Gastrostomy tube replacement by endoscopic cannulation of a narrowed previous tube site.

Abstract

Percutaneous endoscopic gastrostomy is warranted when oral feeding is not feasible. Indications include central nervous system disorders, head trauma and occasionally malignancies of upper gastrointestinal tract. If tube replacement after accidental dislodgement is delayed, the track may become narrowed. This may compromise routine replacement and may require repeated procedures. Occasionally no further external dilation is possible. We describe the endoscopic cannulation of the previously used track after its internal cannulation and subsequent external dilation and the successful replacement of a gastrostomy tube.
