[Changes in acid producing and motor-evacuatory functions of the stomach after median gastric resection]

Changes in the acid production and motility of a gastric stump in 108 patients after mediogastric pylorus-and-antrum preserving resection performed for ulcer disease of the stomach (72 patients) and duodenum (36) were studied. In most patients, 1-3 years later, a weak acid and moderate acid reaction was noted in the gastric body. Complete restoration of motor-evacuatory function of the stomach and duodenum occurred within 1 year.
