Brief Summary

Congenital biliary dilatation necessitates timely intervention owing to potential complications. This study endeavors to enhance diagnostic precision using quantitative three-dimensional morphological characteristics. Objectives involve developing models to differentiate congenital from secondary biliary dilatation and identify intrahepatic involvement. Employing machine learning, robust diagnostic models aim to elevate clinical detection rates and improve accuracy.

Outcome Measures

Primary Outcomes (1)

  • Area under the Receiver Operating Characteristic curve (AUROC) of the diagnostic models for the differential diagnosis of congenital and secondary biliary dilatation and the identification of intrahepatic involvement

    The area under the ROC curve is calculated by integrating the ROC curve, which plots Sensitivity against 1 - Specificity.

    Pre-operation

Secondary Outcomes (4)

  • Area under the Precision-Recall curve (AUPRC) of the diagnostic models for the differential diagnosis of congenital and secondary biliary dilatation and the identification of intrahepatic involvement

    Pre-operation

  • Sensitivity of the diagnostic models for the differential diagnosis of congenital and secondary biliary dilatation and the identification of intrahepatic involvement

    Pre-operation

  • Specificity of the diagnostic models for the differential diagnosis of congenital and secondary biliary dilatation and the identification of intrahepatic involvement

    Pre-operation

  • Accuracy of the diagnostic models for the differential diagnosis of congenital and secondary biliary dilatation and the identification of intrahepatic involvement

    Pre-operation

Study Arms (2)

Congenital biliary dilatation

Patients with congenital biliary dilatation diagnosed according to the Japanese Study Group on Congenital Biliary Dilatation (JSCBD) guideline.

Other: Contrast-enhanced computed tomography (CECT) and 3D morphological analysis

Secondary biliary dilatation

Patients with secondary biliary dilatation attributed to choledocholithiasis or malignancies (hilar cholangiocarcinoma, pancreatic carcinoma, and distal cholangiocarcinoma).

Other: Contrast-enhanced computed tomography (CECT) and 3D morphological analysis

Interventions

Diagnosis models are established using quantitative morphological characteristics extracted from the 3D reconstructed bile duct from contrast-enhanced computed tomography (CECT) images.

Sampling MethodNon-Probability Sample
Study Population

Patients with congenital biliary dilatation diagnosed according to the Japanese Study Group on Congenital Biliary Dilatation (JSCBD) guideline or secondary bile duct dilatation due to choledocholithiasis or malignancies such as hilar cholangiocarcinoma, pancreatic carcinoma, and distal cholangiocarcinoma who underwent contrast-enhanced computed tomography (CECT) at Beijing Tsinghua Chang Gung Hospital from 2014 to 2022.

You may qualify if:

  • The patients with biliary dilation who underwent contrast-enhanced computed tomography (CECT) at Beijing Tsinghua Chang Gung Hospital from 2014 to 2022.

You may not qualify if:

  • Patients without pre-operative CECT scans or developing cholangiocarcinoma due to congenital biliary dilatation.
