title: [The Mexican consensus on gastroesophageal reflux disease. Part I].
abstract: BACKGROUND
  The changes, advances, and new discoveries regarding different aspects of gastroesophageal reflux disease (GERD) have made it necessary to update the Mexican Consensus published in 2002.
  
  
  OBJECTIVE
  To elaborate a new Mexican Consensus on GERD.
  
  
  METHODS
  The general project coordinators selected six GERD experts to carry out an extensive review of the literature for the purpose of elaborating statements on the principal aspects of GERD. These were then placed under the consideration of specialists in the study of this disease. Definitive approval by all participants was reached using the modified Delphi method with three rounds of anonymous and iterative voting. The following scale was employed: A- in complete agreement; B- in agreement, but with minor concerns; C- in agreement, but with major concerns; D- in disagreement, but with major concerns; E- in disagreement, but with minor concerns; or F- in complete disagreement. Consensus was declared when 67.00% or more of the participants concurred on a category of agreement (A, B, or C).
  
  
  RESULTS
  A consensus was reached on 160 of the statements upon completion of the voting rounds, with 90.00% concurrence for the majority of them.
  
  
  CONCLUSIONS
  The 2011 Mexican Consensus on Gastroesophageal Disease is a practical and up-to-date consultation tool, providing the opinion of Mexican experts on all the new information available about this disease. It allows there to be homogeneity in diagnostic and therapeutic criteria, all of which serves to benefit our patients.
