What is GJ surgery?

Published in Gastrointestinal Surgery 1 min read

GJ surgery, or gastrojejunostomy, is a surgical procedure that creates a connection (anastomosis) between the stomach and the jejunum[1]. The jejunum is the middle section of the small intestine.

Understanding Gastrojejunostomy

This surgery alters the normal digestive pathway. Here's a breakdown:

  • Normal Digestion: Food travels from the stomach to the duodenum (the first part of the small intestine) and then to the rest of the small intestine.
  • Gastrojejunostomy: Food bypasses the duodenum and enters the jejunum directly from the stomach.

How is a Gastrojejunostomy Performed?

The surgery can be performed in several ways[1]:

  • Open Surgery: A traditional incision is made in the abdomen.
  • Laparoscopic Surgery: Small incisions are made, and a camera and specialized instruments are used.
  • Endoscopic Surgery: The procedure is performed using an endoscope (a flexible tube with a camera) inserted through the mouth.
  • Technique: The connection between the stomach and jejunum can be created by hand-sewing the tissues together or by using surgical staples[1].
