What researchers measure

Primary outcomes

  1. recurrence rate

    abdominal ultrasound or MRCP/CT was used to examine every 3 months after operation for 1 year, and the recurrence was recorded.

    Time frame: 1 year

Secondary outcomes

  1. improvement rate of liver function index

    5ml of fasting elbow venous blood was taken before treatment and 3 days, 1 week and 2 weeks after treatment respectively. The blood samples were centrifuged and the supernatant was taken. Total bilirubin (total bilirubin, TBil), glutamic pyruvic transaminase (Alanine aminotransferase, ALT), glutamic oxaloacetic transaminase (Aspartate aminotransferase, AST) and γ-glutamyl transpeptidase (γ-glutamyl transpeptidase, GGT)) in blood samples were detected by automatic biochemical analyzer.

    Time frame: 3 days, 1 week and 2 weeks
