CAMBEROS-SOLIS, R.; JIMENEZ-CRUZ, A.; BACARDI-GASCON, M.  and  CULEBRAS, J. M.. Long-term efficacy and safety of Roux-en-Y gastric bypass and gastric. Nutr. Hosp. [online]. 2010, vol.25, n.6, pp.964-970. ISSN 1699-5198.

Background: Bariatric surgery has increased substantially in the last years. However, there are controversies of the long-term efficacy and safety. Objective: To evaluate the long-term efficacy and safety of Roux-en-Y gastric bypass (BGRY) and gastric banding (Band) in randomized controlled trials and cohort studies. Methods: We searched for randomized controlled trials and cohort studies of BGRY and Band, with a follow-up > 48 months, with description of weight loss, complications and mortality. Results: Four randomized trials and one cohort study met the inclusion criteria. Mean weight loss was greater with BGRY (27%-39%) than with Band (13%-35%). In both procedures the complication rate is high. Second operation rate is higher with Band. Conclusions: The outcomes observed from this revision are not sufficient to generalize the efficacy and safety of bariatric surgery to population attended at different health care systems.
