Chile Biliary Longitudinal Study (Chile BiLS)
Chile BiLS was designed to investigate what drives the development of gallstones within a population of women in Chile. Participants were women aged 50 to 74 years with an ultrasound-diagnosed diagnosis of gallstones recruited from Araucanía region, Cautín Province, and Molina County in South and Central Chile. At baseline, over 4,700 participants were included in the study. Participants were followed up every year for 6 years or until they underwent a cholecystectomy to remove their gallbladder. Participants are followed up routinely through linkage with the Chilean national death registry.
