We determined whether an abbreviated motility study that is commonly employed in clinical esophageal manometrics was as accurate as an extended manometric evaluation in detecting abnormalities in the esophageal body. One hundred patients underwent both abbreviated (stationary catheter, 10 wet swallows) and extended manometries (stepwise catheter withdrawal, 62 +/- 1 wet swallows). Classification by the two techniques was identical in 83 patients. Abbreviated manometry failed to recognize nine abnormal motility patterns. The abbreviated method was least accurate in the identification of intermittent and focal motility abnormalities (sensitivity = 0.50). Misclassifications were related to catheter position and not solely to differences in the total number of swallows. Of the individual wave parameters measured by each method, detection of multipeaked contraction waves was the most discrepant (R = 0.59). These findings indicate that abbreviated esophageal manometry is reasonably well correlated with a more extended method in detecting esophageal motility disorders and, because of its relative simplicity, appears appropriate for use in clinical practice. Errors related to stationary recording port positions may interfere with the overall accuracy of the abbreviated technique.
