The laparoscopic sleeve gastrectomy (SG) or gastric sleeve surgery, involves re-shaping the stomach from a pouch-like shape into a long tube, or “sleeve”. Pre-surgery the stomach looks like a kidney bean and can expand to the volume of several liter-size bottles of soda. With staples, the stomach is converted to look like a banana. This weight loss surgery reduces the capacity and prevents the stomach from expanding significantly.
Before sleeve gastrectomy a regular stomach can hold about six cups of food. The new stomach can hold about a half cup in volume, resulting in a ‘restrictive’ weight loss.
The sleeve gastrectomy preserves the pyloric valve, which regulates the passage of stomach contents into the small intestines. By preserving the pylorus, the sleeve gastrectomy allows the normal process of stomach emptying to continue, while maintaining the feeling of fullness. The remainder of the stomach is removed.
This type of laparoscopic bariatric surgery can be done as a stand-alone procedure or as part of a staged operation. The weight loss is projected to be in the range of 55 to 70 percent of excess body weight. There is no malabsorption created and no foreign body or implant involved. Long-term results are becoming available and the data suggest the weight loss is similar to gastric bypass.
NWH bariatric surgeons have more experience with gastric sleeve surgery than viritually any other bariatric surgeons in the country. Dr. Mitchell Roslin has served as faculty for The Consensus Conference on Sleeve Gastrectomy. He is a teaching proctor for the procedure, teaching many experienced bariatric surgeons the proper technique.
