图像增强内镜在食管胃结合部癌中的诊断价值和应用现状

The diagnostic value and clinical application status of image enhanced endoscopy in esophago-gastric junction carcinoma

随着幽门螺杆菌根除疗法的大规模应用,人群感染率下降使幽门螺杆菌相关胃癌发生率降低.换言之,幽门螺杆菌阴性胃癌的比例会大幅提升,而作为与幽门螺杆菌感染关系不密切的食管胃结合部癌同样会成为今后胃癌防治中的新焦点.图像增强内镜是近年迅速发展的一项内镜技术,在早期胃癌和食管癌的诊断中发挥重要作用.而此项技术对于食管胃结合部癌是否同样有价值,仍有较多未解决的问题.笔者拟从内镜医师的角度,重点阐述图像增强内镜在食管胃结合部癌中的诊断价值和应用现状.

With the large-scale application of Helicobacter pylori(Hp)eradication therapy,the decline in the infection rate of the population will lead to a decrease in the occurrence of Hp-related gastric cancer.In other words,the proportion of Hp-negative gastric cancer will also increase significantly,and esophago-gastric junction carcinoma,which is not closely related to Hp infection,will also become a new focus in the prevention and treatment of gastric cancer in the future.Image enhanced endoscopy is a type of endoscopic technique that has developed rapidly in recent years,and has played an important role in the diagnosis of early gastric cancer and esophageal cancer.However,there are still many unsolved questions about whether this technology is also valuable for esophago-gastric junction carcinoma.The authors intend to review the current progress of image enhanced endoscopy in diagnosis and treatment of esophago-gastric junction carcinoma from the perspective of endoscopists.
