Detailed Description
Background: Pre-operative biliary drainage is advised to treat obstructive jaundice and optimize the clinical condition of patients with presumed resectable perihilar cholangiocarcinoma who are expected to be eligible for major liver resection. However, stent related complications such as cholangitis (37%) and stent dysfunction (19%) occur frequently. Creating the need for numerous re-interventions, re-admissions, delay of diagnostic work-up and potential surgery. Biliary drainage could be optimized by the use of a navel design short fully covered self-expanding metal stent (FCSEMS) which is currently examined in the CHORDA-pilot study. However, FCSEMS placement is not feasible in an considerable number of cases, in these patients the use of a plastic stent with a retrieval string could be beneficial over standard plastic stent placement, which makes removal possible although the stent does not reach into the duodenum.
Objective: To explore feasibility and efficacy of endoscopic drainage of patients with presumed perihilar cholangiocarcinoma eligible for major liver resection using a plastic stent with a retrieval string.
Study population: Patients with presumed perihilar cholangiocarcinoma that are judged eligible for major liver resection and require endoscopic biliary drainage of the future liver remnant.
lntervention: Endoscopic drainage of the future liver remnant using a plastic biliary stent with retrieval string (diameter 7 or 1 0Fr).
Primary outcome: Number of severe drainage related complications between inclusion and exploratory laparotomy. 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 comes first.
Secondary study parameters/outcome of the study (if applicable):
Secondary outcomes: technical and therapeutic success of biliary drainage, individual components of primary endpoints and quality of life.

Outcome Measures
Primary Outcome Measures
- Severe adverse events 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]
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.
Secondary Outcome Measures
- 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]
Number of patients who experience preoperative cholangitis.
- 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]
The number of drainage procedures required to achieve technical success.
- Therapeutic success of intervention within 14 days [14 days]
The number of patients who with therapeutic success, defined as normal caliber bile ducts in the future liver remnant on ultrasound examination and a decrease in total bilirubin concentration of at least 20% at day 7 relative to the concentration at baseline.
- 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]
The total number of drainage procedures that involved (attempted) stent (re-)placement.
- Bilirubin levels after 7 and 14 days [14 days]
Interval bilirubin decrease at 7 days and 14 days after biliary drainage relative to the bilirubin level at inclusion.
- Cancellation of surgery [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]
The number of patients with rescheduled or cancelled laparotomy due to severe drainage-related complications.
- Quality of life after 7 days. [7 days]
EORTC Quality of Life Questionnaire 30 (EORTC QLQ-30), the EORTC QLQ module for CCA and gallbladder cancer (EORTC QLQ-BIL21), and the EuroQol 5D (EQ-5D-5L). Scoring according to module, higher score means better outcome.
- Quality of life after 28 days. [28 days]
EORTC Quality of Life Questionnaire (EORTC QLQ-30 incl BIL-21 module and EQ-5D-5L). Scoring according to module, higher score means better outcome.
- Quality of life after 90 days. [90 days]
EORTC Quality of Life Questionnaire (EORTC QLQ-30 incl BIL-21 module and EQ-5D-5L). Scoring according to module, higher score means better outcome.
- Postoperative morbidity [30 days after surgery]
EORTC Quality of Life Questionnaire (EORTC QLQ-30 incl BIL-21 module and EQ-5D-5L). Scoring according to module, higher score means better outcome.
- Postoperative mortality [30 days after surgery]
Number of patients experiencing postoperative mortality
