Weight Loss Surgery Types
-
A portion of the outer part of the stomach is surgically removed, leaving behind a banana-shaped pouch.
-
The top part of the stomach is reformed into a small pouch and joined to the middle part of the intestine, ‘bypassing’ the first part of the intestine. This type is called a Roux-En-Y Gastric Bypass [RYGB].
-
The top part of the stomach is reformed into a small tube and joined (once) to the middle part of the intestine, ‘bypassing’ the first part of the intestine.
This type of gastric bypass is called a One-Anastomosis Gastric Bypass, but sometimes referred to as a Mini-Bypass.
-
Converting an existing weight loss surgery to a new one. Most often converting a gastric band to a gastric bypass.
