Abstract excerpt

BACKGROUND: Jackhammer Esophagus is defined as intact esophageal peristaltic contractions with extremely elevated amplitudes. We conducted a retrospective study to identify the frequency of esophageal hypercontractility and the clinical characteristics of Jackhammer Esophagus. METHODS: Charts for the patients referred for manometric study at a tertiary-care motility center were reviewed. Data were collected...
