Laparoscopic Sleeve Gastrectomy(LSG) is relatively a new procedure. It is also termed as vertical sleeve gastrectomy or gastric sleeve procedure. The surgery involves removing the outer margin of the stomach to restrict food intake, leaving a sleeve of the stomach of the size and shape of a banana. This surgery also performed as a standalone procedure for people who wants to lose less weight, or for older people.
Gastric sleeve is the only bariatric procedure which has no malabsorption like other bariatric procedures. It is a simpler procedure and the risk factors involved is also very low during the surgery compared to other procedures. The recurring rate is also extremely low that there is no need for another operation in the future compared to other bariatric procedures.
Weight Loss Mechanism
The size of the stomach will be reduced to about 60cc in the volume that results in a dominant and restrictive weight loss. As a result, people feel full after having a small amount of food. Therefore they start to lose weight because they eat less.
The procedure also shows significant effects on the hunger mechanisms that make the weight loss seen even better with a small stomach pouch. Favourably, your hunger gets reduced due to low Ghrelin production, the substance that plays a vital role in how you feel and relieve hunger.
Preservation of Pyloric Valve
The important factor to be noted in this procedure is that it preserves the pylorus valve, which controls the emptying of the stomach. This valve acts as “natures band” as it regulates the food you eat to hold up for a while in the stomach and makes you feel full.
Laparoscopic Sleeve Gastrectomy(LSG) Procedure
Sleeve gastrectomy is performed with the help of laparoscopy. The process involves making 4 to 5 small incisions around the abdomen. A laparoscopic probe with a camera head is inserted through one of the incision. Other surgical instruments are inserted through the other small incisions to slice the stomach.
During this procedure, nearly 75% – 80% of your stomach is removed, leaving a small portion of the stomach. No intestinal parts are removed nor bypassed in the sleeve gastrectomy surgery.
Advantages Of Laparoscopic Sleeve Gastrectomy
After this procedure, most of the people might lose weight around 40% and 70% within the first two years. Some studies practically proved that 75% of people with obesity-related problems like diabetes, hypertension, high BP, sleep apnea and high cholesterol are improved after sleeve gastrectomy surgery.
