Gastrostomy allows enteral nutrition to continue in patients who are unable to meet their caloric requirements orally. Though the indications for gastrostomy placement are varied, dysphagia secondary to a neurological condition is the most common. These catheters were initially placed surgically, but percutaneous endoscopic placement is now the routine in most centers. Interventional radiologists have been performing this procedure under fluoroscopic guidance for several years with encouraging results. Percutaneous radiological gastrostomy is reported to have a success rate comparable to that of the endoscopic method, with lower morbidity and mortality rates. A further benefit is that it may be performed in patients for whom the endoscopic method would be difficult or dangerous, such as those with head and neck malignancies. One of the main factors currently limiting the use of this procedure is the shortage of interventional radiology facilities and specialists.This article describes a technique for routine percutaneous radiological gastrostomy catheter placement and procedural variations for difficult cases. Indications and contraindications will be discussed, as will complication rates and how these compare with the traditional methods of gastrotomy tube placement.
KEYWORDS: Gastrostomy, gastrojejunostomy, interventional radiologyObjectives: Upon completion of this article, the reader will (1) understand how gastrostomy provides a mechanical means for the continuation of enteral nutrition in patients who are unable to meet their caloric requirements and (2) be able to describe a technique for routine percutaneous radiological gastrostomy catheter placement, procedural variations, indications and contraindications, as well as success and complication rates and how these compare with nonradiological methods of gastrostomy tube placement.

It can also be used for palliative decompression of proximal small bowel or gastric outlet obstruction. The ideal procedure should provide an effective and aesthetically acceptable gastrostomy, at low cost, with minimal risk of both short-and long-term complications.
