Laparoscopic Roux-en-Y gastric bypass: significant long-term weight loss, improvement of obesity-related comorbidities and quality of life.

Abstract To present long-term results of a large series of patients submitted to laparoscopic Roux-en-Y gastric bypass (RYGBP) for morbid obesity. Reports on long-term results of RYGBP are scarce and focus primarily on weight loss. Our aim is to provide mid- to long-term data of RYGBP, with detailed results on weight loss, evolution of comorbidities and quality of life, also using the BAROS score. All patients who underwent a primary RYGBP for morbid obesity in our 2 hospitals between 1999 and August 2008 were included. Data were collected prospectively in a computerized database, and reviewed for the purpose of this study. A total of 379 patients were included in the analysis of long-term results, 282 women, and 97 men, with a mean BMI of 46.3 kg/m². After 5 years, 74.9% of the patients achieved an excess weight loss of at least 50%, with a mean of 62.7% and 76.8% achieved a BMI
