电子喉镜在食管检查中的初步应用

目的 探讨电子喉镜在食管检查中的应用价值.方法 2009年6月至2011年6月在鼻腔表面麻醉下对50例患者应用电子喉镜进行食管检查,其中男32例,女18例；年龄16～88岁,平均53.8岁；慢性咽炎16例,单侧声带麻痹9例,吞咽不利6例,喉癌5例,下咽癌4例,慢性咳嗽和可疑食管异物各3例,颈部转移癌2例,喉接触性肉芽肿和颈部淋巴结肿大各1例.结果 经表面麻醉后,所有患者均能耐受并顺利完成检查,4例患者通过食管入口时出现轻微的恶心反应.食管镜检38例未见异常,发现食管霉菌病和食管炎各3例,食管异物和食管下端食物残留各2例,食管癌和食管划伤各1例,阳性发现率24％ (12/50).结论 电子喉镜可以兼顾经鼻电子食管镜或胃镜的一些功能,对食管病变的初筛诊断有一定意义.

Electronic laryngoscope for transnasal esophagal examination

Objective To evaluate the value of electronic laryngoscope for transnasalesophagoscopy.Methods The electronic laryngoscope was used for transnasal esophagoscopy in 50 patientsfrom June 2009 to June 2011.There were 32 males and 18 females with their age ranged from 16 -88 years (mean 53.8 years).Before esophagoscopy,1％ ephedrine-dicaine mixture was sprayed into the nasal and pharyngeal cavities for topical anesthesia.The esophagoscopy was used for screening examination in the patients with reflux,globus sensation,dysphagia,head and neck cancer,suspected foreign body,and vocal cord paralysis,etc.Results The transnasal esophagoscopy with electronic laryngoscope was performed successfully in all the patients.Mild nausea and vomiting occurred in 4 patients,but no patient required to stop the examination.Of the 50 patients,38 patients (76％) had normal findings and 12 patients (24％)had positive findings of the esophagus.Esophageal cancer was diagnosed in one patient,esophageal foreign body in 2 patients,esophageal injury in one patient,candidal esophagitis in 3 patients,esophagitis in 3 patients,and achalasia of the cardia in 2 patients.Conclusions The electronic laryngoscope for transnasal esophagoscopy is an alternative to conventional esophagoscopy,which is useful for screening the esophagus in the patients with reflux,globus,dysphagia,head and neck cancer,and suspected foreign body,etc.
