Obesity is a very morbid condition that has several health consequences. Mild obesity is still controllable by nutrition and exercise. However as it advances it becomes more difficult because of metabolic changes, physical limitations, psychological effect and social inhibition. When exercise and dieting does not help control the weight bariatric surgery may help loose weight and bring a person back to ground Zero where he can start working on his lifestyle and maintain weight.
So What are the different procedures to reduce weight?
There are two ways it can help lose weight-
- Restrictive surgery: In these procedures, the stomach is made smaller. A section of your stomach is removed that helps to limits the amount of food it can hold and causes you to feel full.
- Malabsorptive surgery: Most of digestion and absorption takes place in the small intestine. Surgery to this area shortens the length of the small intestine and/or changes where it connects to the stomach, limiting the amount of food that is completely digested or absorbed.
Through food intake restriction, malabsorption or a combination of both, you can lose weight since less food either goes into your stomach or stays in your small intestine long enough to be digested and absorbed
Vertical Sleeve Gastrectomy
The Vertical Sleeve Gastrectomy (VSG) or Laparoscopic Sleeve Gastrectomy (LSG) is an emerging weight loss procedure. It involves reducing the size of the stomach only, without any intestinal bypass or artificial device.
Sleeve Gastrectomy OR Vertical Sleeve Gastrectomy OR Partial Gastrectomy
This procedure involves surgery on the stomach only (it is only a restrictive procedure) and does not involve the intestine (which would make it malabsorptive). It basically consists of making a stomach that (before surgery) looks like a pouch into a long tube, or “sleeve”. The sleeve gastrectomy procedure removes approximately 2/3 of the stomach, which provides for quicker satiety (sense of fullness) and decreased appetite. The smaller stomach sleeve restricts food intake by allowing only a small amount of food to be consumed in a single sitting.
Surgical Procedure and Hospital Stay: Over 98% of sleeve gastrectomies are performed laparoscopically, with an average of 5 small incisions.They all require full general anesthesia and about 1 to 1 ½ hours of surgical time. Most patients stay one or possibly two nights in the hospital.
How much weight loss is achieved?
The vast majority of patients lose 50 to 80% of their excess weight in the first 12 months.
However, stimulated in the past, purely restrictive operations have led to LESS long-term weight loss than the gastric bypass. The recent advances have the advantage over the older procedures in that it possibly eliminates most Ghrelin hormone production and helps to reduce the sensation of hunger that people have.
Advantages of the Vertical Gastrectomy Weight Loss Surgery
- The stomach is reduced in volume but tends to function normally so most food items can be consumed, albeit in small amounts.
- Eliminates the portion of the stomach that produces hor stimulate hunger (Ghrelin).
- By avoiding the intestinal bypass, the chance of intestinal obstruction (blockage), anemia, osteoporosis, protein deficiency and vitamin deficiency are almost eliminated.
- Very effective as a first stage procedure for high BMI patients (BMI>55 kg/m2).
- Can be done laparoscopically in patients weighing over 500 pounds.
