For suspected esophageal perforation causing mediastinitis, which imaging study is commonly used to identify a leak?

• A. Barium esophagram
• B. Chest ultrasound
• C. Plain abdominal X-ray
• D. Echocardiogram

Answer: (A)

When screening for a suspected esophageal perforation with mediastinitis, the test that best reveals a leak is a contrast esophagram that shows extraluminal contrast escaping from the esophagus. A barium esophagram is especially useful because it provides excellent outline of the esophageal lumen and makes even small leaks stand out as contrast leaking into the mediastinum or surrounding tissues. This direct visualization of the leak is more sensitive for detecting perforation than other imaging methods like ultrasound, plain X-ray, or echocardiography, which mainly show indirect signs. In practice, clinicians often begin with a water-soluble contrast study to minimize potential inflammatory reactions if a leak is present; if that study is negative yet suspicion remains high, a follow-up with barium improves leak detection.
