Laparoscopic Sleeve Gastrectomy

 Laparoscopic Sleeve GastrectomyLaparoscopic Sleeve Gastrectomy (LSG) is emerging as one of the most popular bariatric surgeries world over. It remains the most commonly performed bariatric procedure that we perform at CODS. It is an irreversible procedure that curtails the size of the stomach by surgically removing two thirds of it, making it roughly the size and shape of a banana. Since the procedure constricts the stomach size and also eliminates 'ghrelin', the hunger inducing hormone, you will feel satiated with smaller portions and lose weight quite quickly.

Is this procedure suitable for you? Read the Eligibility for surgery section to find out.

The advantages

Some of the advantages that Laparoscopic Sleeve Gastrectomy has over other bariatric procedures are:

  • The nerves of the stomach and the outlet valve (pylorus) are not altered, preserving the function of the stomach. The rest of the gastrointestinal tract anatomy is not altered, so the food ingested follows the normal course. This results in less chance of developing lack of vitamins and minerals and eliminates dumping syndrome.
  • This procedure significantly decreases hunger by removing that part of the stomach that produces the main stimulating hormones.
  • It minimizes the chances of developing ulcers.

Eligibility for surgery

Laparoscopic Sleeve GastrectomyThis procedure is recommended:

  • If you are morbidly obese
  • If you are super obese and are considered high risk to undergo the gastric bypass procedure
  • If you do not want to do lap band because you're not particularly comfortable having a foreign body placed inside you
  • If you are looking to lose in excess of 70 - 80% of your excess weight and have co-morbidities associated with obesity


How long is the surgery? Is it painful?

Laparoscopic Sleeve Gastrectomy is a fairly simple procedure that takes about 45 minutes to an hour to perform and requires only a night's stay in the hospital. During the surgery you will be under general anesthesia and won't feel any pain. But there is a minimal amount of discomfort for the first 3-4 days post the surgery which can be negated by taking painkillers.

Are there any side effects or complications possible?

There are no side effects, however it restricts the amount of food you can consume post surgery. Since the procedure does not alter your stomach's mechanism drastically there are no long term complications either. In fact the total complication rate is less than 1% which is similar to other procedures, like a gall bladder or hernia surgery.

How much weight will I lose?

You will lose about 60 - 80% of your excess body weight over a period of one and a half years. Out of this the fastest weight loss occurs within the first 3 to 4 months, after which the rate of weight loss slows down.

Do I need to take bed rest after the surgery?

We encourage you to walk on the same evening of the surgery as being active and mobile reduces the risk of deep vein thrombosis. You can return to work within a week. however it depends on your comfort level, most patients resume work within 4-5 days while few others prefer to rest for a week.

Will I regain weight after this surgery?

Yes you can if you are not careful with the intake of liquid calories as consumption of small frequent amounts of liquids could lead to increased caloric intake. Good healthy eating habits and regular exercise form the cornerstones of success after bariatric surgery.

Are there any dietary restrictions after the surgery?

You will need to be on a liquid diet for 15 days after the surgery. This is followed by 15 days of semi-solid foods and then you progress onto solids. Within 2 to 3 months you can have all kinds of foods though in limited quantities.

How does it help with my comorbidities?

Post the surgery there should be a marked improvement in your overall health especially with respect to obesity related co-morbidities such as type 2 diabetes, sleep apnea, gout, hypertension etc.
