Factors predictive of the successful treatment of choledocholithiasis.

The variables identified in this study, when considered in conjunction with the results of previously published studies, can be used to guide the choice of therapeutic methods for patients with choledocholithiasis in the future, given the significant difference in outcomes between the two groups. In the future, a prospective study should be performed to determine whether the same factors are predictive of the success of other methods of treatment (surgical or percutaneous).
