VALEZI, Antonio Carlos et al. Weight loss eight years after gastric bypass. Rev. Col. Bras. Cir. [online]. 2011, vol.38, n.4, pp. 232-236. ISSN 0100-6991. http://dx.doi.org/10.1590/S0100-69912011000400006.
OBJECTIVE: To evaluate the effectiveness of banded Roux-en-Y gastric bypass in promoting weight loss after an eight-year follow-up. METHODS: Two hundred and eleven obese patients underwent Roux-en-Y gastric bypass with banding by the same surgical team. The study design was longitudinal, prospective and descriptive. The analysis of weight decrease in the postoperative period was based on the loss of excess weight in percentage and BMI. Failure was considered when patients lost <50% of excess weight. RESULTS: The loss of follow-up was 36.5%, therefore, 134 patients were included in this study. The loss of excess weight in global average rate in the postoperative period was: 67.6 ± 14.9% in the first year, 72.6 ± 14.9% in the second year, 69.7 ± 15.1% in fifth year and 66.8 ± 7.6 in eight years. Surgical treatment failure occurred in 15 patients (7.1%) over the period. CONCLUSION: Banded Roux-en-Y gastric bypass was effective in promoting and sustaining weight loss in the long term, with low failure rates.
