This is the modified version of the classic Gastric Bypass which involves splitting the stomach vertically and closing with staplers to shape the stomach like a sleeve, leaving rest of the stomach intact and connecting the 2 meters forward of small intestine to the new stomach in a single connection way. In this surgery, the food ingested moves from the new stomach to the small intestine, bypassing most of it and this slows the absorption of food along with the amount of food that can be eaten because of the size of the new stomach. 
The surgery is usually done like Laparoscopic surgery with the help of little incisions opened around the abdomen and the patient heals within a couple of days.

This surgery combines the qualities of Gastric Bypass and Stomach Sleeve Surgery and the need for vitamin intake is lesser than classic Gastric Bypass surgery.
