【摘要】 目的探讨3种常见内镜对大肠癌异常隐窝灶的诊断结果.方法采用前瞻性研究方法筛选肠镜检查患者共600例,随机分组后分别采用常规内镜、染色内镜、窄带内镜进行肠镜检查,并进行病理检查,统计各组患者的检查结果和操作时长.结果染色内镜在发现率、判断准确率较其余两种方式高,具有统计学意义(P<0.05),并能在进展初期发现微小的异常隐窝灶,但操作时间较另外两组长,同样具有统计学意义(P<0.05).结论在异常隐窝灶诊断方面染色内镜具有显著优势,可为早期防治大肠癌提供良好的诊断基础.更多还原

【Abstract】 Objective To investigate the diagnosis results of aberrant crypt foci with three kinds of common endoscope in colorectal cancer.Method The prospective study was carried out to screen 600 cases diagnosed with enteroscopy.After they were randomly grouped,the conventional endoscope,chromoendoscope,and narrowband enteroscope were used to examine the pathological changes,and record the results and operation time.Results The discovery rate and accurate judgement rate in the group with chromoendoscope were higher than those in other two groups,and the difference between them has statistically significance(P < 0.05).In addition,tiny aberrant crypt foci could be found with chromoendoscope in the early stage,but the operation time was longer than that in other two groups and there is statistically significant(P < 0.05).Conclusion Chromoendoscopy should be significantly advantage in the diagnosis of aberrant crypt foci,which can provide a good basis for the early diagnosis of colorectal cancer.更多还原
