Randomized Clinical Trial of Laparoscopic Roux-en-Y Gastric Bypass Versus Laparoscopic Sleeve Gastrectomy for the Management of Patients with BMI < 50 kg/m2
Background Laparoscopic Roux-en-Y gastric bypass ( LRYGB ) is currently the gold st and ard bariatric procedure for the treatment of morbid obesity . Laparoscopic sleeve gastrectomy ( LSG ) is a relatively innovative procedure which has been increasingly applied lately as a sole bariatric procedure . A r and omized trial was conducted in a Greek population to evaluate perioperative safety and 3-years results . Methods Sixty patients with body mass index ( BMI ) ≤ 50 Kg/m2 were r and omized to LRYGB or LSG .  Patients were monitored for 3 years postoperatively and throughout the study period weight loss , in terms of percent excess weight loss ( % EWL ) , early and late complications , improvement of obesity related comorbidities and nutritional deficiencies were compared between groups . Results There was no death in either group and there was no significant difference in early ( 10 % after LRYGB and 13 % after LSG , P > 0.05 ) and late morbidity ( 10 % in each group ) . Weight loss was significantly better after LSG in the first years of the study and at 3 years % EWL reached 62 % after LRYGB and 68 % after LSG ( p = 0.13 ) . There was no significant difference in the overall improvement of comorbidities . Nutritional deficiencies occurred at the same rate in the two groups except to vitamin B12 deficiency which was more common after LRYGB ( P = 0.05 ) . Conclusion LSG and LRYGB are equally safe and effective in the amelioration of comorbidities , while LSG is associated with fewer postoperative metabolic deficiencies , without the need of supplementation . Furthermore , LSG is a promising bariatric procedure , equally effective to LRYGB at 3 years follow up on weight reduction
