Mini Bypass Surgery

LAPAROSCOPIC OMEGA LOOP BYPASS (MINI Bypass) 

Omega-Loop gastric bypass surgery is a simplified version of the Roux-en-Y gastric bypass surgery.  It is also known as Mini Gastric Bypass Surgery or Single Anastomosis Gastric Bypass Surgery.

It works by restricting the amount of food that can be eaten at one time a small stomach pouch, approximately 50 milliliters in volume and by altering gut hormones that affect appetite control. 

Weight loss results with Omega-Loop gastric bypass have been proven to be both safe and successful. Omega-Loop is sometimes referred to as mini gastric bypass as it involves only making one anastomosis (connection) instead of two like during Roux-en-Y. 

During Omega-Loop, the stomach pouch is reduced in size and interconnected to the small intestine. This causes the food ingested to bypass the duodenum and the first section of the small intestine. 

This bypass results in earlier satiety (feeling of fullness) and fewer calories absorbed, in turn leading to weight loss. 

The larger part of the stomach is detached but remains in the body and continues to produce digestive juices that help with digestion. 

Because Omega-Loop involves making one anastomosis instead of two, it can be performed in less time than Roux-en-Y and involves less risks and a shorter recovery.

Advantages of Mini Bypass Surgery

1. Produces significant long-term weight loss (60 to 80 percent excess weight loss)
2. Restricts the amount of food that can be consumed
3. May lead to conditions that increase energy expenditure
4. Produces favourable changes in gut hormones that reduce appetite and enhance satiety
5. Typical maintenance of >50% excess weight loss

Disadvantages of Mini Bypass Surgery

1. It is technically a more complex operation than Laparoscopic Sleeve Gastrectomy (LSG) and potentially could result in greater complication rates
2. Can have long term GASTRIC reflux and conversion to RY gastric bypass may be required
3. Can lead to long-term vitamin/mineral deficiencies particularly deficits in vitamin B12, iron, calcium, and folate
4. Generally has a longer hospital stay than the Adjustable Gastric Band (AGB)
5. Requires adherence to dietary recommendations, life-long vitamin/mineral supplementation, and follow-up compliance
