What this trial studies

This multicenter cohort study aims to continuously enroll patients with biliary dilatation from 25 medical centers across China. It will collect comprehensive data on demographics, clinical characteristics, and long-term outcomes to establish a national cohort for bile duct dilatation. The study seeks to clarify the epidemiological and pathological features of the condition, assess cancer risks, and determine optimal surgical intervention timing. Additionally, it will compare perioperative risks and quality of life among different patient types following surgical treatment.
