Vertical Sleeve Gastrectomy

Focusing on both food restriction and appetite suppression, our surgeons offer a popular and highly-effective weight loss surgery option – The Vertical Sleeve Gastrectomy. During this minimally invasive laparoscopic procedure, also called Laparoscopic Sleeve Gastrectomy (LSG), the stomach is vertically divided with a line of staples removing a large portion of the stomach. The remaining stomach is a long tube, shaped like a very slender banana, approximately 80 – 160 cc’s.The surgery helps you lose weight by restricting the amount of food (and, therefore, calories) that can be eaten at one time. The part of the stomach that is removed secretes a hormone called ghrelin which is responsible for appetite and hunger. Because of the decreased amount of ghrelin, sleeve gastrectomy patients experience a loss or reduction in appetite. This loss of appetite also helps them achieve weight loss.The remaining tube-shaped stomach has a limited ability to stretch and therefore, resists the amount of food you are able eat. This resistance to stretching creates feelings of fullness when you eat very small amounts of food and that feeling often lasts for an extended time.The clinical results of weight loss and co-morbidity resolution associated with the LSG procedure has prompted some surgeons to forego second stage procedures for some patients, as well as offer LSG as a stand alone procedure for patients with lower BMI’s. Our surgeons primarily use the sleeve gastrectomy as a stand-alone procedure.Current clinical evidence reflects short-term outcomes: EWL at 12 months of 45% to 63% with significant comorbidity improvement or resolution. Some studies have shown three-year results of patients with BMI < 55 comparable to LRYGB, the long-term durability of the weight loss or co-morbidity resolution associated with the procedure has not yet been established.

1.Laparoscopic "key-hole” operation requiring only an overnight stay in the hospital
2.The intestines are not re-routed
3.Reduction in "hunger hormone” reduces cravings

2.Although very rare, potential for complications

Vertical Sleeve FAQ’s:
How big will my stomach be after surgery?
The size of your stomach will vary depending on the surgeon. All surgeons use a tube to guide them when stapling the stomach. This tube size can vary from as small as 32 French Bougie (1-2 ounces) to as large as 64 French Bougie (6-8 ounces). This is a very important question to ask when considering this surgery, since those patients with larger pouches may have less weight loss.

Is removing the stomach safe?
This type of stomach removal has been performed with the Duodenal Switch procedure since the mid 1980’s. It does involve stapling, just like in the gastric bypass and has similar risks. Interestingly, patients do not ever return asking for their stomach back but many do wonder if it is possible to reduce the size of it again.

Will I need to take vitamins?
Vitamin deficiencies are rare with this procedure because there is no intestinal bypass. However, the procedure is very restrictive so most surgeons recommend that patients take a multivitamin, calcium and possibly a B12 vitamin after surgery.

Will I regain weight?
All patients undergoing weight loss surgery are at risk for weight regain. None of the operations can prevent this. Those patients who maintain good dietary habits and exercise patterns are more likely to keep the weight off than those who do not exercise and who snack frequently.

What will my diet be like after surgery?
The diet will progress over the first year. It usually starts with 2-4 weeks of liquid protein drinks and water. Patients gradually progress to thicker food items and by two months are able to eat seafood, eggs, cheese and other regular foods. The diet generally recommended is low calorie (500 per day), high protein (70gm per day), low fat (30 gm per day) and low carbohydrates (40 gm per day).The calorie intake increases over the first year and by 12 months many patients have achieved their goal weight and consume between 900 and 1500 calories per day. This final calorie intake depends on level of activity, age and gender(men can usually consume more calories and maintain their weight).
