Abstract
Gastric emptying of a solid meal and serum gastrin concentration were studied in 26 patients with duodenal ulcer disease before and after parietal cell vagotomy (PCV), selective gastric vagotomy with drainage (SGV + D), or parietal cell vagotomy with drainage. PCV had no significant effect on gastric emptying rate, whereas emptying was significantly delayed after SGV + D. The integrated gastrin output 60 to 300 min after the test meal was insignificantly altered after PCV, but significantly increased after SGV + D. It is concluded that the drainage procedure did not normalize the disturbed gastric emptying after SGV. The prolonged hypergastrinemia period after food stimulation may reflect stasis.
