title: [Long-term results of laparoscopic gastric bypass in patients with morbid obesity. a prospective study of 508 cases].
abstract: BACKGROUND
  Although there are publications on the short-medium term results of gastric bypass, publications of long-term results are very limited and the results are less documented.
  
  
  METHODS
  In this article we present the experience of the same surgical team with laparoscopic gastric bypass over 7 years, with a follow-up of 97% of the patients. From March 2000 until May 2007, 508 laparoscopic gastric bypasses were performed by the same surgical team.
  
  
  RESULTS
  Of the 508 patients who were subjected to laparoscopic gastric bypass, 353 were women (69.5%) and 155 were men (30.5%), with a mean age of 40 years (16-71), a mean pre-operative weight of 131.3 +/- 24.5 kg (80-230) and a mean BMI of 48.3 +/- 7 (34-78). There were early complications (< 30 days) in 14.7% of the patients and delayed complications (> 30 days) in 7.3%. The mean operation time was 125.8 +/- 35.6 minutes (60-300). The mean hospital stay was 3 +/- 2.6 days (1-40). The mortality of the series was 0.8%. The EWL and BMI loss at 3 and 5 years was 77.8% and 75.1% and 82.7% and 79.8%, respectively.
  
  
  CONCLUSIONS
  Laparoscopic gastric bypass is an effective technique for the long-term treatment of morbid obesity, with a low number of complications, low mortality, excellent weight loss and recovery or improvement of the comorbidities associated with these patients.
