Overview

Sleeve gastrectomy as weight loss surgery is a relatively new procedure that is rapidly gaining popularity due to the many advantages it offers over other weight loss surgery procedures

It is currently indicated as an alternative to the Lap-Band® procedure for low weight individuals and as a safe option for higher weight individuals.

The Sleeve Gastrectomy allows any BMI patient to undergo weight loss surgery laparoscopically. Most patients with a BMI under 60 kg/m2 achieve successful, effective weight loss in a manner similar to the gastric bypass or duodenal switch. Some patients with much higher BMI may need a second stage to the procedure, again performed laparoscopically at a later date. Most patients can lose 75 to 80% of their excess body weight over 6-12 months with sleeve gastrectomy alone.

W eight loss surgery patients must be aware of pre and post surgery requirements.

The sleeve gastrectomy offers the following advantages:

• a. It does not require disconnecting or reconnecting the intestines.
• b. It is a technically simpler operation than the gastric bypass or the duodenal switch
• c. It may be a safer operation for patients with a body mass index (BMI) more than 60. To figure out your BMI.
• d. Does not require periodic maintenance such as tightening and refills as in the case of the gastric band.

Disadvantages are:

• a. Some higher BMI patients may need to have a second stage procedure later to help lose the rest of the weight.
• b. Because the stomach is removed, it is not reversible.

Posible Complications

Like any surgical operation, sleeve gastrectomy has possible complications, such as leakage, dilation of the sleeve (which allows for more food intake) and other usual complications associated with bariatric surgery, though the risks are known to be much lower than the gastric bypass and duodenal switch.

Procedure

Weight loss treatment is acheived solely through gastric restriction (reduced stomach volume). The stomach is restricted by stapling and dividing it vertically and removing more than 85% of it. This part of the procedure is not reversible. The stomach that remains is shaped like a very slim banana and measures from 1-5 ounces (30-150cc), depending on the surgeon performing the procedure.

Hospitalization

The sleeve gastrectomy procedure usually requires one night in the hospital and five days recovery in a hotel or recovery retreat before the patient can fly home.
