A pyogenous gastric abscess that developed following ingestion of a piece of a wooden skewer: successful treatment with endoscopic incision.

A 62-year-old man with a medical history of duodenal ulcer was referred to our department for endoscopy, because of epigastralgia associated with mild anorexia. At endoscopy, a large protruding lesion with the appearance of a submucosal tumor was present at the posterior wall of the gastric body. Trying to perform an aspiration needle biopsy for cytological study, we observed the outflow of pus from the puncture point. An incision, 1 cm in length, was performed via a needle-knife sphincterotomy, which led to drainage of the abscess and disappearance of symptoms. A 2.5 cm long piece of a wooden skewer was found to be embedded into the area of the bulge and was retrieved.
