Inter and intra-observer agreement in classifying the presence of gallstones by ultrasonographic images according to established criteria was studied. A film recording of 50 routine ultrasonographic examinations of the gallbladder was read by each of the 46 observers who participated in the Multicenter Italian Study on Epidemiology of Cholelithiasis (M.I.COL.). The overall Kappa score for inter-observer agreement was 0.649, while intra-observer agreement was "good" or "excellent" (Kappa scores greater than 0.60) in 75% of the observers. No statistical difference for inter-observer agreement between "novices" and "expert" echographers was found in the overall Kappa statistic or in category-specific Kappa scores (gallstone, no gallstone, doubtful and inconclusive examinations) The present study suggests that the development of explicit criteria by a group of trained echographers does not eliminate inter- and intra-observer disagreement in categorizing subjects for gallbladder stones.

The prevalence of gallstone disease (cholelithiasis and previous cholecystectomy for gallstones) in the population of the town of Sirmione, Italy, examined by ultrasonography, was 6.7% in men and 14.6% in women, ranging from 18 to 65 yr of age (overall prevalence = 11%). The prevalence of cholelithiasis in the same age span was 6.9% (4.5% in men and 8.9% in women). Prevalence of cholelithiasis increased with age in both sexes. Twenty-two percent of gallstone subjects suffered from biliary pain vs. 2% of subjects without gallstones. No difference was observed in the frequency of nonspecific symptoms between subjects with and without gallstones. Of the 132 gallstone subjects, 108 (82%) were not aware of having gallstones prior to the study. Prevalence of gallstone disease was found to be higher in obese and hypertriglyceridemic subjects and to increase with the number of pregnancies.
