Gastrojejunostomy Catheter Placement and Management

Gastrojejunostomy catheters are a common means of long-term enteral access in patients unable to meet their nutritional requirements through oral intake. The choice of gastrojejunostomy versus gastrostomy tubes in these patients depends largely on aspiration risk, which is a relative contraindication of gastrostomy placement. Initially a surgical procedure, gastrojejunostomy placement is now frequently performed endoscopically or with radiologic guidance. Additionally, in patients with prior gastrostomy placement who need more distal enteral access, gastrostomy to gastrojejunostomy conversion can easily be performed by an endoscopist or interventional radiologist. This article reviews common techniques for percutaneous radiologic gastrojejunostomy placement, conversion, and exchange, as well as indications and contraindications. Complications will be discussed and compared across the different methods for gastrojejunostomy placement.
