title: [Coverage of the gallbladder cancer prevention strategy in Chile: results from the 2009-2010 National Health Survey].
abstract: BACKGROUND
  In Chile, gallbladder cancer (GBC) is one of the most important causes of death and gallstone disease (GSD) is its main risk factor. Abdominal ultrasonography (AU) is used for the diagnosis of GSD and cholecystectomy is used to prevent it.
  
  
  OBJECTIVE
  To estimate GSD prevalence in the general population and to assess the diagnostic and therapeutic coverage of GSD as a preventive strategy for GBC in Chile.
  
  
  METHODS
  A standardized digestive symptoms questionnaire of the 2009-2010 Chilean National Health Survey was answered by 5412 adults over 15 years old. Self-reports of AU, GBD and cholecystectomies were recorded.
  
  
  RESULTS
  The prevalence of biliary-type pain was 7.1%. During the last five years, the prevalence of AU was 16%. GSD was reported in 20% of these tests and 84% of them were asymptomatic. The prevalence of AU was significantly lower in Araucanía region and among people with less than 12 years of education. Life cholecystectomy prevalence was 11% and reached 40% in people aged over 60 years. Women accounted for 75% of total cholecystectomies. Twenty-one percent of individuals who referred biliary-type pain, were studied with an AU. Only 60% of people with GSD confirmed by AU underwent a cholecystectomy.
  
  
  CONCLUSIONS
  GSD affects at least 27% of the Chilean adult population. Important deficits and inequities in GSD diagnostic and therapeutic coverage were identified.
