Patients with a long-term PEG may suffer from complications and received physical and endoscopic examinations. However, these examinations do not provide information between skin and stomach. We present the findings of computed tomography (CT) for patients with long-term percutaneous endoscopic gastrostomy (PEG). After 1 year PEG (183 patients), 57 patients had received CT examinations. Skin indentation, soft-tissue thickening, peritoneal gap, internal bumper migration, and clinical abnormalities detected by CT examination were recorded. Thickness of subcutaneous fat, muscle, and abdominal wall along the tract were measured. The same parameters at 3 cm away from the tract were obtained for comparison. CT demonstrated that 28 (49.1%) patients present soft-tissue thickening, 19 (33.3%) patients present skin indentation, and 24 (42.1%) patients present a peritoneal gap. One patient with internal bumper migration, 3 patients had buried bumper syndrome, 2 patients had gastric herniation, and 1 patient had esophageal cancer metastasizes to the PEG site. Thickness of subcutaneous fat, muscle, and abdominal wall decreased significant. CT can provide detailed anatomy and orientation along the PEG tube. Familiarity of the CT appearance can minimize potential complications before PEG tube replacement.
