[Functional diagnosis of intestinal absorption in gastroenterology surgery].
Clinical tests for measuring the intestinal absorption in abdominal surgery, especially surgery of the GI-tract, are of great importance. The absorption of the proximal small intestine can be investigated via a modified D-xylose-test. The distal small intestine may be studied by using the vitamin-B12 urinary excretion test. The bacterial overgrowth syndrome and the absorption of bile salts can be diagnosed on the basis of a 14C-glykocholate test.
