Epidemiology and risk factors for gallstone disease: Has the paradigm changed in the 21st century?

  • Eldon A. Shaffer
Article

Abstract

Gallstone disease is common and costly, creating over 700,000 cholecystectomies annually. Its complications consume approximately $6.5 billion in the United States. Surveys using noninvasive ultrasonography have identified its true prevalence and the associated risk factors. In developed countries, at least 10% of white adults harbor cholesterol gallstones; women have twice the risk, and age further increases the prevalence in both sexes. Gallstones reach epidemic proportions in the North and South American Indian populations, accompanied by an increased risk for gallbladder cancer. In contrast, the rate in sub-Saharan Africa and Asia is quite low. Obesity, a major risk factor, likely relates to insulin resistance (the metabolic syndrome). Evolution and circumstance in American Indians may have ironically selected those with "thrifty" genes that conserve energy. Our abundant access to food places us at the increased risk of obesity and cholelithiasis. The general rise in obesity in many countries raises the specter of heightened disease, best identified by epidemiologic studies.

This paper has collected the recent incidence, prevalence, mortality, and resource utilization of digestive and liver diseases in the United States from large publicly available national data bases (Division of Vital Statistics, National Center for Health Statistics, National Ambulatory Medical Care Survey 2000, and National Inpatient Sample), yielding impressively large numbers that add to its validity. Such valuable information provides an important resource for authors, granting agencies, funding agencies, and policy makers. The burden of disease is clearly illustrated in tables and in the comments within the text.PubMedCrossRefGoogle Scholar

Over the 10-year period studied from statistics collected by the National Health Service in England (excluding private patients), there was an increased admission for cholelithiasis. The frequency of cholecystectomy actually declined with an increase in therapeutic endoscopic procedures.PubMedCrossRefGoogle Scholar

American Indians have the highest prevalence of gallstones in the world: approximately 50% of men and 80% of women. This rather large ultrasound study involved 3296 middle-aged (47 years+) American Indians whose racial origin was based on their grandparents’ heritage; 64.1% of the women and 29.5% of the men had gallbladder disease (as gallstones or previous cholecystectomy). The epidemic proportions were no different across 13 tribes in three different states.PubMedCrossRefGoogle Scholar
