Ileo-anal anastomosis with ileum reservoir

Ileo-anal anastomosis with an ileal pouch is a reasonable alternative for patients with ulcerative colitis and adenomatous polyposis coli. The type of the reservoir, the length of the rectal cuff and the level of the anastomosis are still topics of discussion. This operation was performed in 41 patients. A modified J-reservoir (B-reservoir) was constructed in 34 patients in an attempt to improve the function of the neorectum. Twenty patients underwent inter-sphincteric freeing of the rectum and subsequent resection without leaving a rectal cuff. Although this procedure is associated with a considerable morbidity, the ultimate result is satisfactory.
