[Resection of the valvula bauhini and its effect on the metabolism. An experimental study in animals (author's transl)].

In animal experiments (20 mongrel dogs) malabsorption was induced by resection of 100 cm ileum. Subsequently the influence of the ileocoecal valve (Valvula Bauhini) in absorption was studied. In one group of animals intestinal continuity was reestablished by ileoileostomy, in a second by ileocolostomy. The results of the absorption studies were compared with a healthy control group. After ileoileostomy animals do not lose weight, serum cholesterol and protein remain normal. Oral tolerance tests with Triolein-iodine-131 and Cyanocobalamine show results identical with those of the control group. After ileocolostomy all these parameters are lowered--partially to a pathological level. It is concluded that in all operations in the area of the terminal ileum and colon the Valvula Bauhini should be retained if possible.
