[Cholelithiasis in the region of Cartagena: an approximation to its real incidence based on the study of its symptomatic group].

We have studied the frequency of cholelithiasis in a group of patients who complained of clinical symptoms of cholelithiasis and lived in the region of Cartagena. This group of patients accounts for 40% of all the patients suffering from cholelithiasis this would account for 0.5% of the whole population and 1% of the exposed population over 30 year-of-age. Our results suggest that the population living in the region of Cartagena has a low-risk for cholelithiasis.
