High amplitude, peristaltic esophageal contractions associated with chest pain and/or dysphagia.

Abstract

Esophageal manometric tracings obtained using low-compliance pneumohydraulic infusion systems were reviewed from patients with symptoms of chest pain and/or dysphagia. Using this sytem, we report on 7 symptomatic patients with markedly increased esophageal peristaltic amplitude. Maximal peristaltic amplitude for these 7 patients (225-430 mmHg) was greater than for normals (75-175 mmHg). Mean peristaltic amplitude for the 7 was 170 mmHg, which was greater than for normals (81 +/- 30 mmHg, mean +/- 2 SD). This finding is believed to reflect the sensitivity of currently available manometric systems. It may be possible with these techniques to define more clearly the bulk of presumed esophageal dysfunction, which is at present poorly characterized. The relationship of clinical symptoms to abnormal esophageal motility is often less than optimal and may result from an inability to define "normal" or from inadequacies of currently available techniques. Our observations of a subset of symptomatic patients having peristaltic contractions with amplitudes exceeding the normal range seem to characterize one form of esophageal motility defect. This abnormality was seen more frequently than diffuse esophageal spasm in our laboratory.
