title: [Appropriate use of diagnostic esophagogastroduodenoscopy and its relation with positive results].
abstract: BACKGROUND
  Upper gastrointestinal endoscopy is a sensitive and safe procedure, but expensive and with certain risks. The range of inappropriate use of upper gastrointestinal endoscopy in open access system is between 5.6 to 61.7%. In our department we use restricted access system.
  
  
  OBJECTIVE
  To determine the accuracy of Gastrointestinal Endoscopy American Society guidelines in the diagnosis through the upper gastrointestinal endoscopies performed in a reference hospital setting with restricted access.
  
  
  METHODS
  We review requests for diagnostic upper gastrointestinal endoscopies and their reports between March 1st 2003 and February 29th 2004. It was defined as an appropriate diagnostic esophagogastroduodenoscopy which followed the American Gastrointestinal Endoscopy society guidelines. It was done statistical descriptive analysis.
  
  
  RESULTS
  A total of 3033 requests and reports of upper gastrointestinal endoscopies were reviewed. The proportion of clinical diagnoses that followed the guidelines was 74.3%. We found a 56.3% of abnormal positive endoscopy findings, concordance between clinical diagnosis and abnormal positive endoscopy findings was 46.8%.
  
  
  CONCLUSIONS
  The proportion of upper gastrointestinal endoscopies that follow the American Gastrointestinal Endoscopy Society guidelines in our restricted access system is low.
