Radiologic gastrostomy.

Abstract

Radiologic gastrostomy has a higher success rate and a lower complication rate and offers a greater choice of tubes than percutaneous endoscopic gastrostomy (PEG). The position and configuration of the stomach and colon are clearly seen under fluoroscopy, and ultrasound can be used to locate the liver. Radiologic gastrostomy procedures can be performed when there are oropharyngeal tumors, or esophageal strictures and stents, and can be performed under local anesthesia alone. Peroral push-gastrostomies are preferable for palliative care and for patients with neurogenic dysphagia, but percutaneously inserted tubes should be used in patients with upper gastrointestinal cancers in order to avoid tumor seeding. Unfortunately, awareness of and access to radiologic techniques are still limited and this has led to the development of "adventurous" techniques for placing endoscopes in stomachs rather than applying simple fluoroscopic alternatives.
