The prevalence of SHPT is high in morbidly obese patients before bariatric surgery which is related to vitamin D deficiency. The prevalence of SHPT increased continually along with the time after bariatric surgery, especially in patients receiving SAGB, followed by RYGB. The supplementation of vitamin D and calcium have to be higher in bypass procedure, especially in malabsorptive procedure.

Laparoscopic gastric bypass facilitates immediate improvement in the glucose metabolism of inadequately controlled non-severe obese T2DM patients, and the benefit is sustained up to 2 years after surgery. The benefit is regulated by the decrease in insulin resistance, increase in early insulin response, and total insulin secretion to glucose load.

LSG is an effective obesity treatment to achieve significant weight loss after 24 months. Staple-line reinforcement is strongly recommended for laparoscopic sleeve gastrectomy to decrease complications.

The long-term result for weight loss after LAGB is unsatisfactory. The revision of failed LAGB to other bariatric surgeries is safe and can be performed in one stage with a low complication rate. Patients who underwent R-LSAGB had better weight loss results than the R-LSG or R-LRYGB patients.
