The interventional radiologist has a diverse and expanding role to play in the management and treatment of patients with disorders of the gastrointestinal (GI) system. These patients generally fall into one of two broad categories. The first category includes patients who are unable to tolerate or achieve adequate nutrition by mouth. In these patients, the interventional radiologist may be consulted to obtain percutaneous enteral access so that nutrition or hydration may be administered. The second category includes patients with benign or malignant strictures or obstruction of a hollow viscus, be it the esophagus, stomach, or small or large bowel. In these patients, the goal is to treat the obstruction when possible, or else decompress proximal to the obstruction for palliation of symptoms.
