One Anastomosis Gastric Bypass
"Gastric bypass is a weight loss surgery which involves reducing the size of the stomach to promote early satiety and bypassing a section of the intestine to limit food absorption. This is usually carried out by the Roux-En-Y procedure in which the stomach and intestine are reconnected by creating two new communications or anastomoses. A One anastomosis gastric bypass is a modification of this procedure that simplifies the technique, reduces operating time and minimizes complications."
