[Animal experiments in stagnant loop syndrome].

Using the perfusion technique, the absorption of water, sodium, and glucose was studied in a partial occlusion of the intestine. In this study we investigated the mucosal enzyme, the metabolic changes of the small bowel wall, and the morphology of the mucosa. The reason for the decreased absorption of glucose, sodium, and water in the prestenotic phase may be the increased proliferation of the mucosa. The decreased absorption of the glucose, sodium and water in the poststenotic phase may be caused by an atrophy of the mucosa.
