title: [Preliminary results of horizontal gastroplasty with Roux in Y anastomosis in patients with severe and morbid obesity].
abstract: BACKGROUND
  Morbidly obese subjects have a high incidence of complications. The poor results of dietary treatments, has prompted the search of new therapies for obesity and among these, surgical procedures.
  
  
  OBJECTIVE
  To report the long term results of horizontal gastroplasty with Roux en Y anastomosis in morbidly obese subjects.
  
  
  METHODS
  Fifty patients with an initial body mass index of 41.3 +/- 6 kg/m2 have been subjected to a horizontal gastroplasty with Roux en Y anastomosis. During the study period, surgical techniques were modified, reducing the gastric pouch size, adding a truncal vagotomy, cholecystectomy, and increasing the length of the Roux en Y loop from 70 to 100 cm. Twenty five patients have been followed for two years.
  
  
  RESULTS
  There was no operative mortality and one patient had an anastomotic leak that required 35 days of hospitalization. During follow up, in one patient, the stapled suture line loosened. After two years of follow up, weight decreased from 112 +/- 19 to 77.2 +/- 14 kg.
  
  
  CONCLUSIONS
  Horizontal gastroplasty with Roux en Y anastomosis achieved an adequate weight loss with a low rate of complications in this group of morbidly obese subjects.
