Study summary

This study aims to evaluate the usefulness of disposable digital single-operator cholangioscopy (SOC) and intraductal ultrasound (IDUS) for the accurate diagnosis of indeterminate biliary stricture.

Read the detailed description

Although early and accurate diagnosis of cholangiocarcinoma from the biliary stricture is important, accurate differential diagnosis is still difficult even in computed tomography and magnetic resonance imaging. We planned to evaluate the usefulness of disposable digital single-operator cholangioscopy (SOC) and intraductal ultrasound (IDUS) for the accurate diagnosis of biliary stricture.

Study population

Patients with indeterminate nonicteric (Bilirubin \< 2mg/dL) biliary stricture

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. Patients aged 19 to under 80
  2. Presence of nonicteric biliary stricture
  3. Previous endoscopic sphincterotomy or papillary balloon dilatation

Exclusion criteria

Exclusion Criteria:

  1. Bleeding tendency ( > 1.5 or \< 50000 mm3)
  2. to ERCP
Terms in these criteria, in plain language(3)

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.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for May 2024; primary completion for Dec 2025, 19 months later.

Of 70 observational studies under Cholangiocarcinoma, half reached primary completion within 60 months of starting (the median), counting those still running; a quarter within 33. This study's planned 19 months is below that.

How these figures are worked out, and which studies are left out of them.

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 17, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
