Reoperations were common in all groups .
Reoperation rate was initially high but reduced markedly with improved b and and surgical and aftercare techniques .
Conclusion All current procedures are associated with substantial and durable weight loss .
More long-term data are needed for one-anastomosis gastric bypass and sleeve gastrectomy  .
Reoperation is likely to remain common across all procedures
Introduction Durability is a key requirement for the broad acceptance of bariatric surgery .
Weight Loss Outcome After Roux-en-Y Gastric Bypass: 10 Years of Follow-up
Background By su bmi tting obese people to surgical treatment , we hope they lose weight and stay slim . Long-term monitoring is essential to assess effectiveness of surgery . This study aims to evaluate weight loss over 10 years in an obese population undergoing b and ed Roux-en-Y gastric bypass ( B-RYGBP ) .  Methods The surgery was performed in 211 obese between May 1999 and December 2000 . This prospect i ve study evaluated excess weight loss ( % EWL ) and body mass index ( BMI ) during the period . We considered surgical treatment failure if % EWL was less than 50 % . Results We followed 54.9 % of the population ( 116 patients ) .  Patients ' % EWL was 67.6 ± 14.9 % 1 year after surgery , 72.6 ± 14.9 % after 2 years , 69.7 ± 15.1 % after 5 years , 66.8 ± 7.6 % after 8 years , and 67.1 ± 11.9 % after 10 years postoperatively . Surgical treatment failure occurred in 16 patients ( 14.6 % ) over 10 years . Conclusions B-RYGBP is a good technique to promote and maintain weight loss 10 years after surgery with low failure rate
