Colocutaneous fistula after percutaneous endoscopic gastrostomy in a remnant stomach.

An 82-year-old woman underwent percutaneous endoscopic gastrostomy (PEG) 5 years after partial gastrectomy for cancer. Four months after PEG insertion, a colocutaneous fistula was noted at exchange of the PEG tube. Colocutaneous fistula is a rare and major complication of PEG with 10 reported cases to date. In eight of the 11 reported cases, including this case, fistulas appeared late (>6 weeks) after PEG insertion. This complication may heal after removal of the PEG alone, if the fistula has formed completely; otherwise a surgical approach is necessary for the treatment. Since five of the 11 reported patients had previously undergone abdominal surgery, prior abdominal surgery may increase the risk of a colonic injury after PEG. Open surgical gastrostomy is a wiser option when performing gastrostomy in patients with prior abdominal surgery.
