早期胃癌内镜诊断进展

Progress of Endoscopic Diagnosis in Early Gastric Cancer

胃癌是我国发病率和病死率较高的恶性肿瘤,其预后与肿瘤分期密切相关。早期胃癌预后好,病死率低。内镜检查是诊断及筛查早期胃癌简单有效的方法。目前,我国早期胃癌的诊断率低,而提高内镜下发现病灶的能力并精准活检是早期胃癌诊断的关键。随着色素内镜、电子染色内镜、超声内镜等内镜技术的不断兴起及逐步普及,早期胃癌的检出率有了明显的提高。了解各项内镜技术在早期胃癌中的应用,有助于临床医师全面、有效、合理地制订早期胃癌诊断方案。

Gastric cancer is a malignant tumor with high morbidity and mortality in China,the prognosis of which is closely related to tumor staging.Early gastric cancer has a good prognosis and low mortality.Endoscopy is still a simple and effective method for the diagnosis and screening of early gastric cancer.At present,the diagnosis rate of early gastric cancer in China is low.Improving the detection of lesions under endoscopy and accurate biopsy are the keys to improve the diagnosis of early gastric cancer.With the development of endoscopic techniques such as chromoendoscopy,electron staining endoscopy,and ultrasonic endoscopy,the detection rate of early gastric cancer has been significantly improved.Grasping the application of various endoscopic techniques is helpful for making comprehensive,effective and reasonable diagnostic plans for early gastric cancer.
