[Intestinal side-to-side anastomosis as a cause of iron deficiency anemia].

Analysis of 9 cases showed that diagnostic laparotomy is advisable in patients with side-to-side anastomosis of the small intestine who are suffering from chronic posthemorrhagic iron deficiency anemia and in whom the source of bleeding is not identified by methods of clinical examination. Improper techniques of the creation of a side-to-side anastomosis+ lead to the formation of blind pouches with the development of ulcers and erosions on the mucous membrane, which are the source of the bleeding. Resection of the anastomosis and subsequent establishment of an end-to-end anastomosis removes the source of the bleeding and comprises etiopathogenetic treatment of iron deficiency anemia in these patients.
