What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This pilot study tested a plastic stent with a retrieval string to drain bile in 40 people with resectable bile duct cancer. The goal was to see if the stent could safely reduce bile buildup before surgery. Researchers measured serious complications and how well the stent worked.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
plastic biliary stent with retrieval string
What this could lead to
If successful, this stent could provide a safer, simpler way to drain bile before surgery, potentially reducing complications.
What could go wrong
This is a small pilot study with only 40 participants, so results may not apply to everyone. The stent could still cause infections or other complications.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18 years or older. * Capable of providing written and oral informed consent. * Presumed perihilar cholangiocarcinoma. * Biliary obstruction in the future liver remnant. * Drainage naïve patients: total bilirubin \>50 umol/L * Patients with previous endobiliary drainage procedures: persistently rising total bilirubin \>50 umol/L (i.e. no stent placed or insufficient draining stent) or persistent biliary dilatation in the future liver remnant on imaging (i.e. previous stent placed in contralateral side of the liver). Exclusion Criteria: * Incompletely recovered from any side effects of previous biliary drainage procedures. Patients are required to be off antibiotic treatment for at least 5 days. * Any contra-indication for major liver surgery (e.g. ECOG/WHO score ≥3). * Technical contra-indications for endobiliary drainage (e.g. previous gastrojejunostomy). * Distance between stricture and sphincter less than 2 cm. * Refusal to provide informed consent.
