About this study

Official title: Proposal of Difficult Cannulation Criteria in Trainee Involved ERCP Cannulation Procedure

Endoscopic Retrograde Cholangiopancreatography (ERCP) is one of the most technically challenging procedures in gastrointestinal endoscopy. Selective deep cannulation is a critical step for the performance of ERCP. The incidence of difficult cannulation has been reported in many studies, ranging from 10% to 40% in patients with native papilla. Difficult cannulation is an independent risk factor for post-ERCP pancreatitis (PEP).

The definition of difficult cannulation has been proposed by European Society of Gastrointestinal Endoscopy (ESGE) guidelines. Initial cannulation is considered difficult with the presence of one or more of the following: more than 5 min for attempting to cannulate; more than 5 contacts with the papilla; more than 1 unintended pancreatic duct cannulation or opacification. The clear definition of difficult cannulation is important for making decisions during or after ERCP, including determining the appropriate time to transfer to advanced cannulation techniques (e.g. early precut) and whether prophylactic methods should be administrated to reduce the risk of PEP. Although 5-5-1 criteria have been widely used during ERCP practice or in relevant studies, it remains unclear whether the current criteria are suitable for the cannulation procedure with trainee involvement. Because of inexperienced manipulation of the scope and accessories, the involvement of trainees generally increases the overall cannulation time and attempts, which are the two important parameters in the criteria of difficult cannulation. Thus, the investigators hypothesized that the definition of difficult cannulation in trainee-involved cannulation might be different from the traditional 5-5-1 criteria.

What is being measured

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

  1. rates of difficult cannulation

    The proportion of the participants with cannulation-related parameters (cannulation time, cannulation attempts, or inadvertent PD cannulation) above the 75% percentile

    Measured: 2 hours

Secondary outcomes (3)
  1. incidences of PEP

    Measured: 48 hours

  2. overall adverse events

    Measured: 48 hours

  3. the proportion of advanced cannulation methods

    Measured: 4 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Biliary Cannulation and Endoscopic Retrograde Cholangiopancreatography, run by Air Force Military Medical University, China 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 1 inclusion and 1 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 30 Oct 2020. 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?

rates of difficult cannulation (time frame: 2 hours). 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 NCT04609917, 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 30 Oct 2020.
