Gastric Sleeve Weight Loss Surgery

Laparoscopic sleeve gastrectomy (gastric sleeve) is a bariatric surgery in which the surgeon removes approximately 85 percent 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.

Gastric Sleeve Gastrectomy Procedure

During a gastric sleeve procedure, the stomach is divided along its vertical length in order to create a slender pouch. The excess stomach is then removed. The purpose of a gastric sleeve is to limit the amount of food ingested at any given time without altering the normal absorption of the vitamins and minerals.

Benefits of a Gastric Sleeve

With a gastric sleeve procedure, the nerves of the stomach and the outlet valve (pylorus) are not altered, preserving the function of the stomach.

Other advantages of a gastric sleeve include:

  • 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 significantly decreases hunger sensations by removing the part of the stomach that produces the main stimulating hormones.
  • It minimizes the chance of developing ulcers.
  • There are normally fewer office visits than with gastric banding, since there is no need for adjustment of the size of the band.
