The laparoscopic sleeve Gastrectomy procedure (also called vertical Gastrectomy, Greater Curvature Gastrectomy, Parietal Gastrectomy, Gastric Reduction and even Vertical Gastroplasty) is relatively a newcomer to the field of obesity surgery but is emerging as a procedure that is becoming increasingly popular worldwide. It is suitable produce for those who are classed under severely obese.
It causes weight loss by restricting the amount of food that can be eaten without any bypass of the intestines or malabsorption. This is a procedure in which the stomach is stapled together to form a slim tube or a sleeve approximately the same diameter of the oesophagus and the duodenum. The part of the stomach along the medial (lesser) curvature, which is in continuity with the food pipe (esophagus), is retained as the tube and the part outside the tube, which is the greater curvature of the stomach and the fundus is removed. It reduces the stomach to 20% of its original capacity. The holding capacity of the stomach is thereby drastically reduced.
The food intake is restricted but is absorbed normally. Hence the patient does not have to rely on daily supplementation.
- Dramatic weight loss is the first and the most important weight loss.
- The stomach is reduced in volume but tends to function normally so most food items can be consumed, though in small amounts.
- The excess stomach volume is removed. This possibly eliminates most Ghrelin hormone (secreted from the fundus of the stomach and stimulates hunger) production and helps to reduce the sensation of hunger these people have.
- As there is no bypass of the intestinal segment involved, absorption of minerals (calcium, iron) and vitamins does not suffer and it is not necessary to supplement these minerals and vitamins in the diet as is essential after the gastric bypass.
- It will reduce your risk of developing co-morbidity such as heart disease, stroke or liver disease: if you already have one or more of these obesity-related conditions then these will improve dramatically. In some cases the condition will disappear altogether.
- Potential for inadequate weight loss or weight regain. While this is true for all procedures, it is theoretically possible more with procedures that do not have an intestinal bypass.
- Soft calories such as ice cream, milk shakes, etc can be absorbed and may slow down the process of weight loss.
- Because the stomach is removed, it is not reversible.
There are many surgical methods to lose weight, this one is a relatively new method and a good one as it restricts the amount of food. If you can spend enough, then this could be your secret soon!
