Abstract
Endoscopic submucosal dissection (ESD) has recently been applied to the resection of gastric submucosal tumors other than carcinoid tumors. We describe a case of gastric carcinoid tumor enucleated with ESD. An 82‐year‐old woman was referred for treatment of a gastric tumor. Upper gastrointestinal endoscopy revealed a solitary submucosal tumor in the greater curvature of the gastric body. We diagnosed a carcinoid tumor by histological examination of biopsy specimens. Endoscopic ultrasound revealed a hypoechoic mass in the submucosal layer. Neither lymph node nor liver metastasis was recognized. The serum gastrin level was normal, and this tumor was classified as a type III (sporadic) carcinoid tumor. Endoscopic resection was decided on considering her age, general status, and wishes. We used ESD techniques, because the tumor was too large to be resected by conventional endoscopic mucosal resection. En bloc resection was performed. Histological examination of the 13 × 19 × 11 mm resected specimen showed that the cut end was free of tumor cells. Type III carcinoid tumor is usually treated by surgical resection with lymph node dissection. However, in high‐risk elderly patients we consider ESD to be a therapeutic option for local control of gastric carcinoid tumors.
