To assess feasibility of unsedated esophagoscopy using a small-caliber disposable transnasal esophagoscopy and to compare its accuracy with standard endoscopy.
We prospectively included subjects who were referred for upper endoscopy. All subjects underwent transnasal endoscopy with E.G. Scan™. The disposable probe has a 3.6 mm gauge and at its distal end there is a 6 mm optical capsule, with a viewing angle of 125°. Patients underwent conventional endoscopy after the completion of E.G. Scan™. We describe the findings detected by the E.G. Scan™ and calculate the diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Kappa index for esophageal diagnosis.
A total of 96 patients (54 women), mean age of 50.12 years (14 to 79), were evaluated. In all cases we were able to perform esophagoscopy with E.G. Scan™. The average realization time was 5 min. A total of 58 alterations were detected in the esophagus, 49 gastric abnormalities and 13 duodenal abnormalities. We found that for esophageal varices, E.G. Scan™ has sensitivity, specificity and diagnostic accuracy of 95%, 97% and 97%, respectively. Kappa coefficients were 0.32 for hiatal hernia, 0.409 for erosive gastroesophageal reflux disease, 0.617 for Barrett's esophagus, and 0.909 for esophageal varices.
Esophagoscopy with E.G. Scan™ is a well-tolerated, fast and safe procedure. It has an appropriate diagnostic accuracy for esophageal varices when compared with conventional endoscopy.
评估使用小口径一次性经鼻食管镜进行非镇静食管镜检查的可行性，并将其准确性与标准内镜检查进行比较。
我们前瞻性纳入了因上消化道内镜检查而转诊的受试者。所有受试者均接受了带有E.G. Scan™的经鼻内镜检查。该一次性探头的口径为3.6毫米，其远端有一个6毫米的光学胶囊，视角为125°。患者在完成E.G. Scan™检查后接受传统内镜检查。我们描述了E.G. Scan™检测到的结果，并计算了食管诊断的诊断准确性、敏感性、特异性、阳性预测值、阴性预测值和Kappa指数。
共评估了96例患者（54例女性），平均年龄50.12岁（14至79岁）。在所有病例中，我们都能够使用E.G. Scan™进行食管镜检查。平均完成时间为5分钟。食管共检测到58处病变，胃异常49处，十二指肠异常13处。我们发现，对于食管静脉曲张，E.G. Scan™的敏感性、特异性和诊断准确性分别为95%、97%和97%。食管裂孔疝的Kappa系数为0.32，糜烂性胃食管反流病为0.409，巴雷特食管为0.617，食管静脉曲张为0.909。
使用E.G. Scan™进行食管镜检查是一种耐受性良好、快速且安全的操作。与传统内镜检查相比，它对食管静脉曲张具有适当的诊断准确性。
