内镜窄带成像技术诊断早期胃癌及异型增生的价值分析

摘要

Objective:To investigate the diagnosis significance of narrow band imaging for early gastric cancer and dysplasia. Methods:We used the common gastroscope or staining and narrow band imaging for suspected lesions using indigo carmine staining,and combined with magnifying endoscopy for suspected lesions to observe,and did histopathologic examination at the same time.We compared and analyzed the information get on the 2 diagnostic methods.Results:The difference between the narrowband endoscopic imaging and endoscopic or staining endoscopy diagnosis effect was obvious,and there was statistical significance(P<0.05).The narrow band imaging in the observation of focal,superficial lesions clearly and more advantages;for the observation results of gastric pits and gastric mucosal microvascular show that the narrow band imaging accounted for a larger advantage.Conclusion:Narrow band imaging not only has the advantages of simple operation,safety,but also can be clearly found early gastric cancer or precancerous lesions of gastric cancer for early detection and timely taking measures of treatment of great significance.%目的：探讨内镜窄带成像技术对于早期胃癌和异型增生诊断的意义。方法：采用普通胃镜或染色检查与利用窄带成像技术对可疑病变区采用靛胭脂染色，再结合放大内镜对可疑病变进行观察，同时进行病理组织学检查，对2种诊断方法获得的信息进行对比分析。结果：内镜窄带成像与普通内镜或染色内镜诊断效果之间差异明显，且有统计学意义(P＜0.05)，在对局灶性、浅表性病变的观察方面窄带成像技术成像清晰而更具优势；对胃小凹形态和胃黏膜微血管观察的结果也表明内镜窄带成像技术占较大优势。结论：内镜窄带成像技术不仅操作简便、安全，而且能够清晰地发现早期胃癌或癌前病变，对于胃癌的早期发现、及时采取措施进行治疗意义重大。
