1. Laparoscopic Sleeve Gastrectomy – An Introduction
A relatively new development in the sphere of surgery, laparoscopic sleeve
gastrectomy aim at weight reduction. A restricitive procedure, this kind of
surgery brings down the size of the stomach and limits the intake of food. This
way it brings down the amount of food consumed and thereby bringing down
the weight of the patient.
Usually 55% to 75% of excess body weight is lost in the process. The results
no doubt varies from person to person. Laparoscopic sleeve gastrectomy
may bring down the appetite level of the patients as ghrelin ­ “the hunger
hormone” is also reduced.
The Process
The outer margin of the stomach is removed in order to bring down the food
intake. The surgery is named as sleeve gastrectomy as a sleeve of stomach,
almost the size of a banana, and pylorus (muscle which controls emptying of
food from stomach to the intestine) are left behind in the stomach.
As the size of the stomach is reduced, the patient fells full even after taking
fewer calories. Compared to gastric bypass surgery, sleeve gastrectomy is a
simpler process as no re­routing of the intestines is involved. Also it doenot
involve use of any banding device around the stomach.
Difference between gastric banding surgery and gastric sleeve surgery
1. In gastric banding surgery a small band is placed around the upper part
of the stomach. The original size of the stomach is not reduced due to
incision. Sleeve gastrectomy involves removal of a part of the stomach
itself. Thus unlike gastric banding it is not irreversible.
2. When it comes to dietary changes, though both these restrictive surgical
procedures recommend no water/ drinks between the meal gastric
sleeve surgery demands, five small meals in a day, and banding three
meals. Also after gastric sleeve surgery, you are supposed to lay down
horizontally after the surgery.
3. While both these types of surgeries bring down the amount of food

2. intake, in gastric banding the food digestion process is slow and creates
satiety in the patient. Gastric sleeve (also known as sleeve gastrectomy)
reduces the sensation of hunger itself in the patient.
Advantages and Disadvantages
One major advantage of this process is that the weight loss process is faster
compared to other related surgeries. Also the patient is less likely to be food
intolerant which is quite common with the gastric band surgery. But one major
disadvantage is that unlike the banding surgeries, this one is irreversible.
