title: [Complications of conventional and laparoscopic gastric bypass. Prospective and comparative study].
abstract: BACKGROUND
  Roux-en-y gastric bypass for the management of morbid obesity is currently the safest and more efficient treatment option. the laparoscopic era has shown its benefits in this type of surgery, so some authors advocate its implementation in a practical systematic way. all of which has lead in recent years to the unavoidable change in the surgical approach.
  
  
  OBJECTIVE
  To evaluate and compare the complications of laparoscopic gastric bypass and the conventional one in patients with morbid obesity. Application site: self-administration national university hospital.
  
  
  METHODS
  Comparative, prospective no randomized study.
  
  
  METHODS
  Between 2002 and 2011, 420 morbidly obese patients received surgical treatment for the obesity either open (167) or laparoscopic (253) surgery
  
  
  RESULTS
  Early postoperative complication rate was 4% in the lbg and 34% in the cbg (p < 05, 95%ci 22-38), mostly represented by seromas (25%) and wall abscesses (5.4%). the percentage of late postoperative complications was 2.8% in the lbg group and 9.6% in the cbg (p=0.004, 95%ci 1.4-12.2), the most frequent being incisional hernias (7.18%).
  
  
  CONCLUSIONS
  According to our experience and consulted literature, laparoscopic gastric bypass is a safe, reproducible and with a lower rate of both early and late complications than cbg, and so we consider and offer lbg as the ideal technique for the treatment of patients with morbid obesity.
