[Total colectomy with proctomucosectomy and ileal passage--animal experiment studies].

Resection of the rectal mucosa, total colectomy and continent anal ileostomy was carried out on 10 dogs. Nine dogs survived. One dog died of small bowel volvulus. A complete morphologic integration of the ileum loop within the rectal muscle tube could be demonstrated angiographically and histologically. Continence was retained.
