Esophageal dysphagia is a common symptom in adults. Fluoroscopic contrast studies, endoscopy, and esophageal manometry have been used in the diagnosis of esophageal dysphagia for many years. The diagnostic yield has been improved with new test protocols that highlight abnormal bolus transit in the esophagus and outflow obstruction, as well as new high‐definition and high‐resolution technical advances in equipment. Functional luminal impedance planimetry and the addition of impedance to high‐resolution esophageal manometry have also allowed the assessment of new parameters to better understand esophageal structure and function. In this concise review, we describe the role and utility of various diagnostic modalities in the assessment of patients with esophageal dysphagia.

食管吞咽困难诊断方法的更新

食管吞咽困难是成人的常见症状。多年来，荧光镜对比研究、内窥镜检查和食管测压法已被用于诊断食管吞咽困难。新的测试方案提高了诊断率，这些方案突出了食道和流出道阻塞中的异常团块传输，以及新的高清和高分辨率设备技术进步。功能性管腔阻抗平面测量法和将阻抗添加到高分辨率食管测压法也允许评估新参数以更好地了解食管结构和功能。在这篇简明的综述中，我们描述了各种诊断方式在评估食管吞咽困难患者中的作用和效用。
