Outcomes after transanal proctectomy with ileal pouch–anal anastomosis in adolescents

Purpose The aim of this study was to describe our initial surgical and functional outcomes of transanal ileal pouch anastomosis (Ta-IPAA) in adolescents. Methods A total of 16 adolescents’ age ≤ 19 underwent consecutive Ta-IPAA on the indication ulcerative colitis (UC) or familiar adenomatous polyposis (FAP), between January 2018 and September 2022. Primary outcomes were postoperative complications. Secondary outcomes were conversion rates, intraoperative complications, length of hospital stay (LOS), morbidity within 30 days, surgical characteristics, and functional outcomes. Results Thirteen adolescents with UC and three with FAP underwent Ta-IPAA. The median age of UC patients was 16. They had a colectomy on the indication UC followed by a Ta-IPAA. Median operating time was 247 min, and there were no conversion or intraoperative complications. Median LOS was 7 days. No anastomotic leakage was observed, and three patients had complications within the first 30 days. Three had late complications. The median bowel movements were 5, and 50% had bowel movements during the night. Three children were operated on the indication FAP with proctocolectomy and Ta-IPAA. There were no conversion or intraoperative complications, and the median bowel movements was 4. Conclusion Ta-IPAA approach in children seems to be feasible, safe and offers acceptable functional results.
