Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older presenting with symptoms of esophageal food bolus or foreign body.

Probably not a fit

Patients with prior esophageal surgery, head/neck cancer, or those who are clinically unstable may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will assess adult patients at WellSpan York Hospital Emergency Department who show signs of esophageal food or foreign body impaction. Trained emergency physicians will perform point of care ultrasound (POCUS) to visualize the presence of food bolus or foreign body and measure esophageal dilation. A control group of asymptomatic individuals will also be enrolled to establish baseline esophageal measurements. Patients will receive standard medical treatment, and their outcomes will be monitored over one month.

Why it matters

Potential benefit: If successful, this study could improve the diagnosis and management of esophageal obstructions, leading to better patient outcomes.

How similar studies have gone: While the use of point of care ultrasound in emergency settings is gaining traction, this specific application for esophageal food bolus detection is relatively novel.
