探讨无痛胃镜及普通胃镜下食管裂孔疝的内镜下表现的异同点，为临床诊断提供依据。

回顾性分析2016年1月～2016年11月，就诊于新疆维吾尔自治区人民医院消化科的200例明确诊断滑动型食管裂孔疝并行胃镜检查患者(普通胃镜80例，无痛胃镜120例)的病历资料，对比总结两种检查方法的镜下特征。

无痛胃镜与普通胃镜下食管裂孔疝的共同特征：齿状线上移、食管裂孔压迹至齿状线的距离增加、His角变钝变平、贲门口扩大松驰等；不同之处在于无痛胃镜下食管裂孔疝的特征镜像缺失，既胃黏膜突入食管腔。

无痛胃镜和普通胃镜均能准确诊断食管裂孔疝，通过掌握这两种方法不同的内镜下表现，胃镜初学者都能较为准确的诊断食管裂孔疝。

To explore the similarities and differences for endoscopic findings of esophageal hiatal hernia under painless gastroscope and common endoscopic, which provide the basis for clinical diagnosis.

Patients were selected in January 2016 to November 2016 in The XinJiang Uygur Autonomous Region People′s hospital of Gastroenterology Department which have a clear diagnosis of sliding esophageal hiatal hernia.A total of 200 patients were done gastroscopy, painless gastroscopy in 120 cases, ordinary gastroscopy in 80 cases, the endoscopic characteristics of the two methods were prospective studied and compared.

The common features of painless gastroscope and common gastroscope of esophageal hiatal hernia: dentate line shift、The distance from the pressure traces of the esophageal hiatus to the dentate line increases、His angle becomes flattened、cardia expansion and relaxation; The difference is that in the painless endoscopic esophageal hiatal hernia features mirror image missing: That is gastric mucosa into the esophageal cavity.

Both the painless gastroscope and the common gastroscope can accurately diagnose hiatal hernia, by grasping the two methods of different endoscopic performance, endoscopy beginnerscan accurately diagnose esophageal hiatal hernia.
