Trial summary

In Bismuth II-IV hilar cholangiocarcinoma patients with a predicted survival of longer than 3 months, metallic stent performance is superior to plastic stenting for palliation with respect to outcomes and cost-effectiveness. Read more about this study

About this study

Official title: Single Versus Multiple Deployment of Metallic Stents for Inoperable Malignant Hilar Biliary Obstruction: A Multicenter Prospective Randomized Study

In Bismuth II-IV hilar cholangiocarcinoma patients with a predicted survival of longer than 3 months, metallic stent performance is superior to plastic stenting for palliation with respect to outcomes and cost-effectiveness. However, the optimal stent type and the extent of drainage are issues that remain to be definitively decided. The optimal endoscopic management strategy is contentious. The investigators conduct the present study to prospectively in multi-centers compare unilateral (single) with bilateral (multiple) deployment in inoperable malignant biliary obstructions to clarify the clinical outcomes of these two deployment methods using metallic stents.

In Bismuth II-IV hilar cholangiocarcinoma patients with a predicted survival of longer than 3 months, metallic stent performance is superior to plastic stenting for palliation with respect to outcomes and cost-effectiveness.

However, the optimal stent type and the extent of drainage are issues that remain to be definitively decided. The optimal endoscopic management strategy is contentious.

The investigators conduct the present study to prospectively in multi-centers compare unilateral (single) with bilateral (multiple) deployment in inoperable malignant biliary obstructions to clarify the clinical outcomes of these two deployment methods using metallic stents.

First as an unilateral or bilateral stent will be deployed according to criteria.

In bilateral group, stent-in-stent or side-by-side deployment will be included.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Metallic stent deployment in hilar obstructionDevice

    Also called Single stent insertion, Multiple stent insertion using stent-in-stent method, Multiple stent insertion using side-by-side method

    Single stent insertion: metal stent deployment to right or left intrahepatic duct Multiple stenting: Stent-in-stent or side-by-side deployment

Multiple stent deploymentActive comparatorMetallic stent deployment in hilar obstruction. Insertion of multiple metallic stent to the dominant targeted duct such as right anterior (segments V and VIII), right posterior (segments VI and VII) or left (segments II-IV).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Reintervention rate when stents occluded

    When the stents occluded after successful single or multiple stent deployment, the outcome measure is assessed.

    Measured: 2 years

Secondary outcomes (1)
  1. Technical success of single or multiple stents

    When the bilirubin level decrease more than 50% within one week or 75% within one month.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A study testing Metallic stent deployment in hilar obstruction in people with Klatskin Tumor, run by Soon Chun Hyang University at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reintervention rate when stents occluded (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02166970, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2017; AzTrials last refreshed its copy on 2 Nov 2026.
