gastrojejunostomy

Definition of gastrojejunostomy

gastrojejunostomy (GAS-troh-JEH-joo-NOS-toh-mee): A surgical procedure that connects part of the stomach to the jejunum (the middle part of the small intestine). This allows food and other stomach contents to pass directly from the stomach to the jejunum without passing through the first part of the small intestine called the duodenum. Gastrojejunostomy may be done during surgery to remove part of the stomach that has cancer blocking the opening into the small intestine. It may also be done as part of weight-loss surgery.
