A CASE OF EARLY GASTRIC CACER DEVELOPED IN THE REMNANT STOMACH AND TREATED BY ESD SUCCESSFULLY

Abstract

Gastric cancers occasionally develop in the remnant stomach after distal gastrectomy, however those after proximal gastrectomy are rare. In this report, we describe an early gastric cancer which developed in the remnant stomach after proximal gastrectomy and was treated by ESD successfully. The patient was a 74-year-old man, who had received proximal gastrectomy 12 years before. A depressed lesion was found at the lesser curvature of the lower gastric body of the remnant stomach. This lesion was endoscopically supposed to be a mucosal cancer and the biopsy revealed a moderately differentiated adenocarcinoma. Curative en bloc resection of the lesion was achieved by ESD, though there was severe fibrosis along the suture line.
