Abstract
An 89-year-old woman was admitted to our hospital complaining of vomiting after eating. Endoscopic examination showed a bulky polypoid lesion with a stalk on the antral greater curvature of the stomach, prolapsing into the duodenal bulb. The pathological findings of the biopsy specimen showed well-differentiated tubular adenocarcinoma. Using the intrabulbar retroflexion method, the tumor was pushed back into the stomach. Since a good view of the stalk of the tumor could not be obtained, endoscopic submucosal dissection (ESD) was not performed. Therefore, distal gastrectomy was performed. The tumor was 0-I type, 90 mm×65 mm in size, on the antral greater curvature of the stomach.
Histological examination showed tub1, pT1a (M), ly0, v0, pPM0, pDM0, n0. The patient recovered gradually, and she was discharged 26 days after the operation. A rare case of ball valve syndrome with 0-I type gastric cancer was described.
