Abstract
A 83-year-old man who underwent endoscopic hemostasis for bleeding from a gastric submucosal tumor one year earlier was admitted to the hospital for abdominal pain after meal. Abdominal CT scan showed a gastric tumor prolapsing into the duodenum and gastrectasis. Emergency surgery was performed with a suspicion of a gastric submucosal tumor presented with ball valve syndrome (BVS). Operative findings showed the tumor to be prolapsing and impacting into the duodenum and the gallbladder to have necrotized partially, from where bile leaked. We reduced the tumor into the stomach and performed a partial gastrectomy and a cholecystectomy. The tumor was a gastric submucosal tumor 4 cm in diameter and histological findings showed a low risk gastrointestinal stromal tumor (GIST) which revealed c-kit(+) and CD34(+). The gallbladder necrotized partially, but there were not perforation and gallstones. This case of GIST of the stomach presented with BVS with biliary peritonitis, which is rare, is reported with a review of the literature.
