This study is a multicenter, bidirectional cohort study aimed at continuously enrolling patients with biliary dilatation from 25 medical centers in China. It will collect comprehensive life-cycle data from the cohort to establish a Chinese cohort for IVa biliary dilatation (BD). Based on this cohort, the study seeks to compare the perioperative risks, long-term outcomes, and quality of life of type IVa BD following surgical treatment, to establish standardized surgical treatment strategies for type IVa BD.
