Occurrence of peptic ulcer in the gastric tube used for esophageal replacement in adults.

Reported in this paper are two cases of peptic ulcer which developed in the gastric tube used for esophageal replacement following esophagectomy for esophageal tumors in adults. The results of our cases suggest that acid secretion from the mucosa of the gastric tube, in spite of truncal vagotomy and the state of the tube, seems to play important roles in the pathogenesis of peptic ulcer of the gastric tube after esophageal replacement, even though circulatory disturbances, due to postoperative irradiation and gastric tube formation, have been suspected as the cause. Therefore, in those cases of gastric tube stasis, surgical drainage of the gastric tube should be performed.
