OVERVIEW
This page serves as a guide to gastro-jejunal tubes (G-J tubes) that are used within the field of interventional radiology. Fundamentally, a G-J tube is a literal tube that connects the outside environment to the inside of the patient’s stomach and bowel. It is inserted percutaneously, transversing the wall of the stomach, as well as the abdomen, and the the distal tip of the tube will terminate in the jejunum. Often times it is used to provide nutrition to the patient (by injecting it directly into the jejunum), while gastric contents can be aspirated from the stomach. Look on this page to see how this piece of medical equipment will appear on various imaging modalities.
