Mixed
Both bariatric surgery (RYGB/SG) and structured medical treatment (VLED) result in similar safety profiles regarding hospitalization, need for further surgery, and mortality at 2-year follow-up, despite differences in weight loss magnitude.
Safety outcomes, including hospitalization and mortality, are comparable between bariatric surgery and structured medical treatment at 2 years. This suggests that for many patients, the higher efficacy of surgery does not come with a proportionally higher immediate safety risk compared to medical management.
The need for surgery and in-hospital treatment during the follow-up period was similar between the three treatment groups... Two patients died in both the MT and the RYGB groups, and there were no fatalities in the SG group (p=0.59).
Why this rating
Large cohort, but non-randomized design may introduce selection bias (e.g., sicker patients might be steered toward surgery or medical management based on clinician judgment).

More from this paper
- Bariatric surgery (RYGB or SG) produces significantly greater weight loss and higher treatment success rates than structured medical treatment including very low energy diet (VLED) at 2-year follow-up, though both interventions improve cardiovascular risk factors and safety profiles similarly.Good
- Baseline anthropometry (initial BMI/weight) is the strongest predictor of treatment success for both surgical and medical obesity interventions, followed by psychiatric health and lifestyle factors.Good
