AimWith the idea that a small diameter stapler should cause less sphincter trauma, we began to use the 25mm circular stapler to perform ileo-pouch-anal anastomosis (IPAA) and we report our experience.Material Of StudyA retrospective study using a bowel function questionnaire and a quality of life questionnaire has been conducted on a group of patients who underwent IPAA using a 25mm staplerResultsWe performed IPAA using a 25mm circular stapler in 37 patients. Postoperative mortality was nil and morbidity was 27%. One anastomotic stenosis occurred. Long term follow-up information was available on 28 patients. Mean follow-up was 70 months (range 8-177). Mean number of bowel movements was 4.5 (range 2-10, median 4.5) during the day and 0.9 (range 0-10, median 0) at night. Out of 28 patients, 19 (68%) were fully continent and 32% had occasional soiling, no one reported incontinence. All patients except one were able to withold their stool for more than 15 minutes. Daytime pad use was: never 86%, occasionally 3%, frequently 11%; nightime pas use was never 86%, occasionally 7% and frequently 7%. Bowel regulating drugs use was never 82%, occasionally 14%, regularly 4%. Evacuation difficulties were: never 75%, occasionally 21%, frequently 4%.DiscussionOur results compare favourably with the literature, which reports median bowel frequency 6-7.6/24h, 9.4- 33% urgency, 17-44% daytime soiling and 32-61% nighttime soiling.ConclusionsOur results must be considered preliminary but we found the 25-mm stapler safe and adequate to perform IPAA.Key WordsIPAA, Ulcerative Colitis, Stapler, Function.
