Laparoscopic Sleeve Gastrectomy

What is a Laparoscopic Sleeve Gastrectomy?

During this procedure, a large portion of the stomach is removed. Unlike gastric bypass, there is no bypass of the small intestines, so the likelihood of a nutritional deficiency is decreased. This procedure is non-reversible.

Frequently Asked Questions

How is a laparoscopic sleeve gastrectomy performed?

A laparoscopic sleeve gastrectomy can be performed using a laparoscope, or a small instrument with a live feed camera attached. Using this, Dr. Balsama can observe the procedure on a screen and perform it using small instruments and incisions, rather than an open incision which can come with some additional risks of complication. The procedure entails reducing the size of the stomach itself by sectioning off and removing about 80% of the stomach. The remaining area of the stomach is about the size of a banana and can still function as normal, only in a smaller capacity. Since this procedure doesn’t bypass the small intestines, there’s no affect on your ability to absorb nutrients.

Where are the incisions made during laparoscopic sleeve gastrectomy?

During laparoscopic sleeve gastrectomy, Dr. Balsama will make several small incisions in the abdomen, allowing access to the stomach. Long instruments will then be placed through the incisions, using a laparoscope that acts as a video camera to guide and remove a section of the stomach. Only the stomach is affected, and the intestines are not removed or bypassed.

How does the laparoscopic sleeve gastrectomy work?

Laparoscopic sleeve gastrectomy works by restricting the size of the stomach so that less food can fit. Patients will feel fuller sooner and for a longer period of time, resulting in dramatic weight loss. By reducing the size of the stomach, fewer “hunger hormones” are produced, contributing to weight loss. The intestines are completely left intact, so the procedure should not cause a decrease in the absorption of nutrients.

Is a laparoscopic sleeve gastrectomy reversible?

A laparoscopic sleeve gastrectomy procedure is irreversible, meaning results are permanent. Once a large portion of the stomach is removed, it cannot be replaced. The decision to undergo laparoscopic sleeve gastrectomy can lead to life-changing health benefits, making the procedure worth it for many patients. Dr. Balsama will meet with you to ensure that the procedure is right for you.
