title: Vertical banded gastroplasty-gastric bypass in Mexican patients with severe obesity: 1 year experience.
abstract: BACKGROUND
  Different surgical alternatives for the treatment of severe obesity have been described. The two most common surgical procedures are the Vertical Banded Gastroplasty (VBG) and the Roux-en-Y Gastric Bypass (GBP).
  
  
  METHODS
  This work describes the results seen during the first 12 months after a surgical technique named Vertical Banded Gastroplasty-Gastric Bypass on 221 Mexican patients with severe obesity operated on between March 1993 and August 1996.
  
  
  RESULTS
  73.3% of the patients were female with an average age of 33.4 years with a standard deviation (SD) of 10 years. The initial mean overweight was 62.2 kg (SD = 26.5 kg). The percentage of ideal weight was 202.3% (SD = 39.4%). The initial body mass index (BMI) was 44.9 kg/m2 (SD = 9.1). The average of excess weight loss in a year was 81.2% (SD = 15.6%) and the BMI was lowered to 26.7 kg/m2 (SD = 5.9). An interesting finding was that the greater the initial overweight, the lesser the resulting weight loss (r = 0.57, P < 0.001).
  
  
  CONCLUSIONS
  The procedure was fairly easy to perform. The results were excellent in terms of weight loss and postoperative complications. It is an early experience and the long-term results are still inconclusive; regular check-ups should indicate the procedure's long-term effectiveness.
