BACKGROUND AND AIMS: The knowledge of natural history is essential for disease management. We evaluated the natural history (e.g. frequency and characteristics of symptoms and clinical outcome) of gallstones (GS) in a population-based cohortstudy. METHODS: A total of 11 229 subjects (6610 men, 4619 women, age-range: 29-69 years, mean age: 48 years) were studied. At ultrasonography, GS were present in 856 subjects (338 men, 455 women) (7.1%). GS were followed by means ofa questionnaire inquiring about the characteristics of specific biliary symptoms. RESULTS: At enrollment, 580 (73.1%) patients were asymptomatic, 94 (11.8%) had mild symptoms and 119 (15.1%) had severe symptoms. GS patients were followed upfor a mean period of 8.7 years; 63 subjects (7.3%) were lost to follow up. At the end of the follow up, of the asymptomatic subjects, 453 (78.1%) remained asymptomatic; 61 (10.5%) developed mild symptoms and 66 (11.4%) developed severe symptoms. In subjects with mild symptoms, the symptoms disappeared in 55 (58.5%), became severe in 23 (24.5%), remained stable in 16 (17%); in subjects with severesymptoms, the symptoms disappeared in 62 (52.1%), became mild in 20 (16.8%) and remained stable in 37 (31.1%). A total of 189 cholecystectomies were performed: 41.3% on asymptomatic patients, 17.4% on patients with mild symptoms and 41.3% onpatients with severe symptoms. CONCLUSIONS: This study indicates that: (i) asymptomatic and symptomatic GS patients have a benign natural history; (ii) the majority of GS patients with severe or mild symptoms will no longer experience biliary pain; and (iii) a significant proportion of cholecystectomies areperformed in asymptomatic patients. Expectant management still represents a valid therapeutic approach in the majority of patients.

Abstract

BACKGROUND AND AIMS: The knowledge of natural history is essential for disease management. We evaluated the natural history (e.g. frequency and characteristics of symptoms and clinical outcome) of gallstones (GS) in a population-based cohortstudy. METHODS: A total of 11 229 subjects (6610 men, 4619 women, age-range: 29-69 years, mean age: 48 years) were studied. At ultrasonography, GS were present in 856 subjects (338 men, 455 women) (7.1%). GS were followed by means ofa questionnaire inquiring about the characteristics of specific biliary symptoms. RESULTS: At enrollment, 580 (73.1%) patients were asymptomatic, 94 (11.8%) had mild symptoms and 119 (15.1%) had severe symptoms. GS patients were followed upfor a mean period of 8.7 years; 63 subjects (7.3%) were lost to follow up. At the end of the follow up, of the asymptomatic subjects, 453 (78.1%) remained asymptomatic; 61 (10.5%) developed mild symptoms and 66 (11.4%) developed severe symptoms. In subjects with mild symptoms, the symptoms disappeared in 55 (58.5%), became severe in 23 (24.5%), remained stable in 16 (17%); in subjects with severesymptoms, the symptoms disappeared in 62 (52.1%), became mild in 20 (16.8%) and remained stable in 37 (31.1%). A total of 189 cholecystectomies were performed: 41.3% on asymptomatic patients, 17.4% on patients with mild symptoms and 41.3% onpatients with severe symptoms. CONCLUSIONS: This study indicates that: (i) asymptomatic and symptomatic GS patients have a benign natural history; (ii) the majority of GS patients with severe or mild symptoms will no longer experience biliary pain; and (iii) a significant proportion of cholecystectomies areperformed in asymptomatic patients. Expectant management still represents a valid therapeutic approach in the majority of patients.
