Outcome Measures

Primary Outcomes (1)

  • Severe adverse events between inclusion and exploratory laparotomy

    Number of severe drainage related complications between inclusion and exploratory laparotomy. Severe complications are defined as any complication leading to additional invasive interventions, (extended) hospitalization, or death.

    Between inclusion and surgery. In patients who will not undergo exploratory laparotomy, the number of drainage-related complications will be measured until 7 days after the decision to cancel exploratory laparotomy or 90 days after inclusion, whichever

Secondary Outcomes (11)

  • The separate incidence of preoperative cholangitis between inclusion and exploratory laparotomy

    Between inclusion and surgery. In patients who will not undergo exploratory laparotomy, the number of drainage-related complications will be measured until 7 days after the decision to cancel exploratory laparotomy or 90 days after inclusion, whichever

  • Technical success of intervention

    Between inclusion and surgery. In patients who will not undergo exploratory laparotomy, the number of drainage-related complications will be measured until 7 days after the decision to cancel exploratory laparotomy or 90 days after inclusion, whichever

  • Therapeutic success of intervention within 14 days

    14 days

  • Number of drainage procedures between inclusion and exploratory laparotomy

    Between inclusion and surgery. In patients who will not undergo exploratory laparotomy, the number of drainage-related complications will be measured until 7 days after the decision to cancel exploratory laparotomy or 90 days after inclusion, whichever

  • Bilirubin levels after 7 and 14 days

    14 days

  • +6 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years or older.
  • Capable of providing written and oral informed consent.
  • Presumed perihilar cholangiocarcinoma.
  • Biliary obstruction in the future liver remnant.
  • Drainage naïve patients: total bilirubin \>50 umol/L
  • Patients with previous endobiliary drainage procedures: persistently rising total bilirubin \>50 umol/L (i.e. no stent placed or insufficient draining stent) or persistent biliary dilatation in the future liver remnant on imaging (i.e. previous stent placed in contralateral side of the liver).

You may not qualify if:

  • Incompletely recovered from any side effects of previous biliary drainage procedures. Patients are required to be off antibiotic treatment for at least 5 days.
  • Any contra-indication for major liver surgery (e.g. ECOG/WHO score ≥3).
  • Technical contra-indications for endobiliary drainage (e.g. previous gastrojejunostomy).
  • Distance between stricture and sphincter less than 2 cm.
  • Refusal to provide informed consent.
