Gastroenteric fistula complicating percutaneous endoscopic gastrostomy.

BACKGROUND

Gastroenteric fistula occurs in 2% to 3% of patients undergoing percutaneous endoscopic gastrostomy (PEG). The authors identified 12 children with this major complication.

METHODS

A retrospective case note review was performed.

RESULTS

Over a 5-year period, the complication rate for gastroenteric fistula was 3.5% (12 of 343 procedures). Presentation ranged from 1 day to 25 months post-PEG insertion. Eight patients presented with acute intestinal obstruction. The gastroenteric fistulous tract involved the posterior wall of the stomach in all cases. The plain abdominal x-ray was useful in establishing the diagnosis of the gastroenteric fistula.

CONCLUSIONS

Patients with gastroenteric fistula as a complication of PEG insertion can remain asymptomatic for prolonged periods. It often is difficult to make the diagnosis. A plain abdominal x-ray is a useful diagnostic modality.
