Abstract
Emptying of liquids from the stomach was studied in 19 patients who had had a vagotomy and pyloroplasty and the results compared with 12 patients with duodenal ulcers and 9 patients with normal upper gastrointestinal tracts. The patterns of gastric emptying after vagotomy and pyloroplasty was found to consist of a very rapid initial emptying phase followed by emptying at a rate rather faster than in the other two groups. There was no difference in the gastric emptying of patients with duodenal ulcer and those with a normal gastrointestinal tract. Patients who complained of postprandial fullness and dumping after vagotomy and pyloroplasty had extremely rapid initial gastric emptying, more than half the test solution leaving the stomach almost immediately. Three patients who had postoperative gastric ulcers, 2 patients with vomiting since operation and 1 with postvagotomy persistent diarrhea showed a starting index and half-life similar to those of asymptomatic postoperative patients and only minor differences in the emptying time.
