Laparoscopic sleeve gastrectomy is one of the most common bariatric/ weight loss surgery being performed all over the world. During this surgery, a part of the stomach (greater curvature) is removed with the help of surgical staplers leaving a narrow gastric “tube” or “sleeve”. No intestines are removed or bypassed during the sleeve gastrectomy. This surgery is performed laparoscopically (key hole/ minimal access) and is irreversible.
Patients usually lose about 70% of their excess body weight within eighteen months of the surgery. Many obesity-related co-morbidities improve or resolve after bariatric surgery. Diabetes, hypertension, obstructive sleep apnoea, and abnormal cholesterol levels are improved or cured in more than 75% of patients undergoing LSG.
Patients are encouraged to walk from the day of the surgery itself. Most patients are comfortably up and about the next morning and can take a bath themselves.
They are on a liquid diet for two weeks after the surgery and then progress to soft diet for the next two weeks. From thereafter, they are on a normal diet.
After eating a small amount of food, you will feel full very quickly and continue to feel full for several hours. Sleeve gastrectomy may also cause a decrease in appetite.
There are certain risks that are common to any laparoscopic procedure such as bleeding, infection, injury to other organs, or the need to convert to an open procedure. There is also a small risk of a leak or bleeding from the staple line used to divide the stomach. These problems are rare and major complications occur less than 1% of the time.
Some patients also complain of nausea and vomiting. However, most of these symptoms settle down with time.
