Laparoscopic Sleeve Gastrectomy(LSG) is relatively a new procedure. This surgery can be done as a standalone procedure for people who don’t have much weight to lose, or for older people or as part of a staged operation. LSG is also called vertical sleeve gastrectomy or gastric sleeve procedure.
LSG is the only bariatric procedure that has no malabsorption like the RNY and DS. There are no foreign body issues like the Lap-Band does. The risk factors involved during the surgery is very low 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, hunger is affected because of the reduced capacity of Ghrelin production, a substance that plays a crucial role in how you feel and relieve hunger.
Preservation of Pyloric Valve
An important factor is that it preserves the pylorus valve, the valve which controls emptying of your stomach. This valve acts as “natures band” as it allows the food you consume to hold up for a while in your stomach and makes the person feel full.
Laparoscopic Sleeve Gastrectomy(LSG) Procedure
The sleeve gastrectomy procedure is performed using a laparoscopic. The process involves making 5 or 6 small incisions around the abdomen, and it takes one to two hours. In this procedure, a probe with a video camera head called laparoscope and other long instruments are sent through these small incisions to slice the stomach.
During the gastric sleeve procedure, nearly 75% – 80% of your stomach is removed, leaving a small portion of the stomach. No intestinal parts are removed nor bypassed during the sleeve gastrectomy.
Advantages Of Laparoscopic Sleeve Gastrectomy
After the LSG procedure, most of the people start to lose weight between 40% and 70% in 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 or cured after sleeve gastrectomy surgery.
