[Effect of various methods of resection of the stomach in liberation of cholecystokinin, neurotensin and on pancreatic function].

In a follow up study 19 patients after Billroth-I, 22 patients after Billroth-II-resection and 38 patients after total gastrectomy (23 with Roux-Y-reconstruction and 15 with Longmire-Gütgemann) underwent a stool fat determination and an indirect pancreatic function test with fluorescein dilaurate in serum und urine. In 9 of 19 cases (47.3%) after B-I-resection and 14 of 22 patients (63.5%) after B-II-resection there were pathological results of the PLT-test in urine. After total gastrectomy as well with reconstruction of the duodenal passage as with its exclusion the PLT-test results were pathological in 60% resp. 87%. These results indicate a secondary pancreatic insufficiency following gastric resection.
