Percutaneous treatment of small bowel obstruction due to a gastrostomy tube.

Inadvertent transmigration of a gastrostomy tube through a gastrostomy stoma occurred in a patient with a chronic neurological disorder. This led to small-bowel obstruction by the 30 ml balloon of the catheter. Percutaneous transabdominal puncture of the balloon was performed under fluoroscopic control using a long 22-gauge needle with immediate relief of the obstruction and subsequent passage of the catheter.
