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].
