Mini Gastric Bypass
In this method, similar to sleeve gastrectomy, the stomach shaped as a tube with a diameter of 2cm and a volume of 50-60cc (volume of 4 tablespoons of water) continuously with the esophagus and the rest of the stomach is separated. The new and narrow stomach tube is connected with stitches to the intestine (approximately 200cm distant to the ligament of Treitz) without cutting through. The undamaged intestinal integrity and intervention on one site are the most important differences from the Roux-en-Y Gastric Bypass (RYGB).
Mini gastric bypass, which combines some features of standard gastric bypass and sleeve gastrectomy, is an effective surgical intervention. The upper part of the stomach is formed in a tube and ligated to the intestines.
Mini gastric bypass can be preferred as a weight-loss method. Besides, it can be also implemented in patients, who could not lose weight after a gastric band or sleeve gastrectomy, or had experienced complications due to the gastric band and referred to revision surgery.
During this surgery, the upper part of the stomach is separated from the rest of the stomach in the form of a thin tube. Thus a new and smaller stomach is created. This new stomach is connected to the intestine 150-200cm distant to the proximal part. The rest of the stomach and the proximal part of the intestine are left in the abdomen but they do not participate in the digestion process.
How does Mini Bypass Surgery Help to Lose Weight?
1. The feeling of hunger decreases as the signaling between the stomach and brain changes.
2. You feel full with smaller amounts of food.
3. Fewer calories are absorbed as one part of the intestine is out of order.
What are the Long-term Effects of Mini Gastric Bypass?
70-85% of the excess weight is lost within two years after surgery.
Several diseases related to obesity like sleep apnea, type 2 diabetes mellitus, joint disorders, hypertension, and polycystic ovarian syndrome improves or recovers fully thanks to surgery.
