Radiologic peroral gastrostomy

Abstract

Purpose: To develop an improved percutaneous technique for the insertion of large-bore gastrostomy tubes.

Materials and methods: With use of fluoroscopic guidance, the stomach is punctured and the esophagus is catheterized in a retrograde fashion. A guide wire is passed from the gastrostomy site, up the esophagus, and out of the patient's mouth. A large-bore (20-24 F) endoscopic push-type gastrostomy tube is advanced over the wire, through the mouth, down the esophagus, and out of the gastrostomy site.

Results: Thirty-one successful tube placements were performed in 32 attempts (97% success rate). There were no major procedural or postprocedure complications. Minor complications included one lip laceration (one of 31 = 3%), one minor exit site infection (one of 31 = 3%), and two inadvertent tube dislodgements (two of 31 = 6%).

Conclusions: Radiologic placement of large-bore endoscopic gastrostomy tubes is possible without endoscopy. The procedure is rapid, easy to perform, and safe.
