Laparoscopic sleeve gastrectomy (LSG) sometimes referred to as vertical sleeve gastrectomy (VSG) is a type of bariatric (weight loss) surgery. This procedure is also often called gastric sleeve surgery. During the procedure, the surgeon permanently removes between 80-85% of the patient’s stomach. The patient’s stomach is reduced to a small pouch that resembles the shape of a banana.

Part of the stomach that is normally removed during VSG surgery is called the “fundus” and is the portion that curves outward. The fundus is responsible for secreting the hormone ghrelin which is what makes us feel hungry.

How Does A Vertical Sleeve Gastrectomy Work?

LSG or laparoscopic sleeve gastrectomy helps obese individuals lose weight through:

  • The reduction of the size of their stomach – patients can not eat as much food in one sitting and they feel “full” much faster after laparoscopic sleeve gastrectomy. The smaller stomach also empties more slowly so this “full” feeling lasts longer.
  • The removal of the fundus decreases the amount of ghrelin – the hormone that tells us we are hungry and prompts us to eat. The reduction of ghrelin reduces the appetite and makes it easier for the individual to lose weight.

Who Is A Candidate For Gastric Sleeve Surgery (VSG)?

The qualifications for bariatric surgery including VSG include:

The patient’s body mass index (BMI) is 40+

The patient’s body mass index (BMI) is 35 or above and they suffer from an obesity-related illness like type 2 diabetes or high blood pressure

The patient has been unable to lose weight through non-surgical means such as diet and exercise.

The patient is in good overall health and they do not have any medical or mental conditions that would exclude them from undergoing surgery.

How Is A Sleeve Gastrectomy Performed?

LSG surgery is performed under general anesthesia and lasts between 60 and 90 minutes.

  • 1. During laparoscopic sleeve gastrectomy, the surgeon makes between 2 and 5 small incisions in the abdomen.
  • 2. A laparoscope, a surgical instrument that is outfitted with a tiny camera, is inserted through one of the incisions. This will help guide the surgeon during the procedure by providing “real-time” video on a nearby monitor.
  • 3. A special gas is pumped into the patient’s abdomen to open up the space and allow the surgeon access to perform the surgery.
  • 4. Other small surgical instruments needed to perform the procedure are placed through the other incisions.
  • 5. The surgeon excises and removes a large portion of the stomach pouch and fastens the remaining edges together with surgical staples. There are no alterations done to restrict food from entering or exiting the stomach.
  • 6. The surgical tools are removed from the incisions and they are sutured closed.

When Will I Start Seeing Results From LSG Surgery?

If the correct diet and exercise plan is followed after the LSG procedure, you can expect to lose a significant amount of weight in the first three months. This may be as much as 30% of your excess weight After 6 months, you can expect to have lost between 45-50% of your excess weight*. After the 6-month mark, weight loss tends to taper off and after a year, the average weight loss from a laparoscopic gastric sleeve is 60% to 70% of excess weight (EWL).

*Excess weight is the difference between current weight and ideal weight.

Our patient is 5’8” tall and their ideal weight or goal weight would be about 145 pounds.
