Study summary

Primary Objective: To document state-of- the-art multi-modality management of occluded biliary SEMS aiming to minimize number of reinterventions while providing symptom relief without procedure-related serious adverse events.

NOTE: This study will be hypothesis-generating for an anticipated randomized controlled study (RCT) to compare outcomes of placement of a plastic stent inside the occluded SEMS to outcomes of the proposed multi-modality approach.

Read the detailed description

Study Design:

Prospective, multi-center, single arm, post market, observational study

Two groups:

  • Sludge group: SEMS occluded due to sludge/stones in SEMS
  • Ingrowth/overgrowth group: SEMS occluded due to malignant tumor ingrowth or benign hyperplastic tissue overgrowth

Primary Endpoint:

Successful restoration of bile duct drainage with biliary obstructive symptom and cholangitis relief as applicable, without procedure related SAE'S, from procedure through 30 days of follow-up.

Secondary Endpoints:

  1. Occurrence and severity of procedure related serious adverse events from procedure through 30 days after procedure
  2. Resolution of cholangitis where applicable
  3. Technical success of procedure performed for restoration of bile duct drainage, overall and stratified by treatment group Sludge group: Ability to restore stent patency by cleaning the stent content followed by cholangiographically or cholangioscopically confirmed restored stent patency Ingrowth / overgrowth group: Ability to perform biliary radio frequency ablation (RFA) followed by cholangiographically or cholangioscopically confirmed restored stent patency
  4. Improvement of biliary obstructive symptoms at 1 week and 1 month post procedure compared to Baseline
  5. Improvement of Laboratory Liver Function Tests (LFT) at 1 week and 1 month post procedure compared to Baseline
  6. Biliary Reintervention rate from procedure through 30 days after procedure, including reinterventions caused by plastic stent occlusion
  7. Impact of cholangioscopy on current standard of care, which is to place a stent inside the occluded SEMS by

    • Avoiding placement of a second stent (plastic or metal)
    • Avoiding a repeat ERCP
    • Reducing associated cost

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

    1. Age 18 or older 2. Willing and able to comply with the study procedures and provide written to participate in the study 3. Recurrent biliary obstructive symptoms after biliary SEMS placement 4. Biliary SEMS occlusion.

Exclusion criteria

Exclusion Criteria:

    1. for endoscopic techniques 2. Ongoing cholangitis. NOTE: In case a patient presents who meets the inclusion and exclusion criteria, but has cholangitis, then a naso-biliary drain (NBD) will be placed before the ERCP until the cholangitis resolves.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Active comparator
    Sludge group

    If Single operator cholangioscopy reveals only sludge then sludge will be cleared using conventional technique during ERCP.

    Device: Single operator cholangioscopy, Endoscopic biliary RFA

  • Active comparator
    Ingrowth / Overgrowth

    If Single operator cholangioscopy reveals tumour ingrowth or overgrowth then to evaluate the role of biliary RFA for occluded stent due to tumour ingrowth or overgrowth

    Device: Single operator cholangioscopy, Endoscopic biliary RFA

Interventions

  • DeviceSingle operator cholangioscopy, Endoscopic biliary RFA

    Single operator cholangioscopy will be done to acess the cause of occluded SEMS, if tumour ingrowth or overgrowth seen then endoscopic biliary RFA will be done

    Also known as: SpyGlass cholangioscopy

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 28, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
