A meta-analysis of bariatric surgery has been published in JAMA Surgery. The analysis covers 164 studies covering 161,756 patients with a mean age of 44.5 and BMI of 45.6. The researchers found the within 30 day mortality rate was 0.08% and beyond 30 days 0.31%. BMI loss at 5 years was 12-17. Complication rate was 17%. The re-operation rate was 7%. Adjustable gastric banding had lower mortality and complication rates but the reoperation rates with higher and weight loss less substantial compared to gastric bypass. The authors conclude that the mortality rate was lower than reported in previous meta-analyses.
