What this trial studies

This study evaluates the effectiveness of small intestinal contrast ultrasound (SICUS) compared to traditional imaging methods like computed tomography enteroclysis (CTE) and magnetic resonance enterography (MRE) in patients with Crohn's disease. Participants will ingest polyethylene glycol to enhance imaging without radiation exposure, while also undergoing CTE for comparison. The study aims to determine the accuracy and patient comfort of SICUS in monitoring disease status and treatment response. Experienced operators will conduct all imaging procedures to ensure consistency and reliability of results.

Who should consider this trial

Good fit: Ideal candidates include patients with known small bowel Crohn's disease who require monitoring due to therapy assessment or new symptoms.

Not a fit: Patients who are obese with poor ultrasound windows, pregnant or lactating, or those with renal insufficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer, radiation-free imaging option for patients with Crohn's disease.

How similar studies have performed: While traditional imaging methods have been well-studied, the use of SICUS as a primary monitoring tool in Crohn's disease is relatively novel and less explored.

Eligibility criteria

Inclusion Criteria:

* Patients with known small bowel CD beyond reach of standard endoscopy who warrants monitoring of disease status either due to assessment of response to therapy/relapse/new unexplained symptoms, persistent disease activity, prior to switching therapy or deciding on surgical management.

Exclusion Criteria:

* Obese patients with poor ultrasound window
* pregnant/lactating mother
* Not willing for CT or enteroclysis examination
* Renal insufficiency precluding CT
