Is a minimally invasive procedure that partitions the stomach into a long, narrow tube and a separate larger piece.
The smaller stomach is attached about 6 feet down in the small intestine. The larger stomach is sealed and left unattached. Unlike some other kinds of bariatric surgery, MGB is done laparoscopically, completely through five one-inch incisions in the abdomen. In laparoscopic procedures, the surgeon never opens the abdomen.
