Stomach Sleeve Surgery
Stomach Sleeve Surgery
Stomach sleeve surgery is one of the stomach weight loss surgeries. This procedure has several other medical names which include vertical sleeve gastrectomy, gastric sleeve resection, gastric sleeve surgery, tube gastrectomy, sleeve gastrectomy and laparoscopic sleeve gastrectomy.
Stomach sleeve surgery is performed on people who are extremely overweight with a BMI (body mass index) of over 40. A healthy BMI is between 18.5 and 24.5. A person with a BMI of 25 to 29.9 is considered overweight and with a BMI greater than 30 is considered obese.
This procedure is performed either as a standalone surgery or as the first of two surgeries. The second surgery is usually a duodenal switch or a gastric bypass. The two surgeries, duodenal switch and gastric bypass, are extremely risky if performed on a person who is extremely obese. It is for this reason that stomach sleeve surgery is performed first to allow the patient to lose a significant amount of weight before the second surgery is performed. This second surgery is performed when weight loss stops before the individual has attained a healthy weight.
Even when it is performed as a standalone surgery, stomach sleeve surgery is quite successful in helping individuals lose weight.
Stomach sleeve surgery is one of the newer weight loss procedures. It is a restrictive procedure as during the procedure the surgeon takes out approximately 85% of the stomach. He does this by removing a large portion of the stomach along the curve. What remains is a banana shaped tube or sleeve. Surgical staples are used to hold the edges together. The procedure does not alter the way food is digested as the intestines are not moved or bypassed.
This procedure is performed laparoscopically This means that the surgeon makes 2 or 3 incisions. He inserts a laparascope (which is a tube with a camera) in one of the incisions and the surgical instruments in the other incision.
After stomach sleeve surgery, weight loss is achieved because the reduced size of the stomach restricts the amount of food that can be eaten at any given time. The significantly reduced stomach size also has the effect of reducing the production of the hormone ghrelin that causes food craving and hunger sensations.
Stomach sleeve surgery has a number of advantages. It is a minimally invasive surgery which results in more than 50% weight loss in the first year after surgery. As there is no interference on how food is digested, there are fewer complications after surgery such as no dumping syndrome or malnutrition and there are fewer dietary restrictions imposed on the individual.
On the downside however, stomach sleeve surgery is irreversible. There is also the possibility that the stomach will stretch and again cause weight gain.
