Abstract BACKGROUND: By submitting 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 banded Roux-en-Y gastric bypass (B-RYGBP). METHODS: The surgery was performed in 211 obese between May 1999 and December 2000. This prospective 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.
