A prospective cohort study assessed the anal defecatory function in ulcerative colitis patients undergoing total proctocolectomy (tpc) followed by ileal pouch-anal anastomosis (ipaa). The study included 20 consecutive patients who were evaluated using high-resolution anorectal manometry. After surgery, the mean number of bowel movements decreased significantly, symptoms of fecal incontinence were eliminated, and the quality of life improved. Furthermore, there were no significant changes in anal resting and squeeze pressures, indicating that the anorectal function remained intact after the procedure.
