About this study

Official title: Comparison of Multibending and Conventional Ultra-slim Upper Endoscope for the Direct Advance Into the Bile Duct Without Assisting Accessory in Peroral Cholangioscopy

The aim of this study is to evaluate the usefulness of a newly developed multibending ultra-slim upper endoscope for the successful direct peroral cholangioscopy (POC) without assisting accessory in comparison with conventional ultra-slim endoscope. The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.

Read the detailed description

Direct POC using an ultra-slim upper endoscope permits various diagnostic and/or therapeutic intraductal interventions under direct endoscopic visualization in selected patients who has dilated distal CBD and widened papillary orifice. Because the bile duct has anatomical position in acute angle with the duodenum, assisting accessories such as intraductal anchoring balloon, guidewire or overtube is usually required for the successful direct POC. Recently, direct peroral cholangioscopes have been developed for free-hand direct advancement of the endoscope into the bile duct from duodenum. Multibending ultra-slim endoscope may be expected to facilitate the advance into the bile duct by overcoming the acute angle between the bile duct and the duodenum. After randomization of enrolled patients into two groups, direct POC will be performed by using a conventional slim endoscope in control group and by using a multibending endoscope in study group.

What is being measured

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

  1. Technical success of the direct peroral cholangioscopy

    Successful insertion of a slim endoscope into the bile duct in no assisting accessories.

    Measured: 6 months

Secondary outcomes (1)
  1. Adverse events associated with direct POC

    1. Cholangitis: fever and abdominal pain with abnormal liver function test
    2. Hemobilia: bleeding from the bile duct
    3. Pancreatitis: abdominal pain with elevation of the serum amylase and lipase
    4. Bile duct perforation: any evidence of bile duct perforation in imaging studies.
    5. Air embolism: clinical and imagine findings with air embolism

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing ultra-slim upper endoscope in people with Common Bile Duct Calculi and Biliary Tract Cancer, run by Soonchunhyang University Hospital 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 6 inclusion and 7 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 3 Nov 2015. 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?

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?

Technical success of the direct peroral cholangioscopy (time frame: 6 months). 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 NCT02189421, 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 3 Nov 2015.
