Trial summary

Malignant obstructive jaundice is a common complication of advanced stage cholangiocarcinoma, GB cancer, and pancreatic cancer. In biliary stricture by malignancy, biliary drainage with placement of self-expanding metal stent (SEMS) for palliation is the therapy of choice in these patients. Read more about this study

About this study

Official title: A Prospective Randomized Study for Efficacy of Side-by-side Compared to Stent-in-stent Technique in the Endoscopic Management of Malignant Hilar Biliary Obstruction

Malignant obstructive jaundice is a common complication of advanced stage cholangiocarcinoma, GB cancer, and pancreatic cancer. In biliary stricture by malignancy, biliary drainage with placement of self-expanding metal stent (SEMS) for palliation is the therapy of choice in these patients. On hilar biliary malignant obstruction, bilateral stent used to be inserted. There are two kinds of bilateral metal stent insertion methods in hilar biliary malignant obstruction. (Stent in stent vs. side by side) Previously, two studies was conducted to show the superiority of bilateral metal stent insertion between stent in stent and side by side. Biliary drainage and stent patency was a little superior in side by side than stent in stent. But, complication related with bilateral metal stent was increased in patients with side by side method. Another study showed that there was no significant difference between those bilateral stent insertion methods. The most important concern about side by side method is associated with portal vein thrombosis by bilateral stent diameter. Selection of proper stent insertion method in patients with hilar malignant biliary obstruction is still controversial.

The purpose of this study is to investigate the patency of stent and survival of patients in side by side method (6mm sized M type) compared to stent in stent method (10mm sized LCD type) in patient with hilar malignant biliary obstruction.

What participants receive

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

  • side by sideProcedure or surgery

    Stenting generally begins with selective guidewire cannulation into the left and right intrahepatic bile ducts. Self-expandable metallic stent(SEMS) deployment is the conventional method and parallel SEMS can be inserted. SEMS deployment can be performed serially or simultaneously.

  • stent in stentProcedure or surgery

    After first SEMS deployment, contralateral placement of a second SEMS through the mesh of the first deployed stent was done and it looks like a Y configuration.

What is being measured

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

  1. Median patency duration

    Median patency duration from stent insertion date to stent occlusion date or last follow up date if stent is patent

    Measured: 1 year after stent insertion

Secondary outcomes (2)
  1. Overall survival

    Measured: 1 year

  2. complication rate

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing side by side and stent in stent in people with Cholangiocarcinoma and Gallbladder Cancer, run by Yonsei 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 8 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: status not confirmed, as of the sponsor's last update on 28 Jan 2019. 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Median patency duration (time frame: 1 year after stent insertion). 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 NCT02659852, which also lists 2 linked publications.

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 28 Jan 2019.
