Abstract: A safe sleeve gastrectomy and intestinal switch reduces gastric volume and calorie intake as a weight loss treatment. The safe sleeve gastrectomy and intestinal switch utilizes a safety pocket to increase safety and guide division of the stomach. An instrument tunnel is created to facilitate division of the stomach into a pouch and a sectioned portion. In this manner, over or complete mobilization of the stomach is avoided. The sectioned portion may be lifted for increased visibility to facilitate its mobilization and removal from the patient. The small intestine can then be separated from the stomach and divided into shortened segments, one of which is reattached to the stomach.
