Laparoscopic Gastric Sleeve Reduction
The laparoscopic sleeve gastrectomy is a bariatric procedure in which the surgeon removes approximately 85% of the stomach, shaping the remaining stomach into a tube or “sleeve”. It can be used as a first stage operation prior to a gastric bypass or as a definite procedure.
What are the advantages of the Laparoscopic Sleeve Gastrectomy?
During the laparoscopic gastric sleeve the nerves of the stomach and the outlet valve (pylorus) are not altered, preserving the function of the stomach. Other advantages:
- The rest of the gastrointestinal tract anatomy is not altered, so the food ingested follows the normal course. This results in less chance of developing lack of vitamins and minerals and eliminates dumping syndrome.
- The procedure decreases significantly the hunger by removing the part of the stomach that produces the main stimulating hormones.
- Minimize the chance of developing ulcers.
- Fewer office visits that the Lap Band, since there is no need for band size adjustments.
How is the Laparoscopic Sleeve Gastrectomy performed?
In the laparoscopic sleeve gastrectomy the stomach is divided along its vertical length in order to create a slender pouch. The excess stomach is removed. The purpose is to limit the amount of food ingested at any give time (restrictive operation), without altering the normal absorption of the vitamins and minerals.
How is a laparoscopic procedure performed?
Just like for the Roux-en-Y gastric bypass, and the adjustable gastric band, the procedure is conducted in a minimally invasive fashion thru several small incisions (laparoscopically). As in the laparoscopic gastric bypass, harmless gas, camera (laparoscope) and instruments are utilized.
Who is a good candidate for this procedure?
The procedure is particularly indicated for patients who are at high medical risk for bypass procedures, have very high BMI, or complex surgical history. Patients interested in the gastric banding procedure may also want to consider the sleeve gastrectomy to avoid the potential risks of a foreign body.
