title: A case of inability to belch.
abstract: A 22-year-old man was unable to belch. He could sense intraesophageal gas, but had no chest pain. An upper gastrointestinal X-ray series and endoscopic examination showed no abnormalities. Esophageal manometry showed normal relaxation of both the upper and lower esophageal sphincters with primary peristalsis during deglutition. However, bolus injection of air into the middle esophagus failed to initiate the belch reflex.
