title: [Value of endoscopy in the diagnosis of postoperative gastritis caused by alkaline reflux].
abstract: OBJECTIVE
  A long term retrospective study comparing endoscopic lesions and their relationship with symptoms and histological lesions of postoperative Alkaline Reflux Gastritis (ARG) between partial gastrectomy Billroth II (n = 25) and the Roux-en-Y (n = 36) is presented.
  
  
  METHODS
  In patients operated on with both techniques the clinical, endoscopic and histological aspects are studied.
  
  
  RESULTS
  The patients operated on with the Billroth II technique present a higher frequency of bile in the gastric remnant and mucosal lesions in the endoscopic study (p < 0.001) compared with the Roux-en-Y group. Bile and mucosal lesions on the gastric stump are more common with symptoms and histological lesions of postoperative ARG.
  
  
  CONCLUSIONS
  The endoscopic evaluation is a valid and reliable examination in the diagnosis and follow up of postoperative ARG.
