The vertical sleeve gastrectomy, or sleeve gastrectomy, is a type of restrictive weight loss surgery. It causes weight loss by restricting the amount of food that a person can consume before feeling full.
Conventional Sleeve Gastrectomy is a surgical procedure that can be performed by minimally invasive surgery (Laparoscopically or robotically). The procedure reduces the size of the stomach to about 10% of its original volume and results in a limited capacity of food intake. In sleeve gastrectomy, the left side of the stomach is surgically removed by cutting and stapling. This results in a new stomach which is roughly the size and shape of a banana.
The surgery is typically performed on patients who are too heavy to have other types of weight loss surgeries with the expectation that a second surgery will be performed once weight has been lost, or on individuals who do not suffer from severe co morbidities and are young.
It does not require disconnecting or reconnecting the intestines
A silastic (GaBP) ring of 7.5 cm diameter is wrapped around the upper part of the sleeve. Adding a silastic band to sleeve gastrectomy increases the success rate by preventing gastric tube dilatation. This allows in maintenance of weight loss in the long term.
