title: [A case report of jackhammer esophagus].
abstract: A 39-year-old female patient was referred to our hospital with a suspected esophageal motility disorder following a 4-month history of hiccup and dysphagia. Her past medical and family histories were unremarkable. Prior investigation with upper gastrointestinal endoscopy and esophagography failed to demonstrate any obvious pathology. Therefore, high-resolution manometry was performed, which showed the following: an integrated relaxation pressure (IRP) of 11.5mmHg; a distal contractile integral (DCI) of 6543mmHg-s-cm; and, a highest DCI of 9289mmHg-s-cm. A diagnosis of jackhammer esophagus was, therefore, considered. We reported on the details of this case and reviewed the relevant literature.
