The Journal of the American Medical Association (JAMA) has released 4 new studies comparing the effects of various surgical and non-surgical weight loss treatments among patients with obesity.
Two of the 4 studies compared patient outcomes following various types of bariatric surgery—including laparoscopic banding, gastric bypass, or laparoscopic sleeve gastrectomy—with nonsurgical, medical obesity treatment and usual care.
The first study (N=8385, baseline median body mass index [BMI] 46 kg/m2) found that bariatric surgery was associated with a lower risk of all-cause mortality vs non-surgical treatment.1 The second study (N=1888, baseline BMI 44.2 kg/m2) found that bariatric surgery was associated with a decreased risk for obesity-related comorbidities but an increased risk for complications.2
The remaining 2 studies, the SLEEVEPASS Randomized Clinical Trial and the SM-BOSS Randomized Clinical Trial, specifically assessed the effects of laparoscopic sleeve gastrectomy (LSG) vs laparoscopic Roux-en-Y gastric bypass (LRYGB) on weight loss in patients with obesity.
The authors of the SLEEVEPASS trial (N=240) found that LSG was not equivalent to LRYGB in regard to percentage excess weight loss at 5 years,3 whereas the authors of the SM-BOSS trial (N=217, mean BMI 43.9 kg/m2) found no significant differences in excess BMI loss between both procedures.4
