Outcome Measures

Primary Outcomes (2)

  • The occurrence of cholangitis

    Cholangitis that occurred within 1 month after endoscopic retrograde cholangiopancreatography(ERCP).

    1 month

  • Clinical success

    Clinical success was defined that the decrease in the total bilirubin level to less than 50% of the pretreatment value within 1 week or to less than 75% within 1 month.

    1 month

Secondary Outcomes (2)

  • Re-intervention

    6 month

  • Adverse events

    1 month

Study Arms (2)

Nasobiliary duct cutting

EXPERIMENTAL

Endoscopic retrograde cholangiopancreatography and endoscopic nasobiliary duct placement and drainage are conducted first. Upon achieving a postoperative state marked by satisfactory nasobiliary duct drainage and overall patient stability, the procedure entails the employment of endoscopic scissors. The tools are applied to make an incision on the external segment of the nasobiliary duct, positioned beyond the aperture of the primary duodenal papilla. Then, extracting the severed nasobiliary duct and retaining the portion inside it.

Device: Endoscopic nasobiliary duct cutting

Bilateral plastic stent

ACTIVE COMPARATOR

Standard protocol for the placement of bilateral biliary plastic stents in the management of malignant hilar biliary tract stenosis

Device: Bilateral plastic stent
