Abstract
The histological changes and gastric function alterations in 19 patients who had intrathoracic stomach replacement following esophagectomy were studied. Atrophic gastritis was noted in 13 of the 19 patients. The mechanical response of the stomach to distention by food was largely retained. The basal and maximal acid output was reduced markedly, and the serum gastrin was elevated. An association between the degree of gastritis, the percentage of gastric motility at rest, and acid secretion is demonstrated. These changes are consistent with patients with duodenal ulcer following vagotomy and dyloroplasty. Postprandial elevation in serum gastrin was noted in patients with or without vagotomy. The lack of significant difference in integrated gastrin response suggests that the vagus may not be important in the control of postprandial gastrin release.
