title: Pneumoperitoneum after percutaneous endoscopic gastrostomy: a case report and review.
abstract: A complication of percutaneous endoscopic gastrostomy (PEG) is perforation of a hollow viscus. This is typically detected by finding of pneumoperitoneum (PP) on radiographs. However, PP can occasionally be a benign finding. A review of the literature shows many causes for a benign PP, and it has been noted to occur frequently after PEG placement. In the absence of signs or symptoms of peritoneal inflammation, PP usually requires no further investigation or treatment.
