Study population

Any benignant or malignant ERC indication in naive papilla

Eligibility criteria

Main inclusion criteria for patient enrollment were: ability to provide an ; age >/=18 years; any benignant or malignant ERCP indication.

All subjects were excluded from the study:

  • Patients who have already undergone endoscopic sphincterotomy
  • Patients unable to express informed consent
  • Pregnant or breastfeeding women
  • Patients with anatomical post-surgical alterations of the upper gastrointestinal (GI) tract
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Microbial assessment in patients undergoing to ERC with naive papilla

    Coltural assessment of the bile samples obtained pre- and post-sphincterotomy during ERC in naive papilla.

    Time frame: July 2022 to 2023

Secondary outcomes

  1. MDR and sentinel germs detection

    Determine the presence and the prevalence of MDR organisms and sentinel germs in bile.

    Time frame: July 2022 to 2023

  2. differences in the microbial community before and after sphincterotomy.

    Evaluation of differences in the microbial community before and after sphincterotomy.

    Time frame: July 2022 to 2023

  3. Identify possible correlations between pre sphincterotomy positive biliary cultures, polymicrobial population and MDR organisms with several clinical features and with laboratory signs of acute cholangitis.

    Identify possible correlations between pre sphincterotomy positive biliary cultures, polymicrobial population and MDR organisms with several clinical features and with laboratory signs of acute cholangitis.

    Time frame: July 2022 to 2023

  4. Identify potential differences in the pre sphincterotomy biliary microbial community depending on type of jaundice (benign or malignant).

    Identify potential differences in the pre sphincterotomy biliary microbial community depending on type of jaundice (benign or malignant).

    Time frame: July 2022 to 2023

  5. Check the presence of a possible association between specific biliary bacterial strains and definite pancreaticobiliary disorders.

    Check the presence of a possible association between specific biliary bacterial strains and definite pancreaticobiliary disorders.

    Time frame: July 2022 to 2023

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 3, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
