Effect of laparoscopic sleeve gastrectomy vs laparoscopic Roux-en-Y gastric bypass on weight loss in patients with morbid obesity. The SM-BOSS randomized clinical trial. JAMA 2018; 319: 255-265.

Published: 5th April 2018

Authors: Peterli R, Wölnerhanssen BK, Peters T, Vetter D, Kröll D , Borbély Y et al.

Conclusion

This study that included 240 patients did not demonstrate equivalence of percentage weight loss between laparoscopic sleeve gastrectomy (49 per cent) and laparoscopic gastric bypass (57per cent) after five years.
