Rigid esophagoscopy has been used by otolaryngologists for evaluation of the esophagus for over 100 years. Few studies have examined the diagnostic accuracy of rigid esophagoscopy in patients with carcinoma of the head and neck. The goal of our study was to compare the diagnostic accuracy, complication rate, and costs of rigid esophagoscopy and flexible fiber-optic endoscopy in the evaluation of the esophagus in patients with head and neck carcinoma. We retrospectively reviewed the records of 195 patients with head and neck carcinoma who underwent both rigid esophagoscopy and flexible fiber-optic endoscopy within a 6-month period. We discovered 10 cases with discordant findings, of which 5 (50%) were esophageal carcinoma. The estimated cost was less for flexible endoscopy. No complications were reported in either procedure. Our study suggests that flexible fiber-optic endoscopy should replace rigid esophagoscopy in the evaluation of the esophagus in patients with head and neck carcinoma.
100多年来，耳鼻喉科医生一直使用硬式食管镜来评估食管。很少有研究探讨硬式食管镜在头颈部癌患者中的诊断准确性。我们研究的目的是比较硬式食管镜和可弯曲纤维内镜在评估头颈部癌患者食管时的诊断准确性、并发症发生率和成本。我们回顾性分析了195名头颈部癌患者在6个月内同时接受硬式食管镜和可弯曲纤维内镜检查的记录。我们发现10例检查结果不一致的病例，其中5例（50%）为食管癌。可弯曲内镜估计成本更低。两种检查方法均未报告并发症。我们的研究表明，在评估头颈部癌患者的食管时，可弯曲纤维内镜应取代硬式食管镜。
