Gastrotomy, also known as laparoscopic sleeve 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 150cc, 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.

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.
