Abstract
A 79-year-old woman with senile dementia had repeated vomiting after percutaneous endoscopic gastrostomy (PEG). Simple abdominal CT findings showed diffuse emphysema in the gastric wall, portal venous gas and gastric hypomotility. Gastrointestinal endoscopic examination revealed sporadic spotty erythema on the gastric mucosa. After discontinuance of enteral nutrition, the above findings improved after two days. We diagnosed a rare case of gastric emphysema caused by PEG.
