Radiography and manometry are complementary investigations in the diagnosis of esophageal motility disorders. In most centers, however, manometry is not available and diagnosis is based on radiography alone.
To correlate the findings on radiography in patients with esophageal motility disorders in whom a manometric diagnosis was available.
Retrospective analysis of esophageal manometry and barium contrast studies of 138 patients, done for suspected motility disorders, over a period of two years.
Manometry was abnormal in 111 (80.4%) cases [achalasia 87, scleroderma 6, non specific esophageal motility disorders (NEMD) 13, diffuse esophageal spasm (DES) 5]. Radiology was abnormal in 106 cases; the overall radiographic sensitivity was 73.9% (achalasia 87.4%, scleroderma 83.3%, NEMD 38.5%) and the positive predictive value was 75.5% (achalasia 95%, scleroderma 100%, NEMD 29.4%).
Radiography has a high sensitivity and positive predictive value in esophageal motility disorders like achalasia and scleroderma but in DES and NEMD the two investigative modalities (radiography and manometry) do not correlate well.
放射学检查和测压法是诊断食管动力障碍的互补性检查方法。然而，在大多数医疗中心，无法进行测压法检查，诊断仅基于放射学检查。
将有测压法诊断结果的食管动力障碍患者的放射学检查结果进行对比。
对138例因疑似动力障碍在两年内进行食管测压和钡剂造影检查的患者进行回顾性分析。
111例（80.4%）患者测压结果异常[贲门失弛缓症87例，硬皮病6例，非特异性食管动力障碍（NEMD）13例，弥漫性食管痉挛（DES）5例]。106例患者放射学检查结果异常；放射学检查的总体敏感性为73.9%（贲门失弛缓症87.4%，硬皮病83.3%，NEMD 38.5%），阳性预测值为75.5%（贲门失弛缓症95%，硬皮病100%，NEMD 29.4%）。
放射学检查在贲门失弛缓症和硬皮病等食管动力障碍中具有较高的敏感性和阳性预测值，但在弥漫性食管痉挛和非特异性食管动力障碍中，这两种检查方法（放射学检查和测压法）的相关性不佳。
