Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 years old presenting to the emergency department with suspected SBO and low to moderate pretest clinical probability.

Probably not a fit

Patients who are under legal guardianship, pregnant, nursing, or have already had imaging confirming SBO will not benefit from this study.

What this trial studies

This observational study aims to evaluate the effectiveness of Point of Care Ultrasound (POCUS) in diagnosing Small Bowel Obstruction (SBO) in emergency department patients. Currently, diagnosis relies heavily on abdominal CT scans, which have drawbacks such as radiation exposure and increased costs. The study will assess the diagnostic accuracy of POCUS and its ability to rule out SBO, potentially improving patient management and reducing unnecessary CT scans. Additionally, it will explore the use of Gestalt probability assessments by physicians to evaluate the likelihood of SBO based on clinical presentation.

Why it matters

Potential benefit: If successful, this approach could reduce reliance on CT scans, minimizing radiation exposure and healthcare costs for patients with suspected SBO.

How similar studies have gone: Previous studies have shown promising results for POCUS in diagnosing SBO, indicating that this approach may be effective.
