Esophageal ring evaluation is best accomplished by which diagnostic study?

• A. Barium swallow
• B. Esophageal manometry
• C. Gastroesophageal endoscopy
• D. CT scan of the chest

Answer: (C)

Direct visualization of the esophagus with endoscopy is the best way to evaluate an esophageal ring because it lets you see the mucosal lesion itself, determine its exact size and location, assess surrounding mucosa for inflammation or other pathology, obtain biopsies if needed, and even treat the ring by dilation in the same procedure. While a barium swallow can suggest a ring by showing a smooth narrowing, it cannot confirm tissue characteristics or provide immediate therapy. Esophageal manometry focuses on motility rather than fixed anatomic lesions, and CT scans have limited sensitivity for mucosal rings and expose the patient to radiation. Endoscopy thus provides definitive visualization and the option for immediate management, making it the preferred diagnostic study.
