The OAGB is also known as the ‘single loop bypass’ and the mini-bypass. It is a minimally invasive procedure performed with a laparoscopic technique.
There are basically two main steps to this operation:
- The surgeon creates a small tube-like stomach pouch which is detached from the rest of the stomach.
- This gastric pouch is then connected up to the intestine, bypassing up to 200cm of the total length of the small bowel.
