The effect of proximal and distal small bowel resection on gut hormone release after test meal loading in dogs was studied. Ten beagle dogs were subjected to 50% proximal or distal small bowel resection, and test meal loading was performed after one night fasting to examine gut hormone release. Fasting levels of plasma gastrin were not changed after both proximal and distal resection, but response to test meal was increased at 18 weeks of postoperative period in 50% proximal resection. Postprandial release of plasma GIP was significantly decreased in both proximal and distal resection compared with preoperative period. Postprandial release of enteroglucagon was increased at 4 and 8 weeks in proximal resection. In distal resection, it was increased at 4 weeks but returned to preoperative levels at 8 weeks. Villus height of middle part of the intestine was increased in both proximal and distal resection, and significant change was observed in the duodenal mucosa of proximal resection at 4 weeks. These findings suggest that part of the resection of small bowel influences gut hormone release, and these may play an important role in intestinal adaptation.
