Since the mid 1900s, esophagoscopy has been performed under sedation or general anesthesia. With transnasal esophagoscopy (TNE), there has been a return to awake, in-office esophagoscopy. Technologic advances have allowed the advent of a ultrathin, flexible esophagoscope that is introduced transnasally, allowing esophagoscopy to be performed in unsedated patients. TNE correlates with conventional esophagoscopy (sedated, flexible esophagoscopy) in diagnostic capacity. Over time, as the benefits of TNE have become elucidated, the procedure has gained wider acceptance and continues to have its role in patient care defined.
自20世纪中叶以来，食管镜检查一直是在镇静或全身麻醉下进行的。随着经鼻食管镜检查（TNE）的出现，又回归到了在门诊清醒状态下进行食管镜检查。技术的进步使得一种超薄、可弯曲的食管镜得以问世，这种食管镜可经鼻插入，从而能够在未使用镇静剂的患者中进行食管镜检查。TNE在诊断能力方面与传统食管镜检查（镇静、可弯曲食管镜检查）相当。随着时间的推移，TNE的优势逐渐显现，该检查方法已得到更广泛的认可，并且在患者护理中的作用也不断得到明确。
