Abstract
We investigated bowel frequency, soiling (continence), and the ability to discriminate between flatus and feces in 12 patients who underwent mucosal proctectomy with ileo-anal anastomosis (IAA) and 6 patients who underwent restorative proctocolectomy with ileo-anal canal anastomosis (IACA). Clinically, IACA patients suffering from soiling were rare, compared with IAA patients. In manometric study, the resting anal pressure of patients with IACA was better than that of those with IAA. Therefore, we considered that soiling (or incontinence) was related to resting anal pressure, and we rcommend IACA for patients with anorectal disorder, rectovaginal fistula, and anal fissure. Preoperative anorectal manometry is important in selecting IAA or IACA for patients with ulcerative colitis.
