This study presents a new percutaneous technique for placing large-bore gastrostomy tubes using fluoroscopic guidance. The method achieved a 97% success rate with minimal complications, offering a safe alternative to traditional procedures.

Area of Science:

  • Medical procedures
  • Gastroenterology
  • Radiology

Background:

  • Percutaneous gastrostomy tube placement is a common procedure.
  • Existing methods may have limitations for large-bore tube insertion.

Purpose of the Study:

  • To develop and evaluate an improved percutaneous technique for inserting large-bore gastrostomy tubes.
  • To establish a safe and effective alternative to endoscopic methods.

Main Methods:

  • A retrograde approach using fluoroscopic guidance to catheterize the esophagus.
  • Passage of a guide wire from the gastrostomy site, up the esophagus, and out the mouth.
  • Advancement of a 20-24 F endoscopic push-type gastrostomy tube over the wire.

Main Results:

Related Experiment Videos

  • Successfully placed 31 out of 32 large-bore gastrostomy tubes (97% success rate).
  • No major procedural or postprocedure complications were reported.
  • Minor complications included lip laceration (3%), exit site infection (3%), and tube dislodgement (6%).

Conclusions:

  • Radiologic placement of large-bore endoscopic gastrostomy tubes is feasible without direct endoscopy.
  • The developed percutaneous technique is rapid, easy to perform, and safe.
