During this procedure the surgeon removes about 85 percent of the stomach so that it takes the shape of a tube or sleeve. This operation is performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large incision. He or she inserts a viewing tube with a small camera (laparoscope) and other tiny instruments into these small incisions to remove part of the stomach. The tube-shaped stomach that is left is sealed closed with staples.

The following is from my surgeon's page:
How a sleeve gastrectomy works to help you lose weight
During this procedure, a thin vertical sleeve of stomach is created using a stapling device and the rest of the stomach is removed. The sleeve is about the size of a banana. This procedure limits the amount of food you can eat and helps you feel full sooner. It allows for normal digestion and absorption. Food consumed passes through the digestive tract in the usual order, allowing it to be fully absorbed in the body.
The sleeve gastrectomy procedure
The majority of weight loss sleeve gastrectomies performed today use a laparoscopic technique, which is considered minimally invasive. Laparoscopic surgery usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open surgical procedures.
The length of time of the surgery varies. One study found that the average operative time was 1 to 2 hours and the average hospital stay was 1 day. Patients usually return to normal activities in 2 weeks and are fully recovered in 3 weeks.
