Laparoscopic Sleeve Gastrectomy

Weill Cornell weight loss surgeons have pioneered sleeve gastrectomy (also known as vertical gastrectomy or gastric sleeve) as a procedure for weight loss which involves removing about 60% of the stomach, and re-shaping it into a long tube, or "sleeve". This procedure preserves the pyloric valve, which regulates the passage of the stomach contents into the small intestine. By preserving the pylorus, the sleeve gastrectomy allows the normal process of stomach emptying to continue. We offer this surgery as a laparoscopic or occasionally as a robotic procedure. Long-term results are available and the data suggest the weight loss may be similar to that of gastric bypass for many patients.

This type of laparoscopic bariatric surgery is now done mostly as a stand-alone procedure but may also be part of a staged operation for certain patients. As a patient loses weight (over a 6-18 month period), their risk for complications after subsequent surgery decreases dramatically. At the appropriate time, they can be safely offered a second-stage operation, either gastric bypass or duodenal switch.
