Introduction: Bariatric surgery has proved to be effective in the management of morbid obesity. Our purpose was to compare the results obtained with adjustable gastric banding (GB) and Roux-en-Y Gastric Bypass (RYGB) during 2 years of follow-up after surgery, with regard to anthropometric parameters and related comorbidities.
Methods: We evaluated prospectively patients who underwent GB and RYGB between 2004 and 2010 and compared the evolution of anthropometric parameters, prevalence of type 2 diabetes mellitus (DM), hyperlipidemia and hypertension during 2 years of follow-up.
Results: 109 patients were submitted to bariatric surgery: 51 patients to GB (mean age 48.4±10.6, 84.3% women) and 58 to RYGB (mean age 45.2±9.2, 86.2% women). There were no statistically significant differences between the two groups regarding age, gender, weight, BMI, weight excess, BMI excess and prevalence of DM and hypertension before surgery; hyperlipidemia was more frequent in the RYGB group (46.6 vs 27.5%). Two years after surgery, percentages of excess weight and BMI losses were higher with RYGB (70.9±14.0 vs 38.5±22.3% and 83.7±7.8 vs 45.6±26.3% respectively). In the GB group, DM remitted in 75% of the patients, hypertension in 61.1% and hyperlipidemia in 64.3%; in the RYGB group, the respective percentages were 65, 61.1 and 85.2%.
Patients who didn’t achieve resolution of their comorbidities improved and needed less medication. The reduction of the prevalence of DM, hypertension and hyperlipidemia was significant in both groups and the post-surgical prevalence of those comorbidities was not significantly different between GB and RYGB.
Conclusions: Our study shows that RYGB results in higher weight and BMI loss than GB until the second year after surgery. Both procedures allow a significant resolution of obesity-related comorbidities.
