Vertical Sleeve Gastroectomy

Vertical Sleeve Gastroectomy, what is commonly known as VSG Surgery, is becoming one of the newest popular bariatric weight loss surgeries. It is less restrictive than some of the other bariatric weight loss surgeries, has no effect or change to the small intestine, and the recovery time is shorter. To understand the difference between the vertical sleeve gastroectomy and the other bariatric weight loss surgeries, the following is a brief overview of other bariatric weight loss surgery procedures.

There are currently four main surgeries performed in the United States for bariatric weight loss at this time.  The first and probably most well known is the Rouy-en-Y Gastric Bypass Surgey.  This is both a restrictive and malabsorptive procedure. It is also one of the most dangerous surgeries in use at this time. Patients usually loose up to 85 % of their ideal body weight with Rouy-en Gastric Bypass Surgery.  The stomach is made smaller and the small intestine is re-routed to which causes malabsorption and results in rapid weight loss.  The portion of the stomach that is separated from the smaller pouch is left in the body and attached to the small intestine in the “by pass” portion of the surgery.  The Duodenal Switch surgery (also called biliopancreatic diversion) is similar to the Gastric bypass surgery in that it changes the size of the stomach and causes malabsorption.In the Duodenal Switch, the stomach is reduced to the size and shape of a banana and the remaining stomach material is removed.  Then the small intestine is then re-routed to cause malabsorption.  When surgeons began performing the Duodenal switch surgery for severely obese patients, they would sometimes break the surgery into two parts.  The first part of the process was to perform the Vertical Sleeve Gastroectomy and use this as a tool for the patient to lose a portion of his excess bariatric weight so that the second portion re-routing of the small intestine could be performed later on a smaller sized patient for safety.  Many surgeons found that patients were losing significant amounts of bariatric weight, approximately 55% of their ideal body weight, before the second part of the surgery was performed which is known as the Duodenal Switch. This observation brought about the fourth type of surgery which is known ast he Vertical Sleeve Gastroectomy. 

The Vertical Sleeve Gastroectomy is performed by sectioning one portion of the stomach with staples to the size of a banana and the remaining outer portion of the stomach is removed.  This restrictive procedure causes bariatric weight loss by limiting the amount of food the patient can eat. Most of the Vertical Sleeve Gastroectomy surgeries are performed laproscopically and the recovery time is much shorter than with the other types of bypass type surgeries. Over all this is one of the least dangerous weight loss surgeries as it does not cause malabsorption like the other weight loss surgeries besides the lapband surgery.
