Sleeve Gastrectomy The surgery
The sleeve gastrectomy procedure is performed with laparoscopic (keyhole) technique under general anaesthesia. Five small incisions (between 5 and 15mm in length) are made for the insertion of keyhole surgery instruments. Using these instruments, the size of the stomach is reduced by stapling along the length of the stomach (over a sizing device called a bougie) to form a long tube that looks similar to a banana. The majority of the stomach is then removed and discarded.
