Minimally invasive gastrectomy, also known as laparoscopic gastrectomy, is based on the principle that the large curvature of the stomach is vertically cut by laparoscopy, so that the stomach forms a small gastric sac of about 1.50 cc, which can hold about 4-5 ounces of food. Its advantage is that there is no need to put foreign bodies into the body, and the weight loss effect is remarkable. Because surgery will cut off 80% of the stomach volume, in addition to reducing food intake, it will also reduce the secretion of ghrelin, a hormone that stimulates appetite, so appetite will also decline. About 10- 15 body mass index or 70% excess weight can be lost within two years after operation. For people with high body mass index and difficult to reduce their food intake, gastrectomy can achieve ideal weight loss effect.

Principles of gastrectomy:

The principle of gastrectomy is to vertically cut the great curvature of the stomach by laparoscopy, so that the stomach can form a small gastric sac of about 150cc, which can hold about 4-5 ounces of food. Because the stomach volume is reduced, the food intake is reduced fundamentally, and the absorption of the stomach is reduced, thus inhibiting the growth of abdominal fat and body obesity; So as to reduce the patient's overweight weight by about 70%. Its advantage is that there is no need to put foreign bodies into the body, and the weight loss effect is remarkable. Because surgery will cut off 80% of the stomach volume, in addition to reducing food intake, it will also reduce the secretion of ghrelin, a hormone that stimulates appetite, so appetite will also decline. About 10- 15 body mass index or 70% excess weight can be lost within two years after operation. For people with high body mass index and difficult to reduce food intake, sleeve gastrectomy can achieve ideal weight loss effect.

Advantages of gastrectomy:

1. The weight loss effect is similar to that of gastric bypass surgery and higher than that of gastric band.

2. No foreign body implantation, no risk of rupture, leakage and wear.

3. No adjustment is needed

4. The edible quality is higher than that of gastric band.

5. The safety is higher than that of gastric bypass surgery.

6. Does not affect the absorption of vitamins and minerals.

7. Less long-term side effects

8. The operation recovered quickly.

9. If weight loss is not ideal, it can be converted into gastric bypass surgery.

10. It can also be performed by laparoscopic minimally invasive method.
