Laparoscopic sleeve gastrectomy is a type of weight-loss/bariatric surgery. As the name suggests it can be performed through key-hole method (laparoscopy). In this technique 4 to 5 tiny cuts of half to one cm are made on the abdomen and the whole surgery is performed through these. Laparoscopic sleeve gastrectomy can also be performed in the scar-less manner through a single cut through the belly button. In this procedure, the stomach is divided longitudinally using surgical staplers and two-thirds of the stomach is removed. This results into a banana shaped stomach with a capacity of 60 to 100 cc.
Laparoscopic sleeve gastrectomy leads to weight loss by various mechanisms. First of all, it leads to restriction of food intake. After a sleeve gastrectomy in mumbai, the stomach can hold only 60 to 100 cc of food at one go. This reduces the amount of food that a person can have. As the stomach size is small, it also leads to feeling full sooner. The feeling of satiety sets in after eating even small quantities of food. After a Laparoscopic sleeve gastrectomy “hunger” sensation goes down significantly. This happens because the part of the stomach that is removed contains almost 80% of the hunger hormone called “ghrelin”. For the first year, most patients do not experience “hunger”. Hence, they are satisfied even after eating less food which is unlike being on a diet where one is constantly battling hunger and cravings. Food also tends to pass into the intestines faster than usual and this sets of a hormonal cascade that also aids in weight loss as well as helps in remission of type 2 diabetes. Ofcourse, there are other unknown mechanisms in addition to the ones listed above and all of these when put together lead to weight loss.
Laparoscopic sleeve gastrectomy leads to an excess weight loss of about 65 to 75% in 12 to 18 months. Patients also experience significant improvement in associated diseases like type 2 diabetes, high blood pressure, dyslipidemia, gout, PCOD, obstructive sleep apnoea, joint pains, liver disease etc. It also reduces the risk of venous thrombo-embolism and heart disease in the long term. Laparoscopic sleeve gastrectomy leads to a significant improvement in the quality of life of the patient.
In the long term the main issues observed with a laparoscopic sleeve gastrectomy are acid reflux and weight regain. However, obesity is a chronic progressive disease and as with any weight loss procedure, regular follow up with the bariatric team is the key to success after a laparoscopic sleeve gastrectomy. It is extremely important to follow a healthy lifestyle and a good exercise regime after a Laparoscopic sleeve gastrectomy.
