Mini Gastric Bypass MGBP

In this procedure, the surgeon divides the patient’s stomach into two parts.

The smaller part, which connects to the esophagus, is reshaped into a long narrow tube and will serve as the new mini stomach; it will only hold 4 to 7oz of food. The larger part of the stomach will remain alive and inside your body. It will still produce digestive juices to aid in digestion but it will no longer come into contact with food.

The surgeon measures the length of your small intestine that will be bypassed (a surgically created pathway dodging the normal anatomical pathway) This bypass section will include all of the duodenum (initial part of the intestine) and part of the jejunum (middle section of the intestine) and it’s usually between 5 to 7 feet from where the small intestine connects to the larger portion of your old stomach. The length of the bypass is determined by your specific physical condition and lifestyle situations.

Your surgeon will then connect the end of your new mini stomach pouch to the bypass point of the small intestine; this connection point is called an ANASTOMOSIS. Once this is completed your surgeon will reinforce the outer circumference of the anastomosis with sutures and close the abdominal incisions with sutures.


The main features from this procedure are:

  • Has only 1 Anastomosis instead of 2 as with the gastric bypass
  • Stomach pouch is created on the lesser curvature of the stomach
  • Reversible “can be undone”
  • Laparoscopic
  • Simpler procedure
  • Less operative time
  • Faster recovery than the gastric bypass
  • Lower risk of leakage or intestinal obstruction as compared to gastric bypass
  • Very Effective alternative for sweet-eaters
  • 2 night stay at hospital
  • Surgical time: 1 to 3 hours
