Sleeve Gastrectomie

The Vertical Sleeve gastrectomy (VSG) is a restrictive and hormonal procedure.
During the procedure approximately 60-85% of the stomach is removed, creating a “sleeve” or tubular stomach. This procedure can be used on its own, or as a first stage of a two stage procedure. The procedure is done by laparoscopy. Because part of the stomach is removed, this procedure is not reversible.

Procedure

During Sleeve gastrectomy, the right side of the stomach is completely removed. This leaves a sleeve or tubular shaped stomach. The remaining volume is about 60-110 cc.
No reconnection needs to be made with the intestines. No foreign object is implanted in the body.

SILS (Single Incision) Technique

For the sleeve Gastrectomy, the Single Incision technique can be applied.

One incision is made in the umbilical area, which is beneficial for the recovery as well as for the esthetics.

How it Works

The stomach functions as before,  but the quantity of food that can be taken is considerably restricted.
The nerves of the stomach and the outlet valve of the stomach stay intact (pylorus), in contrary to other surgical procedures. Hence dumping syndrome is not a problem.

Patient Selection

This procedure is well tailored for extremely obese patients, as step one in a two-step procedure. Further bariatric surgery will then follow after initial important weight loss. It is also a good option as a primary bariatric procedure in patients with a BMI of 30+, that already have deficiencies in vitamins, anaemia, Crohn and other condition.

Weight Loss

Patients can expect to loose about 60-80% of excess body weight in 12-24 month time.

Advantages

Normal function of the stomach.  A feeling of saturation is achieved by eating a smaller meal. Also as the greater curvature of the stomach is removed, less hormone is produced. This hormone (ghrelin) makes a person feel hungry. It may be used as the first stage operation of a two-stage procedure.

Possible Complications

  • abcess formation

  • leakage at the gastric staple line

  • infections

  • injury to abdominal organs

  • incisional hernia

  • stomach ulcer

  • inadequate weight loss

  • intestinal blockage
