SLEEVE GASTRECTOMY

1. Safer than gastric bypass operation with lesser complications 1-3% and low  mortality (0.1%)
2. Cheaper than  gastric banding operation
3. Decrease ghrelin secretion and thus, hunger sensation

1. The surgery once performed is irreversible
2. Possibility for gastroesophageal reflux

1. Better and faster weight reduction with 30 -35% decrease in body weight in the 1st year
2. Effective treatment for diabetes mellitus

1. Surgery more complicated with 1-5% complications and 0.3 -1% mortality
2. Trace mineral absorption deficiency, anemia and other complications; require long term iron, calcium, folic acid, vitamin B complex, etc. supplementation
3. Impossible to perform gastroscopy for early gastric cancer detection

1. The weight loss effect is better and faster than laparoscopic sleeve gastrectomy: about 30% to 35% of body weight can be reduced in the first year.
2. The treatment effect for diabetes in patients with mild obesity is better than that of laparoscopic sleeve gastrectomy.
3. The surgery is simpler than laparoscopic Roux-en-Y gastric bypass.

1. Postoperative complications may include bile reflux, anastomotic ulcers, and dumping syndrome.
2. Postoperative complications (6%) and mortality (0.3%) are higher than laparoscopic sleeve gastrectomy.
3. Risk of insufficient absorption of nutrients, leading to anemia, osteoporosis and other complications.
4. It is impossible to perform a gastroscopy on the lower part of the stomach after surgery, making it hard to detect diseases in this area.

1. This endoscopic procedure does not create skin wounds nor resect organs.     
2. After the procedure, most patients could resume normal activities in 1-3 days.     
3. Post-procedural gastroesophageal reflux or trace element deficiency problems are rare.

1. If the patient's living and eating habits have not improved, the weight loss effect of the procedure will be affected.
2. Besides, it’s challenging to detect early gastric cancer lesions through endoscopy in the folded area of ​​the stomach after the procedure.
