This process is a malabsorptive and restrictive surgery.

Roux en Y Gastric Bypass

This process is one of the most commonly performed bariatric surgery procedure in the world. The stomach cuts from the bottom of the esophagus. With this way, the stomach is divided into two pieces with 30 cc and 50 cc volumes. So we get a small stomach pouch that the foods will go into and a larger stomach pouch that will not use. Then the surgeon cuts the small intestine from 40-60 cm and connects the lower end of the small intestine to the small stomach pouch. The high-end of the small intestine from the big blind stomach pouch where the bile and pancreatic secretions connects to the middle of the small intestine that connects to the new small stomach.

Mini Gastric Bypass

This process has been described as a modification of the Roux-en-y gastric bypass in 1997. This process is simpler and shorter operation. First, the surgeon creates an elongated stomach pouch. This pouch is larger than roux en Y gastric bypass. Then the small intestine is connected to the small stomach.


A blind gastric pouch that can not be check endoscopically is left in the body.
