Laparoscopic Sleeve Gastrectomy


Laparoscopic Sleeve Gastrectomy

One of the most widely performed weight loss surgeries

Laparoscopic-Sleeve-Gastrectomy---LIFECAREABSThis is a stomach-restrictive surgery, also popularly called the gastric sleeve or vertical sleeve gastrectomy (VSG).

This is preferred by patients as it  permits them to enjoy a greater variety of foods than in case of other obesity surgeries. Stomach function remains normal because all of the key components of the stomach are preserved. Anatomy is not altered in any other way and there is no intestinal bypass.

How It Works

The stretchy outer and upper part of the stomach, is permanently removed. A small “sleeve” or vertically-oriented tubular stomach (banana shaped) remains which is usually 6-7 inches long and half  an inch of the diameter. As the stomach capacity reduces by about a quarter, patients feel satisfied after eating about one tenth compared to their previous diet.

The outer portion of the stomach which is removed includes the tissue responsible for producing ghrelin, the hunger stimulating hormone. This drastically reduce the patients’ hunger and  hunger and food intake.

The results

The result of this procedure is a considerably smaller stomach, with all of the key structural elements of the stomach and intestines (the antrum, the pylorus and the nerves) preserved. The smaller stomach functions normally, quite similar to the previous stomach. Hence, patients can indulge and enjoy almost a normal diet and wide variety of foods (in much smaller quantities) with no side effects.

Weight loss is easy, quick and predictable, mainly achieved by the reduced amount of food that is consumed. With this operation there is no intestinal bypass or malabsorption.

No risk of “dumping” syndrome triggering nausea, cramping, diarrhea, sweat, vomits and  palpitations. This syndrome generally follows when a patient consumes carbs or sugar or eats too quickly. As the pyloric valve is preserved, it enables more physiologic emptying of solid foods from the stomach and tolerance for a greater variety of foods.

Major co-morbidities like diabetes, sleep apnea, hypertension, high cholesterol and depression are either resolved or show substantial improvement.

A comparatively low-maintenance surgery, an appropriate option for obesity patients with a hectic lifestyle, professionals frequently travelling, or those planning future pregnancy, knee replacement etc.

Healthy eating habits and regular exercise regime post surgery play significant role in maintaining the weightloss achieved by bariatric surgery.
