the appropriate workup and treatment plans formulated according with the patient's wishes. This article will discuss the identification, workup, and treatment options for pouch failure after IPAA.

RESUMEN

BACKGROUND AND AIMS: The ileoanal pouch (IPAA) provides patients with ulcerative colitis (UC) that have not responded to medical therapy an option to retain bowel continuity and defecate without the need for a long-term stoma. Despite good functional outcomes, some pouches fail, requiring permanent diversion, pouchectomy, or a redo pouch. The incidence of pouch failure ranges between 2 and 15% in the literature. We conducted a systematic review and meta-analysis aiming to define the prevalence of pouch failure in patients with UC who have undergone IPAA using population-based studies. METHODS: We searched Embase, Embase classic and PubMed from 1978 to 31st of May 2021 to identify cross-sectional studies that reported the prevalence of pouch failure in adults (≥ 18 years of age) who underwent IPAA for UC. RESULTS: Twenty-six studies comprising 23,389 patients were analysed. With < 5 years of follow-up, the prevalence of pouch failure was 5% (95%CI 3-10%). With ≥ 5 but < 10 years of follow-up, the prevalence was 5% (95%CI 4-7%). This increased to 9% (95%CI 7-16%) with ≥ 10 years of follow-up. The overall prevalence of pouch failure was 6% (95%CI 5-8%). CONCLUSIONS: The overall prevalence of pouch failure in patients over the age of 18 who have undergone restorative proctocolectomy in UC is 6%. These data are important for counselling patients considering this operation. Importantly, for those patients with UC being considered for a pouch, their disease course has often resulted in both physical and psychological morbidity and hence providing accurate expectations for these patients is vital.

RESUMEN

Objective: This systematic review aims to assess the incidence of pouch failure and the correlation between ileal pouch-anal anastomosis (IPAA)-related complications and pouch failure. Background: Previous studies demonstrated wide variation in postoperative complication rates following IPAA. Methods: A systematic review was performed by searching the MEDLINE, EMBASE, and Cochrane Library databases for studies reporting on pouch failure published from January 1, 2010, to May 6, 2020. A meta-analysis was performed using a random-effects model, and the relationship between pouch-related complications and pouch failure was assessed using Spearman's correlations. Results: Thirty studies comprising 22,978 patients were included. Included studies contained heterogenic patient populations, different procedural stages, varying definitions for IPAA-related complications, and different follow-up periods. The pooled pouch failure rate was 7.7% (95% confidence intervals: 5.56-10.59) and 10.3% (95% confidence intervals: 7.24-14.30) for studies with a median follow-up of ≥5 and ≥10 years, respectively. Observed IPAA-related complications were anastomotic leakage (1-17%), pelvic sepsis (2-18%), fistula (1-30%), stricture (1-34%), pouchitis (11-61%), and Crohn's disease of the pouch (0-18%). Pelvic sepsis (r = 0.51, P < 0.05) and fistula (r = 0.63, P < 0.01) were correlated with pouch failure. A sensitivity analysis including studies with a median follow-up of ≥5 years indicated that only fistula was significantly correlated with pouch failure (r = 0.77, P < 0.01). Conclusions: The single long-term determinant of pouch failure was pouch fistula, which is a manifestation of a chronic leak. Therefore, all effort should be taken to prevent an acute leak from becoming a chronic leak by early diagnosis and proactive management of the leak. Mini abstract: This systematic review aims to assess the incidence of pouch failure and the correlation between IPAA-related complications and pouch failure. Long-term pouch failure was correlated with fistula, suggesting that early septic complications may result in fistula formation during long-term follow-up, leading to an increased risk of pouch failure.

RESUMEN

Patients with inflammatory bowel disease (IBD) occasionally need a restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) because of medically refractory colitis or dysplasia/cancer. However, pouchitis may develop in up to 70% of patients after this procedure and significantly impair quality of life, more so if the inflammation becomes a chronic condition. About 10% of patients with IBD who develop pouchitis require pouch excision, and several risk factors of the failure have been reported. A phenotype that has features similar to Crohn's disease may develop in a subset of ulcerative colitis patients following proctocolectomy with IPAA and is the most frequent reason for pouch failure. In this review, we discuss the diagnosis and prognosis of pouchitis, risk factors for pouchitis development, and treatment options for pouchitis, including the newer biological agents.

RESUMEN

BACKGROUND AND AIMS: Patients with ulcerative colitis are often treated with multiple immunomodulative agents to achieve remission. In refractory disease, the next option is frequently proctocolectomy with ileal pouch-anal anastomosis. No consensus exists as to whether immunomodulatory therapy at the time of ileal pouch surgery leads to any increase in postoperative complications. Our aim was to assess, in ulcerative colitis patients with restorative proctocolectomy, the effect of preoperative anti-tumor necrosis factor therapy and corticosteroids on postoperative complications and pouch failure. MATERIALS AND METHODS: A retrospective medical record review of 445 patients with ulcerative colitis who underwent proctocolectomy with ileal pouch-anal anastomosis in Helsinki University Hospital between January 2005 and June 2016. RESULTS: Anti-tumor necrosis factor agents were not associated with postoperative complications. Only high-dose corticosteroids (prednisolone ⩾20 mg or equivalent) were associated with higher incidence of anastomotic leak (12.6% vs 2.5%, P = 0.002) and wound dehiscence (4.2% vs 0%, P = 0.019), but pouch failure rate was no higher (2.1% vs 0%, P = 0.141) than in patients without corticosteroid treatment. A lower dosage of corticosteroids had no effect on early postoperative complications, but pouch failure rate was increased (4.4% vs 0%, P = 0.015). CONCLUSION: Corticosteroids, but not anti-tumor necrosis factor therapy, were associated with postoperative complications. Preoperative use of corticosteroids may increase pouch failure rate, but the risk is still minor in high-volume centers performing ileal pouch surgery.

RESUMEN

INTRODUCTION: An ileal pouch anal anastomosis (IPAA) is the treatment of choice in selected patients to restore intestinal continuity following proctocolectomy. Data on IPAA in the Republic of Ireland is lacking, and surgery for IPAA has evolved over time. The aim of this retrospective study was to report our institutional outcomes from IPAA over a 20-year period. METHODS: Data were retrospectively collated from consecutive primary IPAA cases between 1998 and 2017 at Beaumont Hospital. Patient demographics and operative approach were examined, and pouch failure was estimated using the Kaplan-Meier method. RESULTS: Ninety-five patients underwent IPAA over the study period with a mean follow-up of 9.4 ± 5.6 years. The mean age at IPAA was 35.9 ± 10.0 years, and 58.9% were male. The majority were performed in 3 stages (78.9%), were performed to treat ulcerative colitis (66.3%), were of a J-pouch configuration (96.8%), and had a stapled anastomosis (70.5%). On follow-up, 28.4% reported experiencing at least 1 episode of pouchitis and the 10-year pouch failure rate was 14%. In the last decile of the study period, the mean number of IPAA performed per year increased to 10.5 ± 2.1 (P = 0.013), the age of IPAA formation reduced (P = 0.049), and the proportion completed in a minimally invasive manner increased (P < 0.001). CONCLUSIONS: Acceptable long-term outcomes were observed by our institution. A recent increase in institutional volume, reduction in patient age, and increase in the proportion of cases performed laparoscopically have been identified.

RESUMEN

PURPOSE: Restorative proctocolectomy (RPC) is the most common operation in ulcerative colitis. Nevertheless, permanent ileostomy will sometimes be unavoidable. The aim was to evaluate the reasons for pouch failure and early morbidity after pouch excision. METHODS: The number and the reasons for pouch failures were analysed in patients undergoing RPC 1985-2016. RESULTS: Out of 491 RPC patients, 53 experienced pouch failure (10 women, 43 men); 52 out of 53 underwent pouch excision. The cumulative risk for excision at 5, 10 and 20 years was 5.6, 9.4 and 15.5%, respectively. The reasons for failure included septic events such as fistula in 12 (23%), chronic pouchitis in 11 (21%) and leakage in 8 (15%) patients. Functional reasons for pouch failure were recorded as poor function in 16 (30%), incontinence in 12 (23%) and stricture in 12 (23%) patients. Multiple causes for pouch failure were recorded for individual patients. Seven cases of Crohn's disease were found among the failure cases: two before pouch excision and five after. Altogether, 15 Crohn's disease diagnoses were set in the RPC cohort, giving a percentage of 47% of pouch failure in this disorder. A complication occurred in 23 (44%) patients within 30 days after surgery; 16 were mild (Clavien-Dindo grades I-II). CONCLUSIONS: Eleven percent of RPC patients suffered pouch failure: more men than women. The reasons were multiple. Crohn's disease created a risk of failure, but a half of these patients maintained the pouch. Morbidity after pouch excision was moderate, but in most cases slight.

RESUMEN

BACKGROUND: The causes of chronic antibiotic refractory pouchitis (CARP) and pouch failure in inflammatory bowel disease (IBD) patients remain unknown. Our previous small study showed peripouch fat area measured by MRI was associated with pouchitis. AIMS: To explore the relationship between peripouch fat area on CT imaging and pouch outcomes. METHODS: This is a historical cohort study. Demographic, clinical, and radiographic data of IBD patients with abdominal CT scans after pouch surgery between 2002 and 2017 were collected. Peripouch fat areas and mesenteric peripouch fat areas were measured on CT images at the middle pouch level. RESULTS: A total of 435 IBD patients were included. Patients with higher peripouch fat areas had a higher prevalence of CARP. Univariate analyses demonstrated that long duration of the pouch, high weight or body mass index, the presence of primary sclerosing cholangitis or other autoimmune disorders, and greater peripouch fat area or mesenteric peripouch fat area were risk factors for CARP. Multivariable analyses demonstrated that the presence of primary sclerosing cholangitis or autoimmuned disorders, and greater peripouch fat area (odds ratio [OR] 1.031; 95% confidence interval [CI] 1.016-1.047, P < 0.001) or mesenteric peripouch fat area were independent risk factors for CARP. Of the 435 patients, 139 (32.0%) had two or more CT scans. Multivariable Cox proportional hazard analyses showed that "peripouch fat area increase ≥ 15%" (OR 3.808, 95%CI 1.703-8.517, P = 0.001) was an independent predictor of pouch failure. CONCLUSIONS: A great peripouch fat area measured on CT image is associated with a higher prevalence of CARP, and the accumulation of peripouch fat is a risk factor for pouch failure. The assessment of peripouch fat may be used to monitor the disease course of the ileal pouch.

RESUMEN

PURPOSE: Pouch excision is a major complication of ileoanal pouch surgery. Current practice is for this type of surgery to be performed in a specialist centre. We present a series of patients undergoing pouch excision surgery in a high volume centre in the UK and assess the outcomes in these patients. METHODS: All patients undergoing pouch excision at the Royal Liverpool Hospital between 1995 and 2015 under the care of a single surgeon were included. Demographics and outcomes were taken from patients' notes and a dedicated retrospectively compiled database. RESULTS: 35 patients underwent pouch excision surgery during this period. Around half the patients had their original pouch surgery elsewhere and were referred for management of complications. Median time to pouch excision was 13 years from the original operation. Overall complication rate was 31% with 11% requiring re-intervention post-operatively. There was no mortality in this series. CONCLUSION: Pouch excision is a complex, high-risk procedure that should be carried out in specialist centres. Our series shows that in such settings, good outcomes can be achieved for these patients.

RESUMEN

PURPOSE: Data regarding safety and feasibility of re-do ileal pouch anal anastomosis (IPAA) for failed ileal pouch in children are limited. In this study, we compared the short- and long-term outcomes of re-do IPAA in pediatric and adult populations in a case-matched setting. METHODS: Between March 2007 and June 2017, pediatric patients undergoing a transabdominal re-do IPAA by single surgeon were reviewed and case matched with adult counterparts. Short- and long-term outcomes including complications, functional outcomes, and quality of life of the two groups were compared. RESULTS: 60 patients were included (pediatric, n = 30; adult, n = 30). Time between index IPAA and re-do IPAA was shorter in the pediatric group (30 ± 26 vs 86 ± 74 months, p = 0.001). In the pediatric population, the existing pouch was more commonly used to construct the re-do pouch (n = 19 vs n = 12, p = 0.07). There was a trend towards the presence of less postoperative complications in pediatric group (n = 13 vs n = 20, p = 0.07). There were no reoperations or mortality. Long-term pouch survival was comparable between two groups (p = 0.96). Six re-do IPAAs failed in the study period. CONCLUSION: Re-do IPAA is safe and feasible in pediatric population with failed IPAA and can be performed with similar short- and long-term outcomes compared to adults in experienced hands.

RESUMEN

BACKGROUND: Megapouch is a rare functional complication of restorative proctocolectomy with ileal pouch-anal anastomosis characterized by pouch ± small bowel dilatation with no evidence of obstruction on endoscopy and imaging. Little is known about clinical characteristics and outcomes of this entity. METHODS: We included all patients diagnosed with megapouch at our institution, identified from a pouch database. Data on baseline characteristics, management, and outcomes were documented and analyzed from electronic medical records. Appropriate statistical measures were used. p < 0.05 was considered significant. RESULTS: Twenty-three patients with megapouch were identified. The mean age was 40.7 years; 95.6% had underlying ulcerative colitis; most common indication for colectomy was medically refractory disease (56.5%). Abdominal pain (82.6%) and bloating (52.2%) were most common presenting symptoms. Most common finding on pouchoscopy was pouch dilatation (81.8%), while barium or gastrografin enemas and MRI/CT mostly revealed dilatation of pouch and/or small bowel. Fourteen (66.7%) patients required some forms of surgery-six patients required pouch excision and three required either pouch redo or revision. Rates of pouch failure and IBD-related 1-year hospitalization were higher among patients managed surgically versus those managed medically (p = 0.007 and 0.024, respectively), while need for escalation of IBD-therapy was comparable between the groups (p = 0.133). No deaths were reported and no patient had recurrence of megapouch. IPAA revision or redo did not lead to more IBD-related morbidity. CONCLUSIONS: Majority of our patients with megapouch required surgery. In selected patients, redo pouch offered cure. Rates of pouch failure and IBD-related 1-year hospitalization were higher among patients managed surgically.

RESUMEN

BACKGROUND: Few studies have investigated surgical outcomes following a colectomy in pediatric patients with ulcerative colitis (UC). PURPOSE: This study aimed to determine long-term outcomes in a large cohort of pediatric patients who underwent proctocolectomy with ileal pouch-anal anastomosis (IPAA) for UC. METHODS: Pediatric patients (<17 years old) who underwent surgery at 12 different hospitals in Japan between May 1979 and March 2015 were included in this study. Information was obtained by the use of a questionnaire survey. RESULTS: There were 113 (53.3%) male and 99 (46.7%) female pediatric patients. The most common indication for elective surgery was failure of medical management, whereas emergency surgery was carried out for fulminant cases. A hand-sewn IPAA was used with a mucosectomy in 112 (52.8%), stapled anastomosis in 93 (43.9%), and not specified in 7 (3.3%) patients. Small bowel obstruction and surgical site infection were the most frequent early postoperative complications (POC), whereas pouchitis, small bowel obstruction, and perianal fistula were frequent late POC. The most common late POC was pouchitis, found in 38 (17.9%) of the patients, whereas pouch failure was noted in 11 patients at the latest follow-up examination. Cumulative pouch survival rate after 10 years was 91.7%. There were no significant differences regarding gender or anastomotic procedure in relation to cumulative pouch survival rate. CONCLUSION: To avoid pouch failure following an IPAA procedure, it is important to recognize that pouchitis or an anal fistula may lead to this condition in pediatric UC patients.
