title: Postoperative gastric motility, secretory function, and pre- and postoperative carbohydrate metabolic states in esophageal cancer patients.
abstract: This study was undertaken to assess postoperative gastric motility and gastric acid secretion, and pre- and postoperative carbohydrate metabolism in patients with esophageal cancer. The gastric motility was compared among 3 different reconstruction routes in 26 patients who were divided into 2 groups according to the duration of postoperative follow-up; group A, 3 months or less; and group B, 18 months or more. The routes used for subtotal resection of the stomach were the posterior mediastinal, retrosternal, and subcutaneous routes. All patients showed positive resting pressure in the esophagus, but peristaltic waves did not reach the gastric tube at dry swallowing in any patients and peristaltic waves appeared after eating pudding only in 1 patient in group B. The resting pressure and gastric emptying time were similar among reconstruction routes, but the incidence and amplitude of metoclopramide (MCP)-induced peristaltic waves were significantly higher in group B than in group A. Furthermore, 24-h intragastric pH monitoring of gastric secretion in a group of 9 patients revealed individual variation in gastric secretion. Some patients showed high acidity soon after operation, suggesting the need for prophylactic treatment for preventing gastric ulcer. Postoperatively, postprandial serum gastrin levels were significantly higher than preoperative levels. In the other group of 11 patients tested, preoperative and postoperative carbohydrate metabolism were not significantly different. Postoperatively, carbohydrate metabolism recovered to preoperative levels after a transient decrease. These results demonstrated that postoperative motility improved over time although no difference was found among the 3 reconstruction routes used.
