Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 50 adult patients with confirmed diagnosis of Crohn's disease and suspicion of perianal fistulae will be enrolled in the study. Number and length of fistulae will be evaluated through MRI and TPUS. In addition, the response to treatment, defined as rate of fistula closure will also be evaluated with both techniques

Who may be able to join

  • Patients >18 years
  • Confirmed diagnosis of Crohn's disease.
  • Clinical suspicion of perianal fistulae (e.g., perianal pain or swelling, drainage of pus, stool or stool from cutaneous fistula opening, and signs and symptoms of sepsis)

About this study

Crohn's disease (CD) is a life-long chronic inflammatory bowel disease (IBD) that may affect any site of the gastrointestinal tract, most frequently the ileum and colon. It is characterized by transmural inflammation and it can lead to strictures, due to activation of reparation of inflamed tissues and consequent fibrosis, or penetrating lesions, such as fistulas, between two different intestinal tracts or between intestine and surrounding organs. Fistula occurrence can lead to formation of abdominal or pelvic abscesses. Such complications cause intestinal damage and usually require surgery, leading to disability, impairment of patients' quality of life, with significant impact on direct and indirect health-care costs

Read the detailed description

The investigators aim to conduct a multicentric pilot prospective observational study on the accuracy of TPUS and MRI in the investigation of perianal fistulae in CD patients. Fifty adult patients with confirmed diagnosis of Crohn's disease and perianal fistulae will be enrolled by five international centres between June 2022 and June 2023.

According to the observational nature of the study, all the visits and procedures described below will be performed according to the diagnostic and therapeutic assignment required by clinical practice for the patients under study. TPUS and MRI are normally performed by clinical practice. The choice of treatment for the cure of the fistula (e.g. medical and / or surgical treatment) will be made by the referring physicians according to the international ECCO guidelines. Therefore, the choice of assigning the patient to the diagnostic and therapeutic procedures deemed most appropriate for each case is completely independent of the study.

Subjects will undergo both TPUS and pelvic MRI at baseline as for clinical practice. After radiological and ultrasound evaluation, subjects will be treated according to international ECCO guidelines. In particular, patients will undergo seton insertion and 2 weeks later they will start biologics at the discretion of the gastroenterologist in according with international guidelines . Surgical closure with the advancement flap (AF) or Ligation of the Intersphincteric Fistula Tract (LIFT) procedure will occur 8-12 weeks after seton placement, with seton removal during surgical closure. The choice of surgical technique will be at the discretion of the surgeon. Finally patients will undergo both TPUS and pelvic MRI after 12 months as for clinical practice.

TPUS findings will be compared with those of the standard MRI to assess perianal disease activity. For that purpose, the investigators will:

  1. Identify 50 CD patients with perianal fistulae. Those patients will undergo both standard pelvic MRI and TPUS.
  2. Treat all patients with perianal fistulae according to international guidelines (e.g., medical and/or surgical treatment).
  3. Monitor all patients included according to the scheduled follow-up to evaluate the value of TPUS findings in assessing perianal disease evolution.

Fistulae identified will be classified according to the MAGNIFI-CD Activity Index, a validated score ranging from 0 to 25. For both TPUS and MRI the positive value, indicating the presence of the fistula, is considered for a MAGNIFI-CD>6. It evaluates several items including the number of fistulas, length of fistulas, extension, presence of inflammatory mass, dominant features, and hyperintensity on post-contrast T1-weighted images. The investigators will calculate the MAGNIFI-CD also with the TPUS and they will evaluate if the results of the score obtained with the ultrasound are correlated to those obtained with the MRI.

  • A multicentric prospective observational longitudinal cohort study.Other

    Observational study on the accuracy of TPUS and MRI in the investigation of perianal fistulae in CD patients.

What is being measured

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

  1. Incidence rate of perianal fistulae through the MAGNIFI-CD index (by TPUS) and the standard MAGNIFI-CD index (by MRI)

    To compare the accuracy of the TPUS versus pelvic MRI in assessing perianal fistulae in CD patients. Accuracy is defined as the ability to identify perianal fistulae

    Measured: 1 year

Secondary outcomes (1)
  1. Rate of fistula closure, determined by the clinician, at 12 months.

    To compare the accuracy of the TPUS versus pelvic MRI in evaluating response to treatment in CD patients with fistulae

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Crohn Disease and Perianal Fistula, run by IRCCS San Raffaele at 1 site in Italy.

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 4 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 10 Feb 2023. 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 Italy. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact MARIANGELA ALLOCCA (0226432069, allocca.mariangela@hsr.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence rate of perianal fistulae through the MAGNIFI-CD index (by TPUS) and the standard MAGNIFI-CD index (by MRI) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Feb 2023.
