About this study

Official title: Safety and Efficacy of Extracorporeal Shock Wave Lithotripsy and Endoscopic Retrograde Cholangiopancreatography for Pancreatic Stones

To determine the types, incidence and risk factors of adverse events after pancreatic extracorporeal shock wave lithotripsy (P-ESWL) and endoscopic retrograde cholangiopancreatography (ERCP), define the grading criteria of adverse events after P-ESWL and ERCP, and analyze the efficacy of P-ESWL and ERCP, which will provide evidence-based medical evidence to guide physicians' clinical practice.

Read the detailed description

Currently, pancreatic extracorporeal shock wave lithotripsy (P-ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) has become the preferred treatment for pancreatic duct stones. Although some studies had confirmed the safety and efficacy of P-ESWL and ERCP, the sample size were small and the follow-up period were short. Therefore, investigators designed this study with a large sample and a long follow-up period to clarify the efficacy and safety of P-ESWL and ERCP, so as to guide clinical work, standardize the diagnosis and treatment process of adverse events.

What participants receive

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

  • pancreatic extracorporeal shock wave lithotripsyProcedure or surgery

    Pancreatic extracorporeal shock wave lithotripsy is based on the principle of shock wave energy. Whenever energy is abruptly released in an enclosed space, shock waves are generated and then cross to the surface of pancreatic duct stones to cause further fragmentation.

What is being measured

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

  1. the incidence of post-ESWL adverse events

    An adverse event of P-ESWL is classified as either a complication or a transient adverse event (TAE), depending on severity. Complications are recognized as adverse events needing specific medical intervention and prolonged hospitalization, while TAEs are defined as transient injuries caused by shock waves, which required no medical intervention and do not prolong hospitalization.

    Measured: 1 months

Secondary outcomes (2)
  1. the rate of pancreatic duct clearance

    Complete clearance: more than 90% clearance of stone volume; partial clearance: 50% to 90% clearance of stone volume; unsuccessful clearance: failure to fragment the stones to less than 3 mm diameter or less than 50% clearance of stone volume.

    Measured: 1 week

  2. Pain relief of patients after P-ESWL and ERCP

    The ratio of patients with complete pain relief (an Izbicki pain score was ≤ 10), partial relief (an Izbicki pain score > 10 with a decrease of > 50%) and no relief.

    Measured: more than 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Pancreatic Duct Stone, run by Changhai Hospital at 1 site 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 3 inclusion and 2 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 11 Jul 2024. 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 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?

the incidence of post-ESWL adverse events (time frame: 1 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 NCT05916547, 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 11 Jul 2024.
