Gastric Sleeve

The Gastric Sleeve (also known as the sleeve gastrectomy or vertical sleeve gastrectomy) procedure that reduces weight primarily through restriction, or creating a smaller stomach. It is believed that gastric sleeve significantly reduce the production of the “hunger hormone” ghrelin, which reduces the amount of hunger patients feel after the surgery. Dr. Sashi Ganta is one of the most experienced gastric sleeve surgeons in Austin and was among the first surgeons to perform gastric sleeve surgery in Austin. He had been performing the Sleeve procedures since 2006 in his Austin Bariatric Surgery practice.


The gastric sleeve is performed as a minimally invasive laparoscopic procedure. This approach leads to reduced pain and scarring and faster recovery. The laparoscopic Gastric Sleeve involves removing about 80% of the stomach, which creates a “sleeve” of your stomach –making it the size and shape of a small banana. The new stomach can hold about 3-4 ounces, resulting in significant restriction which leads to weight loss. The remainder of the stomach is removed, thereby removing most of the hunger hormone producing part of the stomach.


Single incision or SILS approach

Dr. Sashi Ganta is one of the few surgeons in the country to offer the TRUE SINGLE INCISION WITH NO VISIBLE SCAR approach for Gastric Sleeve to suitable patients. Dr. Sashi Ganta pioneered the SILS approach for lap band and is believed to be the first surgeon in Texas to perform the Lapband using trans-umbilical SILS approach in September of 2008. Surgeons from across the country visited Austin to train in the SILS approach from Dr. Ganta and patients travel to Austin from many other states to have the procedure performed by Dr. Ganta. This remarkable technique involves complete performance of the gastric sleeve procedure via one small incision at the belly button leaving no visible scars on the abdomen. This new technique of Trans-umbilical Gastric Sleeve allows patients to have an opportunity for significantly improved cosmetic results and possibly less pain with a faster recovery.


All patients are not candidates for this approach. Results can vary and are not guaranteed even for patients determined to be candidates before the surgery.
