About this study

The recurrent rate of CBDS in patients with recurrent CBDS is high. It was reported that up to 60% of patients had stone recurrence within two years after stone retrieval by ERCP. Although EPLBD is useful for for extraction of large CBDS with less operation time and mechanical lithotripsy.It is not known whether EPLBD could prevent the recurrence in patients with recurrent CBDS.Although Harada et al found that EPLBD might reduce the short-term recurrence of CBD stones in patients with previous ES. It is a retrospective study with a small sample size (n=94).

Here a prospective, randomized controlled study including two tertiary centers was designed. The aim of this study was to investigate whether EPLBD could reduce the recurrence rate in patients with recurrent CBDS.

What participants receive

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

  • endoscopic papillary large balloon dilationProcedure or surgery

    Also called EPLBD

    For the patients in EPLBD group, a CRE balloon (diameter 10, 11, 12, 13.5, 15 mm; Boston Scientific) was chosen according to the diameter of bile duct. It was placed across the papilla orifice and then gradually filled with diluted contrast. When the waist disappeared, the balloon was kept inflated for 120s. The stones were then retrieved by a basket or a retrieval balloon.Mechanical lithotripsy was used if necessary

What is being measured

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

  1. Recurrent rate of CBDS within two years after ERCP

    Within the two years after ERCP, CBDS was found again by CT, MRCP, ERCP or biliary surgery

    Measured: up to 2 years

Secondary outcomes (6)
  1. recurrent time

    Measured: up to 2 years

  2. success rate of stone extraction

    Measured: up to 2 years

  3. success rate of stone extraction in the initial attempt

    Measured: up to 2 years

  4. performance time of ERCP

    Measured: up to 2 years

  5. rate of mechanical lithotripsy

    Measured: up to 2 years

  6. post-ERCP complication

    Measured: up to 2 years

Questions about this trial

What is this clinical trial studying?

A study testing endoscopic papillary large balloon dilation in people with Endoscopic Papillary Large Balloon Dilation, run by Air Force Military Medical University, China at 2 sites in China.

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 9 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: finished, as of the sponsor's last update on 31 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Recurrent rate of CBDS within two years after ERCP (time frame: up to 2 years). 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 NCT02330601, which also lists 3 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 31 May 2023.
