Percutaneous Radiologic Gastrostomy Tube Placement Techniques

Area of Science:

• Interventional Radiology
• Gastroenterology

Background:

• Gastrostomy tubes are frequently placed by interventional radiologists.
• Multiple radiological techniques exist for gastric access.

Purpose of the Study:

• To review and compare common radiological gastrostomy tube techniques.
• To guide the selection of the most appropriate technique based on patient factors and institutional resources.

Main Methods:

• Review of antegrade, retrograde, and balloon-assisted gastrostomy tube placement techniques.
• Comparison of technique-specific indications, preprocedural workup, procedural steps, and postprocedural care.

Main Results:

• Antegrade technique offers comparable outcomes to percutaneous endoscopic gastrostomy but requires oral/esophageal access.
• Retrograde technique reduces infection risk, shortens procedure time, and lowers radiation exposure.
• Balloon-assisted technique demonstrates the shortest procedure times with comparable outcomes.

Conclusions:

• Understanding and comparing these techniques is crucial for patient-centered care.
• The choice of technique should be individualized based on clinical presentation and available resources.
