Abstract
The patient was a man in his 50's. In July 2014, during wood splitting, a part of a metal wedge that a colleague was using 4m away broke off and hit the patient's abdomen on the left side. The puncture wound in the skin was about 5mm in diameter. There were no metal pieces at the scene. The patient was hospitalized with the chief complaint of wound pain. Examination revealed no evidence of peritonitis. An abdominal X-ray and CT revealed a foreign body in the duodenum, with a little intraperitoneal gas. We diagnosed gastric perforation by a foreign body, and performed emergency surgery. At surgery, we found gastric perforation, but no other organ damage. We removed the foreign body by fenestrating the small intestine. We report a case of abdominal penetrating trauma and gastric perforation encountered by us, along with a discussion of the literature.
