摘　　要：随着医学技术的不断进步,消化内镜作为一种高效率、低创伤的诊断工具,在早期胃癌的检测和诊断中扮演了举足轻重的角色。胃癌作为全球常见的消化系统恶性肿瘤之一,其早期诊断对提高患者的生存率至关重要。本研究集中分析消化内镜在早期胃癌诊断领域内的最新进展,涉及高分辨率内镜、显微内镜、内镜下超声(EUS)及窄带成像(NBI)技术等。调查了现阶段150名临床医生对这些新技术的应用认知,并通过对早期胃癌病例的分析,确立了消化内镜诊断的准确性和应用范围。本课题通过对不同技术的比较研究,阐释了各技术在精确诊断早期胃癌中的具体优势及其潜在局限。研究表明,尽管高分辨率内镜提供了更清晰的图像,而NBI技术改善了黏膜病变的视觉识别,显微内镜和内镜下超声则在定量分析肿瘤浸润深度方面具有不可替代的优势。在实证研究中,我们还发现,尽管这些技术显著提高了早期胃癌的诊断率,但在实际临床应用中还面临技术普及、医生培训及成本效益等方面的挑战。提供了关于不同胃癌早期分型和诊断准则的详细对比,挖掘了影响诊断效率和准确性的关键因素。基于研究结果,建议未来在内镜设备的研发上强调操作的便利性以及更高的图像分辨率,同时提出加强医生相关技术培训,以及建立标准化诊断流程。综上所述,该研究不仅扩展了现有的医学知识,也为临床实践中提供了有价值的参考,对早期胃癌的精确诊断及治疗规划贡献了重要的理论和实证支持。With the continuous advancement of medical technology, gastrointestinal endoscopy has played a pivotal role as a high-efficiency, low-invasiveness diagnostic tool in the detection and diagnosis of early gastric cancer. As one of the common malignant tumors of the digestive system worldwide, early diagnosis is crucial for improving the survival rates of patients. This study focuses on analyzing the latest advancements in the field of gastrointestinal endoscopy for the early diagnosis of gastric cancer, involving high-resolution endoscopy, confocal microendoscopy, endoscopic ultrasound (EUS), and narrow-band imaging (NBI) technologies. It surveys the current understanding and application of these new technologies among 150 clinical doctors and, through the analysis of early gastric cancer cases, establishes the diagnostic accuracy and application scope of gastrointestinal endoscopy. Through comparative studies on different technologies, the research elucidates the specific advantages and potential limitations of each technology in the accurate diagnosis of early gastric cancer. The study indicates that while high-resolution endoscopy provides clearer images, and NBI technology improves the visual recognition of mucosal lesions, confocal microendoscopy and EUS are irreplaceable in their advantages for quantitatively analyzing tumor invasion depth. In empirical research, we also found that, although these technologies significantly improve the diagnostic rate of early gastric cancer, they still face challenges in clinical application regarding technology popularization, doctor training, and cost-effectiveness. Detailed comparisons between the different early gastric cancer typologies and diagnostic criteria were provided, identifying key factors affecting diagnostic efficiency and accuracy. Based on the research findings, it is suggested that future development in endoscopic equipment should emphasize ease of operation and higher image resolution, along with recommendations for enhanced doctor training in related tec
