What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers compare two ways to drain blocked bile ducts when a standard ERCP procedure fails. Both use an endoscope and ultrasound to create a new channel between the liver and stomach. One method adds an extra stent that reaches across the blockage. The trial measures how often the blockage returns and how safe each approach is in 88 adults with malignant distal biliary obstruction.

What this could mean

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

Active substance
endoscopic ultrasound-guided hepaticogastrostomy, a procedure that creates a new internal bypass between the liver and stomach to drain blocked bile
What this could lead to
If the antegrade stent approach works better, doctors could offer patients with blocked bile ducts a drainage method that stays open longer and needs fewer repeat procedures.
What could go wrong
This is a small randomized trial of 88 people at one hospital, so results may not apply broadly. The procedure is technically demanding and carries risks of bleeding, infection, or stent blockage.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 88 people

The number the study aims to enrol. It can still change while the study runs.

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

Inclusion Criteria: * Patients aged 18 years or older with malignant distal biliary obstruction * Failed ERCP * The papilla is inaccessible owing to a surgically altered anatomy or gastric outlet obstruction Exclusion Criteria: * Patients younger than 18 years old * Cancer infiltration of the gastric/duodenal wall within the planned puncture route * Patients with uncorrectable coagulopathy * Patients with unmanageable ascites * Patients with serious comorbidities that prohibited endoscopic management * Patients with pregnancy * Patients who cannot or refuse to provide informed consent
