Transanal Ileal Pouch-Anal Anastomosis for Ulcerative Colitis - A Retrospective Single-Center Study Regarding Anastomotic Leakage and Episodes of Pouchitis in the Long-Term
Abstract Introduction:Colectomy with transanal ileal pouch-anal anastomosis (taIPAA) is a surgical technique that can be used to treat benign colorectal disease. Ulcerative colitis (UC) is the most frequent inflammatory bowel disease (IBD) and although pharmacological therapy has improved, colectomy rates reach up to 15%. Objective of this study was to determine anastomotic leakage (AL) rates and treatment after taIPAA as well as short- and long-term pouch function. Patients and Methods:Data from a prospectively collected database of all patients undergoing taIPAA in our center between March 2015 and August 2019 was analyzed retrospectively. Patients with indications other than UC or with adjuvant chemotherapy following colectomy for colorectal carcinoma were excluded. Results:Of 23 patients undergoing taIPAA in our center 20 patients met the inclusion criteria, with a median age of 36 years at the time of pouch formation. Overall prevalence of AL was 10% with one early (11 days after operation) and one late AL (19 months after operation). In both patients pouches could be preserved with a multimodal approach based on endosponge therapy. Data on short-term pouch function could be obtained in 11 (55.8%) patients and was satisfactory in all cases. In the long-term we observed a pouchitis rate of 57.9% and a pouch failure rate of 5.3%.Conclusion:In our study, taIPAA surgery is a safe procedure and results in good patient outcome. The rate of AL is comparable to transabdominal IPAA. In order to fully evaluate the risks and benefits of taIPAA further studies with larger cohorts of patients are required.
