Mini Gastric Bypass

Mini - Gastric Bypass Surgery in Qatar also every so often called Omega Loop Gastric Bypass or One Anastomosis Gastric Bypass procedure creates a long, narrow tube of the stomach, and is a somewhat technically easier and hence a lower-risk option than the traditional gastric bypass.

At Al Emadi Hospital, a Mini-Gastric Bypass procedure involves the stomach being divided with a laparoscopic stapler so that most of the stomach is no longer attached to the oesophagus and will no longer receive food. The new stomach will be shaped like a small, long tube along the right border of the stomach

Mini-gastric bypass surgery is one of the methods we present for making it happen in an easy and professional manner. The mini-gastric bypass is a simple, safe and effective alternative to other bariatric surgeries resulting in good short and long-term weight loss.

Average weight loss is 68% of excess body weight in the first year and sustained weight loss up to 77% of excess body weight 2 years after the surgery. It can be easily reversed or revised should the need ever arise.


  • It’s less invasive – With mini-gastric bypass there are typically fewer incisions because there is less internal manipulation required. Fewer incisions mean less chance of infection.
  • It’s faster than RNY – A typical RNY procedure can take up to 2 hours whereas a mini gastric bypass is usually completed with an hour.
  • There is less rerouting of the small intestine – In RNY surgery the small intestine is completely severed before being reattached to the new stomach pouch. With mini-gastric surgery the new pouch is simply joined to the side of the intestine.
  • Shorter recovery times – Because there are fewer incisions and less manipulation of the small intestine recovery time is typically shorter than that for standard RNY surgery.


  • Chance of dumping syndrome – This phenomenon occurs when foods move too quickly through the stomach into the intestines. Diarrhoea, dizziness and nausea typically occur.
  • Chance or reflux gastritis – This condition occurs when bile backs up into the stomach and oesophagus.
  • Potential for infection – While the risk of infection is usually lower than with RNY surgery it does exist, and patients need to be aware of that.
