Internal anal sphincter function after total abdominal colectomy and stapled ileal pouch-anal anastomosis without mucosal proctectomy.
A comparison, based on results from anal manometry and continence, was made between eight patients after circular stapled ileal J-pouch-anal anastomosis without mucosectomy (Js) and seven patients after endoanal mucosal proctectomy and hand-sewn ileal pouch-anal anastomosis (Jm). The mean and range from ileostomy closure were 3.5 months (1.5 to 12) and 21.7 months (13 to 32), respectively. The mean maximum resting pressure (MRP) ( +/- SEM and range) was 81.3 mm Hg ( +/- 6.0 and 61 to 112.5) and 50.0 mm Hg ( +/- 6.2 and 17 to 62.5), respectively, for the Js and Jm groups (P less than .003). None of the Js patients experienced leakage or wore a pad, while in the Jm group 14 percent experienced minor leakage during the day and 28 percent at night. Seventy-one percent of the Jm group wore a pad at some point. Anal sphincter resting pressures and continence were better in the Js group. The improvement in MRP resulted from avoidance of injury to the internal and sphincter during dilatation and mucosectomy and the maintenance of a normal anal canal that allowed for proper closure.
