The laparoscopic gastric bypass involves two steps. First, the stomach is divided into two parts. A small stomach pouch is created that receives food from the esophagus. It typically holds about 30 mls and becomes the patient's new stomach. The larger remaining stomach is left behind and drains normally into the small bowel. Secondly, the small bowel is divided downstream. The cut end of the small bowel is then brought up and attached to the new stomach so that it may empty. This is the so-called Roux Limb. The small bowel is also reconnected downstream to allow for drainage of the unused stomach and proximal small bowel.
How does the Gastric Bypass compare to the other surgeries?
- This is a more complex surgery than the Sleeve Gastrectomy.
- Low mortality risk.
- Low peri-operative risks.
- Minimal short-term complication rates.
- Short-term risk of leakage.
- Long-term risk of ulcer, stricture, and nutritional issues.
- Weight loss comparable with the Vertical Sleeve Gastrectomy.
