Background: Bariatric surgery is the gold-standard treatment for morbid obesity because it has low morbidity rates in high-volume centers and generates long term sustained weight loss. Aim: To describe our experience in bariatric surgery since the creation of our bariatric program in 1992. Material and Methods: Retrospective analysis of all patients subjected to bariatric surgery from 1992 to December 2010. Data was obtained from the electronic institutional registry. The Procedures performed were open and laparoscopic Roux-en-Y gastric bypass (BPGA and BPGL, respectively), laparoscopic adjustable gastric band (BGAL) and laparoscopic sleeve gastrectomy (GML). Results: A total of 4943 procedures were performed, 768 (16%) BPGA, 2558 (52%) BPGL, 199 (4%) BGAL and 1418 (29%) GML. The number of procedures progressively increased, from 100 cases in 2000 to over 700 cases in 2008. Proportion of females and preoperative mean body mass index fluctuated between 69 and 79% and 35 and 43 kg/m(2), respectively, among the different procedures. Early and late complications fluctuated between 0 to 1% (higher on BPGA) and 3 to 32.7% (higher on BGAL), respectively. The excess weight lost at five years was 76.1% in BPGA, 92.5% in BPGL and 53.7% in BGAL. The figure for GML at three years was 73.7%. Conclusions: The complication rates of this series of patients are similar to those reported in large series abroad. BPGL is still the most effective procedure; however GML is an attractive alternative for less obese patients.
