【摘要】 目的探讨乙状结肠镜检查对大肠肿瘤的漏诊情况。方法总结分析惠州市中心人民医院(2006年～2008年)和广州南方医院(2004年～2006年)行结肠镜检查发现大肠肿瘤者、年龄为50～79岁的连续性资料。结果72.0%近端大肠肿瘤患者在其远端大肠未发现相应肿瘤性病变,其中男性该比例为66.5%,女性为82.3%;50～59岁、60～69岁、70～79岁年龄段的比例分别为74.7%、72.0%、67.9%。远近端大肠高级别癌灶比例分别为5.1%和15.8%(P<0.01)。结论近端大肠癌的恶性程度较远端大肠癌高;如果乙状结肠镜发现远端大肠肿瘤才进行全结肠镜检查,将导致72.0%近端大肠肿瘤漏诊。更多还原

【Abstract】 Objective To investigate the missed diagnosis of colorectal neoplasm by flexible sigmoidoscopy.Methods The subjects with colorectal neoplasm who subsequently underwent full colonoscopy,aged 50～79 years in Huizhou Municipal Central Hospital in 2006～2008 and in Guangzhou Nanfang Hospital in 2004～2006 were analyzed.Results The patients without distal colorectal neoplasms in the patients with proximal colorectal neoplasms were 72.0%,which were 66.5% in men and 82.3% in women,and which were 74.7% in 50～59 years old,72.0% in 60～69 years old and 67.9%in 70～79 years old.The percentage of distal colorectal cancer with high-grade in distal colorectal cancer and proximal colorectal cancer with high-grade in proximal colorectal cancer were 5.1% and 15.8% (P<0.01).Conclusion Malignant degree of proximal colorectal cancer is higher than distal.If we use flexible sigmoidoscopy to screen colorectal neoplasm,omisssion diagnosis rate is 72.0%.更多还原
