Gastric emptying and sieving of solid food and pancreatic and biliary secretions after solid meals in patients with nonresective ulcer surgery.

This study was undertaken to compare with previously published findings in normal subjects and subjects after truncal vagotomy and antrectomy the effects of nonresective ulcer surgery on (a) gastric emptying, grinding, and sieving of solid food and on (b) pancreatic and biliary secretions. Six subjects with proximal gastric vagotomy and 7 subjects with truncal vagotomy with pyloroplasty were studied using a previously validated indicator perfusion system with its aspiration port placed in the proximal jejunum. All subjects were given a meal of 30 g of 99mTc-liver, 60 g of beefsteak, and 100 ml of H2O.
