目前我国胃镜检查普遍使用白光内镜,致使早期胃癌(EGC)的诊断准确率低,易漏诊。图像增强放大内镜(M-IEE)通过增强病灶与周围黏膜的对比度提供更多有价值的信息,在消化道肿瘤的筛查和诊断上优势显著。放大窄带成像(M-NBI)和放大蓝激光成像(M-BLI)作为M-IEE的代表性技术,能够有效利用微血管和表面微结构分类系统提高EGC的诊断准确率,有助于EGC与胃萎缩、肠上皮化生、异型增生等癌前病变的鉴别诊断。采用M-IEE检测不仅可以识别高风险的胃部病变,而且可以减少对常规活检的依赖。将M-IEE与其他内镜及人工智能(AI)技术联用可进一步提高EGC的诊断准确率,具有良好的应用前景。

Currently, white light endoscopy is ordinarily used during the gastroscopy, which leads to the low accuracy rate of early gastric cancer (EGC) diagnosis, and the easily missing diagnosis.Magnifying image-enhanced endoscopy (M-IEE) mainly features the contrast between lesions and surrounding mucosa, and has unique advantages in the screening and diagnosis of gastrointestinal tumors.As representative image enhancement endoscopes, M-NBI and M-BLI can effectively use the VS classification system to improve the diagnosis accuracy rate of EGC, and help the differential diagnosis of EGC and precancerous lesions such as gastric atrophy, intestinal metaplasia, and dysplasia.In addition, the use of ME-IEE testing not only helps endoscopists identify high-risk gastric lesions, but also reduces the need for routine biopsies.The combination of M-IEE with other endoscopic and AI techniques can further improve the accuracy of diagnosing EGC, which has a good application prospect in the diagnosis of EGC.
