Medical Therapies for Prevention and Treatment of Inflammatory Pouch Disorders-A Systematic Review and Meta-Analysis.

Pouchitis and Crohn's-like disease of the pouch (CLDP) are common in patients who undergo ileal pouch anal anastomosis for ulcerative colitis. We conducted separate systematic reviews to evaluate the effectiveness of available interventions to prevent and treat pouchitis and CLDP. Through systematic literature reviews, we identified studies that evaluated the effectiveness of probiotics, antibiotics, 5-aminosalicylates, nonsystemic oral corticosteroids, and advanced therapies for prevention and treatment of pouchitis and CLDP for meta-analysis. Primary outcomes were occurrence of pouchitis for pouchitis prevention and clinical response for pouchitis and CLDP treatment. We estimated the relative effectiveness of these interventions using the existing placebo response rates or hypothetical spontaneous improvement rates derived from clinical trials of pouchitis, ulcerative colitis, and Crohn's disease. Probiotics were effective for primary (relative risk [RR] 0.18; 95% confidence interval [CI] 0.05-0.62) and secondary prevention (RR 0.17; 95% CI 0.09-0.34) of pouchitis. Antibiotics were effective for treatment of acute and chronic pouchitis (12 cohorts; RR 1.67; 95% CI 1.34-2.01; response rate 65%; 95% CI 52-75) with ciprofloxacin and metronidazole-based regimens being more effective than rifaximin. Advanced therapies were effective for treatment of chronic antibiotic-refractory pouchitis (31 cohorts; RR 1.71; 95% CI 1.28-2.56; response rate 50%; 95% CI 43-57) and CLDP (10 cohorts; RR 2.49; 95% CI 1.87-3.73; response rate 74%; 95% CI 68-79) without significant difference between classes. Multiple medical interventions are effective for prevention and treatment of pouchitis and CLDP. Given the overall low quality of data, further research is needed to confirm these findings.

Acute Pouchitis is Common in Pregnant and Postpartum Women.

The impact of pregnancy on the development of pouchitis in women who have undergone total proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis is poorly understood. This was a retrospective study of women with ulcerative colitis who underwent total proctocolectomy with ileal pouch anal anastomosis and subsequently became pregnant at Mount Sinai Hospital. The primary outcome was acute pouchitis during pregnancy or the postpartum period defined as symptoms of increased stool frequency and urgency treated with antibiotics. A total of 44 women with 63 pregnancies and complete data were identified. Acute pouchitis occurred in 14 pregnancies (22.2%) in 12 women and in the postpartum period of 10 pregnancies (15.9%) in 9 women. Acute pouchitis occurred more frequently in women with a history of acute pouchitis immediately before, during, or after pregnancy. Acute pouchitis was common during pregnancy and the postpartum period, likely due to microbial shifts. Although not statistically significant, these results provide insight into the impact of pregnancy on the risk of pouchitis and establish the framework for preconception counseling that focuses on prevention and management of pouchitis during pregnancy.

Management of Anastomotic Leaks in Ileal Pouch Anal Anastomosis for Ulcerative Colitis.

Anastomotic leaks remain a dreaded complication after ileal pouch anal anastomosis (IPAA). Their impacts can be devastating, ranging from an acute leak leading to postoperative sepsis to chronic leaks and sinus tracts resulting in long-term pouch dysfunction and subsequent pouch failure. The management of acute leaks is intricate. Initial management is important to resolve acute sepsis, but the type of acute intervention impacts long-term pouch function. Aggressive management in the postoperative period, including the use of IV fluids, broad-spectrum antibiotics, and operative interventions may be necessary to preserve pouch structure and function. Early identification and knowledge of the most common areas of leak, such as at the IPAA anastomosis, are important for guiding management. Long-term complications, such as pouch sinuses, pouch-vaginal fistulas, and diminished IPAA function complicate the overall survival and functionality of the pouch. Knowledge and awareness of the identification and management of leaks is crucial for optimizing IPAA success.

Transanal ileal pouch anal anastomosis for ulcerative colitis in children and adults: a systematic review and meta-analysis.

The incidence of pediatric onset ulcerative colitis (UC) is increasing, with increasing rate of children eventually requiring surgical treatment. Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the preferred surgical treatment. Although transanal IPAA (ta-IPAA) is becoming widely accepted for adult UC patients, data regarding this procedure in children are scarce. Nevertheless, some adult publications also include patients under 18years old. This systematic review and meta-analysis aimed to summarize surgical and functional outcomes following ta-IPAA, and extract conclusion regarding pediatric UC patients. PubMed, Cochrane Library databases, Embase, Web of science and Google Scholar databases were searched, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines. The final search was updated in April 2022. Four comparative cohorts (n = 868) and 11 non-comparative case series (n = 241) were included. Six reports included children. Anastomotic leak, complications, operative time, conversion rate, length of stay and functional outcomes were examined. A total of 1103 patients, ranging 9-79years were included in this review. We found no difference in risk for anastomotic leak (OR 1.36, 95% CI 0.46-4.06), minor and major complications (OR 0.92, 95% CI 0.48-1.76 and OR 0.78 95% CI 0.36-1.69, respectively) comparing ta-IPAA to transabdominal IPAA. Short- and long-term follow-up showed satisfying functional outcomes and quality of life. Our review suggests that ta-IPAA is not inferior to transabdominal IPAA. Implementation of this method in children is technically feasible due to familiarity with the dissection plane. Long-term functional outcomes and quality of life are paramount in the pediatric population and should be particularly investigated. Multicenter prospective studies are required to investigate pediatric UC patients undergoing ta-IPAA.

Long Distance Between the Superior Mesenteric Artery Root and Bottom of the External Anal Sphincter Is a Risk Factor for Stoma Outlet Obstruction After Total Proctocolectomy and Ileal-Pouch Anal Anastomosis for Ulcerative Colitis.

BackgroundStoma outlet obstruction (SOO) is much more common after total proctocolectomy (TPC) and ileal‐pouch anal anastomosis (IPAA) for ulcerative colitis (UC) compared to after rectal surgery for cancer. Few prior reports have evaluated anatomical risk factors for SOO. In this study we aimed to clarify the risk factors for SOO after IPAA, focusing on the anatomical perspective.MethodsThis study included 68 UC patients who underwent IPAA with diverting ileostomy. These cases were analyzed based on clinicopathological factors and computed tomography (CT)‐based anatomical factors.ResultsSOO was identified in 18 patients (26.5%). We compared this SOO group with the non‐SOO group. The two groups significantly differed in sex distribution, and patients in the SOO group tended to have a longer postoperative hospital stay. Regarding surgery‐related factors, patients who underwent two‐stage surgery and experienced high‐output syndrome tended to develop SOO. Analysis of anatomical risk factors revealed that SOO was more common in patients with a longer distance between the root of their superior mesenteric artery and the bottom of the external anal sphincter (rSMA‐bEAS). This tendency remained significant even with adjustment for patient height. In multivariate analyses, adjusted rSMA‐bEAS (>191.0 mm/m) and male sex were independent risk factors associated with SOO.ConclusionA long rSMA‐bEAS distance suggests that the mesentery is likely to be under tension. In such cases, surgeons should endeavor to avoid tension in the mesentery as much as possible.

Defecation Function After Laparo-Assisted Restorative Proctocolectomy with Ileal Pouch Anal Anastomosis for Ulcerative Colitis.

Background: Defecation status is an important determinant of quality of life. Previous studies showed that postoperative defecation disorders occurred after open surgery for ulcerative colitis (UC), but few have investigated defecation status after laparo-assisted surgery. The added precision and magnification provided with laparo-assisted surgery should lead to less damage to the anal sphincter muscle. This study investigated defecation function after a laparo-assisted restorative proctocolectomy (RPC) with ileal pouch anal anastomosis (IPAA). We also clarified factors that worsened defecation status. Methods: This retrospective study included 57 patients who underwent laparo-assisted RPC with IPAA for UC from January 2000 to May 2019. At 1 year after surgery, functional outcomes were evaluated with the Kirwan classification and Wexner score. Risk factors for poor defecation status were investigated with multiple regression. Results: At 1 year after surgery, the median Kirwan classification score was 2 and the median Wexner score was 8. Defecation disorder was observed in 19 (33.3%) patients, according to the Kirwan classification, and 15 (26.3%) patients, according to the Wexner score. Hand-sewn IPAA was associated with defecation disorder (P = .04), evaluated with the Kirwan classification. Hand-sewn IPAA (P = .01), older age (P = .03), high body mass index (P = .04), and the surgical indication (cancer/dysplasia; P = .03) were significantly associated with defecation disorder, evaluated with the Wexner score. The multivariable analysis showed that hand-sewn IPAA was an independent risk factor (P = .049; odds ratio: 4.99; 95% confidence interval: 1.0-28.39). Conclusions: We found that hand-sewn IPAA was a risk factor for defecation disorders after laparo-assisted RPC for UC.

Rectovaginal fistula: Risk factors for failure after graciloplasty-A bicentric retrospective European study of 61 patients.

Graciloplasty (GP) is indicated in the case of recurrent rectovaginal fistula (RVF) after failure of previous local treatments. The aim of this study was to assess risk factors for GP failure performed for RVF. This is a retrospective study based on a prospective database on GP, coming from two expert centres. Sixty-one patients undergoing a first GP for RVF (n=51) or ileal-vaginal fistula after ileal pouch anal anastomosis (n=10), with a mean age of 42years (range 24-72), were analysed. After a mean follow-up of 56±48months (range 1-183), failure of GP (considered as persistent stoma and/or clinical RVF) was noted in 24/61 patients (39%). The failure rate was 43% (13/30) in the case of Crohn's disease, 38% (3/8) in the case of ileal-vaginal fistula after ileal pouch anal anastomosis for ulcerative colitis, 30% (3/10) in the case of obstetrical RVF, 33% (1/3) in the case of post radiotherapy RVF and 40% (4/10) for other causes (not significant). Two risk factors for failure of GP were found on univariate analysis: (1) absence of postoperative antibiotic prophylaxis-only 3/24 (13%) patients with failure of GP received postoperative antibiotic prophylaxis versus 18/37 (49%) patients with success of GP (P=0.0053); (2) postoperative perineal infection-11/23 (48%) with failure of GP developed postoperative perineal infection versus only 4/37 (10%) patients with success of GP (P=0.0021). Failure of GP for RVF is observed in approximately 40% of the patients whatever the aetiology of the fistula. A reduced failure rate was associated with systematic postoperative antibiotic prophylaxis.

Early ileal pouch anal anastomosis for ulcerative colitis in children: Similar outcome to delayed pouch construction despite higher comorbidity

BackgroundChildren with ulcerative colitis (UC) may undergo a staged approach for restorative proctocolectomy and ileal pouch anal anastomosis (IPAA). Previous studies in adults suggest a decreased morbidity with delayed pouch creation, but pediatric studies are limited. We compared outcomes for delayed versus early pouch construction in children. MethodsPatients with UC undergoing IPAA were selected from the National Surgical Quality Improvement Program Pediatric database from 2012 to 2018. Patients were categorized as early (2-stage) or delayed (3-stage) pouch construction based on Current Procedural Terminology codes. Our primary outcome was any adverse event. We used a multivariable logistic regression model to assess the relationship between timing of pouch creation and adverse events. ResultsWe identified 371 children who underwent IPAA: 157 (42.3%) had early pouch creation and 214 (57.6%) had a delayed pouch. Those with an early pouch creation were more likely to have exposure to immunosuppressants (11% vs. 5%, p = 0.017) and steroids (30% vs. 10%, p < 0.001) at the time of surgery. After controlling for patient characteristics, there were no significant differences in adverse events between the two groups. ConclusionsChildren undergoing early pouch creation have increased exposure to steroids and immune suppressants; nevertheless, no differences in adverse events were identified. Level of evidenceII

Postoperative functional outcomes and complications of partially intraanal canal anastomosis in stapled ileal pouch anal anastomosis for ulcerative colitis.

For ulcerative colitis (UC), stapled ileal pouch anal anastomosis (IPAA) reportedly results in better bowel function than does IPAA with mucosectomy. However, a potential cancer risk in the remnant mucosa has been observed. The clinical results of IPAA by double stapling technique (DS-IPAA) in which the anastomotic line was on the dentate line at posterior wall and the top of anal canal at anterior wall ("Partially intraanal canal anastomosis": PICA) to reduce the remnant mucosa were evaluated. Clinical results of PICA were retrospectively compared with those by DS-IPAA with anastomosis at above the anal canal on 1year after open surgery. Of 211 UC cases that underwent DS-IPAA, 146 cases (69%) with PICA who were confirmed by the squamous epithelium on the posterior part of the distal donuts were included. Sixty-five cases with anastomosis above the anal canal were evaluated as the control. One stage surgery underwent in 95% of PICA and 93% of control. One year after surgery, each group had six bowel movements daily. Nighttime evacuation was found in 16% of PICA and in 20% of control. Soiling was found in 1% of PICA and 4.8% of control. After one stage operation, anastomotic leakage that needed ileostomy was observed in 0.7% of PICA and 3% of control. Partially intraanal canal anastomosis (PICA) can reduce anal canal mucosa with the same postoperative bowel function and complication rate as DS-IPAA above the anal canal. This procedure may be feasible for UC patients who can tolerate this procedure in terms of decreasing postoperative cancer risk.

Short-term Results After Totally Robotic Restorative Total Proctocolectomy With Ileal Pouch Anal Anastomosis for Ulcerative Colitis

In this study, we aimed to present our initial experience on totally robotic total restorative proctocolectomy in ulcerative colitis (UC) patients. Patients undergoing a totally robotic restorative total proctocolectomy with ileal J-pouch anal anastomosis for UC between January 2015 and November 2017 were included. The da Vinci Xi was used for the operations. Patient demographics, perioperative and short-term operative outcomes were evaluated. Ten patients were included. The median operative time was 380 minutes(range, 300 to 480 min). The median blood loss was 65 mL (range, 5 to 400 mL). No conversion to open surgery was needed. The median time to flatus was 1 day (range, 1 to 2) and length of stay was 6 (4 to 12) days. Short-term complications (≤30 d) were superficial wound infection (n=3), anal bleeding (n=1), pouchitis (n=1). No mortality was observed during the study period. Our study, which is the largest series so far, reveals that totally robotic restorative proctocolectomy is a safe and feasible option for the surgical treatment of UC.

Reliability among central readers in the evaluation of endoscopic disease activity in pouchitis

Pouchitis is a common adverse event after proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis. Evaluation of pouchitis disease activity and response to treatment requires use of validated indices. We assessed the reliability of items evaluating endoscopic pouchitis disease activity. Twelve panelists used a modified RAND appropriateness methodology to rate the appropriateness of items evaluating endoscopic pouchitis disease activity derived from a systematic review and also identified additional potential endoscopic items based on expert opinion. Four central readers then evaluated 50 pouchoscopy videos in triplicate, in random order. Intra- and inter-rater reliability for each item was assessed by calculating and comparing intraclass correlation coefficients (ICCs). A Delphi process identified common sources of disagreement among the readers. Ten existing endoscopic items were identified from the systematic review and an additional 7 exploratory items from the panelists. ICCs for inter-rater reliability were highest for the existing item of pouch ulceration (.72; 95% confidence interval [CI], .60-.82) and for the exploratory item of ulcerated surface in the pouch body (.67; 95% CI, .53-.75). Inter-rater reliability for all other existing and exploratory items was "moderate" (ICC< .60). The item "ulcerated surface in the pouch body" demonstrated the best correlation with a global evaluation of lesion severity (r= .80; 95% CI, .73-.85). Substantial reliability was observed only for the endoscopic items of ulceration and ulcerated surface in the pouch body. Future studies should assess responsiveness to treatment in the next stage toward development of an endoscopic pouchitis disease activity index.

Spinal epidural abscess: a rare complication of ulcerative colitis after ileal pouch anal anastomosis.

BackgroundSpinal epidural abscess is a rare condition with high morbidity and mortality, for which a delay in diagnosis and treatment can lead to irreversible neurologic deficit or even death. Although patients with spinal epidural abscess have systemic predisposing immunocompromised conditions, spinal intervention, or trauma, this condition has been reported as a result of perforation or fistulization arising from inflammatory bowel disease. We describe herein a rare case of spinal epidural abscess as a complication of ileal pouch anal anastomosis.Case presentationA 37-year-old man who had previously undergone restorative proctocolectomy and ileal pouch anal anastomosis for ulcerative colitis presented with complaints of persistent low-grade fever and lumbago with unusual sensation in the lower legs. After evaluation by Gastrografin contrast radiography, computed tomography, and magnetic resonance imaging, he was diagnosed with a spinal epidural abscess extending from L5 to S1. In addition, the abscess communicated with the ileal pouch. He underwent surgical drainage of the abscess, excision of the fistula, and defunctioning ileostomy. Although a second operation for drainage was required for residual presacral abscess, there was no sign of recurrence of the spinal epidural abscess. He eventually was able to close his stoma.ConclusionsAlthough spinal epidural abscess is a rare complication, one should take this condition into account when patients complain of back pain or neurologic symptoms of the lower extremities, given the possibility of fistulous communication between the ileal pouch and spine.

Complications in colorectal surgery

Colorectal pediatric surgery is a diverse field that encompasses many different procedures. The pullthrough for Hirschsprung disease, the posterior sagittal anorectoplasty for anorectal malformations including complex cloaca reconstructions and the ileal pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis present some of the most technically challenging procedures pediatric surgeons undertake. Many children prevail successfully following these surgical interventions, however, a small number of patients suffer from complications following these procedures. Anticipated postoperative problems are discussed along with medical and surgical strategies for managing these complications.

Sexuality and fertility outcomes after hand sewn versus stapled ileal pouch anal anastomosis for ulcerative colitis

BackgroundIleal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. MethodsAll UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. ResultsA total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). ConclusionsIn this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA.
