Diffuse esophageal spasm: radiographic and manometric correlation.
Diffuse esophageal spasm (DES) is characterized by substernal chest pain, dysphagia, and a manometric pattern of frequent simultaneous contractions with intermittently normal peristalsis. The authors correlated the radiographic and manometric findings in 17 patients with DES to better clarify the role of radiography in the evaluation of this uncommon motility disorder. Incomplete or absent primary peristalsis was observed on radiographs in 13 patients (76%), and mild to severe tertiary activity was seen in 12 patients (71%). The mean estimated thickness of the esophageal wall in patients with DES was 2.6 mm compared with 2.5 mm in an age-matched control group of 17 patients with normal esophageal manometric findings (P greater than .05). The authors conclude that most patients with DES show abnormal esophageal motility on radiographs, although the findings were nonspecific and required clinical and manometric correlation. Esophageal wall thickness was normal in patients with DES and appears to be an overemphasized sign in differentiating DES from other esophageal motility disorders.
