Gastric Sleeve dates back to 1999 and early 2000s. Dr. Michel Gagner, Mount Sinai Hospital in New York, performed the first gastric sleeve procedure in 1999. In 2000, Dr. Gagner proposed the gastric sleeve as a first step in the duodenal switch procedure, a weight loss surgery reserved for highly obese patients. In 2003, Dr. Gagner  proposed the gastric sleeve as the first part of the Roux-en-Y gastric bypass procedure. Since then, more and more bariatric surgeons have become aware of the advantages of such surgery:

  • Low Complications
  • Less Invasive
  • Low Maintenance Required
  • No Intestinal Changes
  • No Malabsorptive Issues
  • Signification Reduction in the Hunger Hormone, Ghrelin

Originally just seen as restrictive weight loss procedure, like Lap-Band, gastric sleeve is now considered a “mix” procedure, because of appetite reduction. The Ghrelin is a amino acid that helps stimulate hunger, also known as Growth Hormone Release Inducing (Acronym for Ghrelin). Discovered in 1996, Ghrelin induces appetite, and the sleeve effectively reduces that hormone by 90%. This reduction directly correlates to the level of appetite patients experience, and data on 5 and 6 year post-op patients confirm the levels of Ghrelin remain low.
