    Abstract:
    The aim of this study was to compare the functional results of ileo-rectal anastomosis and ileal pouch-anal anastomosis in a group of patients with familial adenomatous polyposis who had conversion of a ileorectostomy into a ileal pouch-anal anastomosis. In 2 cases (8.3 percent), the conversion was impossible because of abdominal desmoid tumors. For the remaining 21 patients, with more than 1 year follow-up, the number of bowel movements per 24 hours was 3.8 +/- 0.2 before and 4.6 +/- 0.3 after conversion. Daytime and nighttime continence and sensation of the need to defecate were unchanged. The number of patients having nocturnal bowel movements were higher after the pouch procedure (40 vs 10.5 percent). After ileorectostomy and after conversion, 89.5 and 80 percent of the patients had good functional results respectively. Ninety percent of the patients said that results were unchanged or improved after the conversion. In familial adenomatous polyposis the functional results of ileal pouch-anal anastomosis are similar to those of ileorectostomy but the first procedure eradicates the risk of rectal cancer. A conversion to ileal pouch-anal anastomosis should to be proposed to patients with ileorectostomy and at high risk for rectal cancer.
