Sleeve gastrectomy
The operation was mainly to reduce the stomach volume, completely free the gastric fundus and the greater curvature of the stomach, use the 36Fr gastric tube as the internal support of the stomach, 2~6cm away from the pylorus as the starting point of the greater curvature of the stomach, cut upward, completely remove the gastric fundus and the greater curvature of the stomach, completely preserve the cardiac, and make the residual stomach look "banana".
The reduced stomach volume is 60~80mL, and the original gastrointestinal tract anatomy is maintained,
which can improve the glucose metabolism and other metabolic indexes of obese patients.
