[Formation of a blind loop: an unusual bleeding site in chronic intestinal hemorrhage].

The blind-pouch-syndrome may display a variety of symptoms. But it rarely causes intestinal bleeding. In a patient suffering from anemia of chronic intestinal hemorrhage, a blind-pouch was diagnosed through the search for colon polyps. A hemicolectomy with a side-to-side ileocolic anastomosis was performed 30 years ago, but there were no symptoms of maldigestion or malabsorption. The explorative laparotomy revealed an anastomotic stricture with a lot of coproliths in the ileum-blind-pouch. The histological examination of the resected anastomosis showed an unspecific inflammation of the mucosa. Excluding other potential causes of intestinal hemorrhage, this mucosal irritation was presumed to be the bleeding site.
