| Popis: | Horizontal pressure bands on high-resolution esophageal manometry with impedance (HREMI) tracings are often seen and thought to be due to cardiovascular structures compressing the esophagus. The aim of this study was to determine the prevalence and location of vascular pressure bands on HREMI studies and correlate these pressure bands to bolus clearance. HREMI studies in supine and upright positions from patients and normal volunteers were reviewed. Pressure bands were defined as bands of horizontal pressure greater than the 20 mmHg isobaric contour. Each swallow was reviewed with impedance to determine if bolus transit was impaired by the band. 38.6% of 251 patients and 36.4% of 11 normal controls had a pressure band present. There were a greater number of bands in supine versus upright position (patients: 130 vs. 25, P |
