Host-Microbe Interactions in Biliary Dilatation

This study is an observational cohort study aimed at continuously enrolling patients with biliary dilatation and healthy controls. It will collect bile duct tissue samples and clinical data from participants across all age groups to establish a comprehensive cohort for biliary dilatation research. Based on this cohort, the study seeks to investigate the molecular mechanisms underlying biliary dilatation development and progression, explore the role of host-microbiome interactions in disease processes, and identify biomarkers associated with complications and malignancy risk, to establish evidence-based strategies for improved diagnosis and treatment of biliary dilatation.

Efficacy and Safety of Surgical Treatment for Type IVa CBD

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.

Biliary Dilatation National Special Disease Cohort in China

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 bile duct dilatation. Based on this cohort, the study seeks to clarify the epidemiological characteristics, pathological features, standard classification, disease progression, cancer risk, and optimal timing for surgical intervention in patients with bile duct dilatation. Additionally, it will compare the perioperative risks, long-term outcomes, and quality of life among different types of patients (including Todani types I, IVa, and V) following surgical treatment, to establish standardized surgical treatment strategies for each type.

The Application of Digital Intelligent Diagnostic and Therapeutic Technology in Biliary Dilation Diagnosis

This research discusses the clinical application value of augmented reality navigation technology combined with three-dimensional visualization technology in improving surgical safety and promoting the development of precision surgery. This technology can reduce intraoperative vascular and bile duct injuries, effectively avoid serious postoperative complications, and reduce residual cysts.

Timing of Operation in Children With a Prenatal Diagnosis of Choledochal Cyst

In this prospective study, we tried to select the operation time according to the cyst size and evaluate the treatment effect.
