Gastrojejunal anastomosis
Surgical connection between the gastric pouch and jejunum in gastric bypass procedures.
Full Definition
The critical surgical junction created during Roux-en-Y gastric bypass where the small gastric pouch is connected to a limb of jejunum, bypassing the majority of the stomach and duodenum. This anastomosis can be created using stapling devices, hand-sewn techniques, or a combination of both. The size and configuration of this connection significantly impacts weight loss outcomes, with smaller anastomoses promoting greater restriction and weight loss.
Usage
Usage note: Often abbreviated as GJ anastomosis in surgical notes.
