A case of gastric carcinoid tumor associated with type a atrophic gastritis treated with endoscopic aspiration submucosectomy

The patient was a 43-year-old man. He was pointed out to have a gastric submucosal tumor in 1993. The tumor proved to be a carcinoid by bioptic histology in 1999. He was referred to our hospital for treatment. The gastric carcinoid, located in the middle body, 9 mm in diameter, oval in shape and confined to the submucosal layer as seen by endosonography, was associated with type A chronic atrophic gastritis. Endoscopic aspiration submucosectomy was performed on him using mucosector (Top Co., Japan). The tumor was successfully resected. Nine months later, follow-up endoscopy revealed no finding of residual or recurrent tumor. This technique was considered useful for the resection of the submucosal tumor approximately 1 cm in diameter confined to the submucosal layer.
