[Laparoscopic Gastrectomy for Gastric Adenocarcinoma of the Fundic Gland Type - Report of a Case].

A 69-year-old man underwent esophagogastroduodenoscopy, which showed a slightly depressed lesion at the greater curvature of the gastric body. We diagnosed gastric adenocarcinoma of the fundic gland type(GA-FG)from examination of the biopsy specimen. Endoscopic submucosal dissection(ESD)was performed for curative resection. The pathological examination revealed a positive vertical margin. Consequently, laparoscopic gastrectomy was additionally performed. GA-FG has recently been proposed as a new entity of gastric adenocarcinoma. GA-FG mostly develops without Helicobacter pylori infection and often invades the submucosa, regardless of size. However, GA-FG rarely demonstrates lymphatic and venous invasion despite deep submucosal invasion. Since most GA-FG cases undergo ESD, few reports of surgical resection exist. Here, we report our experience of laparoscopic gastrectomy for GA-FG.
