染色内镜对于直肠癌早期诊断的临床意义

摘要

Objective:To explore the clinical significance of chromo endoscopy for early diagnosis of colorectal cancer.Method:138 cases were randomly divided into observation group(n=69) and control group(n=69).Control group was treated with conventional endoscopy,observation group was stained,indigo carmine dye staining method,two biopsies were taken 3-5 blocks sent histology.Observing and comparing the situation of two groups.Result:The detection of inflammatory lesions stained endoscopy in 33 cases,30 cases of intraepithelial neoplasia and early cancer 6 cases;Control group 61 cases of inflammatory lesions detected by conventional endoscopy,6 cases of intraepithelial neoplasia early cancer 2 cases;The detection rate of observation group was 52.17%,was significantly higher than control group(X2=26.159,P<0.05).Conclusion:Endoscopic dyeing operation is simple,inexpensive,high rate of early detection of colorectal cancer,worthy of clinical application.%目的：探讨染色内镜对于直肠癌早期诊断的临床意义。方法：将138例患者随机分为观察组(n=69)和对照组(n=69)。对照组采用常规内镜检查，观察组采用染色内镜检查，染色方法为靛胭脂染色，两组均取3~5块活检送组织学检查，观察并比较两组患者的检查情况。结果：观察组经染色内镜检查检出炎性病变33例，上皮内瘤变30例，早期癌变6例；对照组经常规内镜检查检出炎性病变61例，上皮内瘤变6例，早期癌变2例。观察组检出率为52.17%，显著高于对照组的11.59%(字2=26.159，P<0.05)。结论：染色内镜操作简单易行，价格低廉，结肠癌早期检出率高，值得在临床上推广应用。
