Extensive Disease and Exposure to Multiple Biologics Precolectomy Is Associated with Endoscopic Cuffitis Post-Ileal Pouch-Anal Anastomosis in Patients With Ulcerative Colitis

INTRODUCTION

To better inform the risk of cuffitis in patients with ulcerative colitis (UC), we aimed to identify its occurrence and associated precolectomy factors in a large multicenter cohort of patients who underwent restorative proctocolectomy (RPC) with stapled ileal pouch-anal anastomosis (IPAA).

METHODS

This study was a retrospective cohort analysis of individuals diagnosed with UC or indeterminate colitis who underwent RPC with IPAA for refractory disease or dysplasia at Mount Sinai Hospital or the University of Chicago followed by at least 1 pouchoscopy with report of the pouch-anal anastomosis. The primary outcome was cuffitis defined as ulceration of the cuff as reported in each pouchoscopy report.

RESULTS

The pouch-anal anastomosis was mentioned in the pouchoscopy reports of 674 patients, of whom 525 (77.9%) had a stapled anastomosis. Among these, cuffitis occurred in 313 (59.6%) patients a median of 1.51 (interquartile range 0.59-4.17) years after final surgical stage. On multivariable analysis, older age (hazard ratio [HR], 1.01; 95% confidence interval [CI], 1.01-1.02), extensive disease (HR, 1.34; 95% CI, 1.01-1.78), exposure to biologics before colectomy (HR, 2.51; 95% CI, 1.93-3.27), and exposure to at least 2 or more biologics before colectomy (HR, 2.18; 95% CI, 1.40-3.39) were significantly associated with subsequent cuffitis.

CONCLUSIONS

In this multicenter study of patients who underwent RPC with stapled IPAA and at least 1 follow-up pouchoscopy, cuffitis occurred in approximately 60% and was significantly associated with extensive disease and exposure to multiple biologics precolectomy.

Preoperative Use of Multiple Advanced Therapies Is Not Associated With Endoscopic Inflammatory Pouch Diseases

BACKGROUND

Patients with an ileal pouch-anal anastomosis (IPAA) can experience pouch inflammation postoperatively. The use of antitumor necrosis factor (anti-TNF) biologics may be associated with pouch inflammation, but limited data exist on the impact of multiple advanced therapies on development of subsequent pouch inflammation. The aim of this study was to assess for an association between preoperative use of multiple advanced therapies and risk of endoscopically detected inflammatory pouch diseases (EIPDs).

METHODS

We performed a retrospective analysis of ulcerative colitis (UC) and indeterminate colitis (IBDU) patients who underwent an IPAA at a quaternary care center from January 2015 to December 2019. Patients were grouped based on number and type of preoperative drug exposures. The primary outcome was EIPD within 5 years of IPAA.

RESULTS

Two hundred ninety-eight patients were included in this analysis. Most of these patients had UC (95.0%) and demonstrated pancolonic disease distribution (86.1%). The majority of patients were male (57.4%) and underwent surgery for medically refractory disease (79.2%). The overall median age at surgery was 38.6 years. Preoperatively, 68 patients were biologic/small molecule-naïve, 125 received anti-TNF agents only, and 105 received non-anti-TNF agents only or multiple classes. Ninety-one patients developed EIPD. There was no significant association between type (P = .38) or number (P = .58) of exposures and EIPD, but older individuals had a lower risk of EIPD (P = .001; hazard ratio, 0.972; 95% confidence interval, 0.956-0.989).

CONCLUSION

Development of EIPD was not associated with number or type of preoperative advanced therapies.

Efficacy and Safety of Upadacitinib in the Treatment of Chronic Pouchitis, Cuffitis, and Crohn's Disease of the Pouch

Upadacitinib has shown efficacy in the treatment of moderate-to-severe ulcerative colitis and Crohn's disease (CD). The use of upadacitinib in the treatment of chronic antibiotics-refractory pouchitis (CARP), as well as CD of the pouch, has not been previously reported. We treated a series of 6 patients with CARP or CD of the pouch with a minimal 6 weeks of upadacitinib. The patients showed minimal or no significant improvement in clinical and endoscopic presentations. Our findings warrant further study to validate the efficacy and safety of upadacitinib in the treatment of CARP or CD of the pouch.

Tofacitinib for the Treatment of Pouch-Related Disorders: A Case Series

In this case series, 6 patients with chronic pouchitis (n = 3), cuffitis (n = 2), or Crohn’s-like disease of the pouch (n = 1) were treated with tofacitinib. One patient achieved clinical response; however, all patients ultimately discontinued therapy due to nonresponse or adverse events.

The Reliability and Accuracy of Endoscopic Items and Scores Used in the Assessment of the Ileoanal Pouch and Cuff

BACKGROUND AND AIMS

Currently used endoscopic items for the assessment of pouchitis and cuffitis have deficiencies in reliability and validation. We assessed the reliability and accuracy of new endoscopic items for pouchitis and of the Ulcerative Colitis Endoscopic Index of Severity [UCEIS] for cuffitis.

METHODS

Three new endoscopic items were assessed and included in the Monash pouchitis endoscopic subscore: bleeding [absent/contact/spontaneous]; erosions [absent/<10/≥10]; and ulceration [absent/<10%/≥10%]. Three raters evaluated 44 pouchoscopy videos in duplicates, in random order. Intra- and inter-rater reliability of all endoscopic items and UCEIS were assessed. Clinical and histological pouchitis disease activity index [PDAI] subscores were also assessed and faecal calprotectin was measured.

RESULTS

All three Monash endoscopic items had substantial intra-rater reliability with intraclass correlation coefficients [ICCs] >0.61 [95% CI >0.61], compared with only ulcers from the currently used PDAI endoscopic subscore, but inter-rater reliability was only substantial for ulceration and no better than those of the currently used endoscopic items. The Monash endoscopic subscore had a strong positive correlation with the reference standard global endoscopic lesion severity r = 0.80 [95% CI 0.80-0.80] and the reference standard PDAI endoscopic subscore r = 0.70 [95% CI 0.67-0.73], which was higher than the correlation observed for the currently used PDAI endoscopic subscore. The UCEIS had substantial intra-rater reliability, but only fair inter-rater reliability and poor diagnostic performance for cuffitis.

CONCLUSIONS

The Monash endoscopic items, and endoscopic subscore they generate, have enhanced overall performance compared with the currently used PDAI items and subscore. Further validation and responsiveness to change in disease state are indicated.

Inflammatory Pouch Conditions Are Common After Ileal Pouch Anal Anastomosis in Ulcerative Colitis Patients

BACKGROUND

Total proctocolectomy (TPC) with ileal pouch anal anastomosis (IPAA) is the gold standard surgery for ulcerative colitis (UC) patients with medically refractory disease. The aim of this study was to report the rates and risk factors of inflammatory pouch conditions.

METHODS

This was a retrospective review of UC or IBD unspecified (IBDU) patients who underwent TPC with IPAA for refractory disease or dysplasia between 2008 and 2017. Pouchoscopy data were used to calculate rates of inflammatory pouch conditions. Factors associated with outcomes in univariable analysis were investigated in multivariable analysis.

RESULTS

Of the 621 patients more than 18 years of age who underwent TPC with IPAA between January 2008 and December 2017, pouchoscopy data were available for 386 patients during a median follow-up period of 4 years. Acute pouchitis occurred in 205 patients (53%), 60 of whom (30%) progressed to chronic pouchitis. Cuffitis and Crohn's disease-like condition (CDLC) of the pouch occurred in 119 (30%) patients and 46 (12%) patients, respectively. In multivariable analysis, female sex was associated with a decreased risk of acute pouchitis, and pre-operative steroid use and medically refractory disease were associated with an increased risk; IBDU was associated with chronic pouchitis; rectal cuff length ≥2 cm and medically refractory disease were associated with cuffitis; age 45-54 at colectomy was associated with CDLC. Rates of pouch failure were similar in chronic pouchitis and CDLC patients treated with biologics and those who were not.

CONCLUSIONS

Inflammatory pouch conditions are common. Biologic use for chronic pouchitis and CDLC does not impact the rate of pouch failure.

Outcome after ileal pouch-anal anastomosis in ulcerative colitis patients: experience during a 27-year period

BACKGROUND

No previous study describes the postoperative outcome and functional results after ileal pouch-anal anastomosis (IPAA), performed in ulcerative colitis by the same surgical team with the different anastomotic techniques adopted in a 27-year period.

METHODS

Prospectively, consecutive 333 ulcerative colitis patients operated adopting different IPAA techniques during the open surgery period 1984-2011 were enrolled. IPAA was performed using single stapling (SS) technique in 38 patients, double stapling (DS) technique in 235 patients (TIA stapler 42 patients, Endo-GIA 131 patients, Contour 62 patients) and handsewn IPAA in 60 patients.

RESULTS

Statistically different early and late complications were recorded among the different IPAA techniques. A lower frequency of daily and nocturnal defecations and a higher level of continence were observed in the DS-IPAA compared to handsewn IPAA. The distance between the anastomotic line and the anal verge was significantly lower in DS Endo-GIA or DS Contour groups than in the DS TIA and SS. In SS IPAA group, 31.6% developed cuffitis compared to 14.4% belonging to DS group, at a mean follow-up of 140.4 months.

CONCLUSIONS

Technical improvements changed the IPAA technique. Stapled IPAA is characterized by better functional outcome than handsewn IPAA. DS Endo-GIA and Contour IPAA are followed by lower risk of cuffitis.
