Can symptoms predict esophageal motor function or acid exposure in gastroesophageal reflux disease? A comparison of esophageal manometric and twenty-four-hour pH parameters in typical and extraesophageal gastroesophageal reflux disease. J Clin Gastroenterol
Optional Fields
It has been suggested that patterns of esophageal motor function and acid exposure may differ between those patients with gastroesophageal reflux disease (GERD) with classic symptoms and those with extraesophageal manifestations. Our objective was to compare various parameters of esophageal motility and acid exposure between groups of patients who had presented with extraesophageal manifestations of GERD alone, a combination of classic and extraesophageal manifestations, or classic GERD symptoms alone. A retrospective review of consecutive patients undergoing esophageal manometry and 24-hour dual-channel esophageal pH testing was performed. Information on patient demographics, symptoms, and results of various manometric and pH testing parameters was examined. We evaluated 84 patients: 32 with extraesophageal symptoms alone, 24 with both classic and extraesophageal symptoms, and 28 with classic symptoms alone. Apart from a trend toward less supine acid exposure in those with extraesophageal symptoms alone, no significant differences were evident among the three patient groups in any of the other parameters of proximal or distal esophageal acid reflux. With respect to motility parameters, lower esophageal sphincter pressure was lower in those with combined symptoms; otherwise, manometric findings were similar in the three patient groups. Our data do not support the hypothesis that the nature of the clinical presentation of GERD, whether in the form of classic or extraesophageal manifestations, is related to differing patterns of esophageal motor function or esophageal acid exposure.
