Sleeve Gastrectomy VS Gastric Bypass
Why is it Called the Sleeve Gastrectomy?
The Sleeve Gastrectomy surprisingly is actually the same procedure as the vertical sleeve gastrectomy, and lap sleeve The Sleeve Guide seeks to tie the naming conventions together to avoid confusion, and clarify information for patients. The origins of the naming of the sleeve gastrectomy actually result from the shortening of the vertical sleeve gastrectomy.
Originally the sleeve gastrectomy was used as a staging procedure for individuals whose BMI was too high to have a Roux-en-Y Gastric Bypass or Duodenal switch done safely. Thankfully due to advances in care and new studies, the sleeve gastrectomy has proven itself to be effective as a primary bariatric procedure.
What is the Sleeve Gastrectomy?
The Sleeve Gastrectomy is a bariatric surgical procedure that is recommended for individuals that suffer from morbid obesity that has failed to be remedied by traditional methods of weight loss.
Weight loss in the sleeve gastrectomy focuses on the restrictive method that removing nearly 85% of the stomach that is responsible for producing ghrelin, the hormone that causes hunger. This restriction is beneficial in allowing for the weight loss of roughly 60-70% of excess body weight brought on by morbid obesity. Excess weight can be lost within the first 18-24 months and is sustainable with good dieting and exercise.
Is the Sleeve Gastrectomy Good For Me?
In 1991 the National Institute of Health had a Consensus meeting on the effectiveness and indications for bariatric surgery (ex. sleeve gastrectomy). From this meeting it was determined that surgery was indicated for an individual that:
a. Had a BMI of 40 or greater.
b. Had a BMI of 35 – 39 and also suffered from a co-morbid condition example include but are not limited to hypertension, diabetes, and sleep apnea.
c. The benefit from surgery outweighs the relative risk of the procedure.
Since 1991 discussions have looked at the lowering of the BMI requirement and allowing certain bariatric procedures, the laparoscopic sleeve gastrectomy and laparoscopic roux-en-y gastric bypass, to be performed because of their affect on diabetes (regardless of the individuals BMI), at this time no formal decision has been made.
As of February 16th, 2011 the FDA has approved the lap band to allow for placement in individuals 30-35 BMI depending on a patients conditions. This news presents mounting evidence of the health benefits of bariatric procedures in general and could see its way toward the gastric sleeve.
