目的：回顾性分析38例结直肠癌的误诊原因,以期进一步提高早期诊断率。方法：我院1998年1月～2008年12月共确诊结直肠癌82例,误诊38例。误诊时间最短4.5个月,最长21.0个月,平均9.6个月。结果：本组误诊率为46.34%（38/82）,易误诊为痔疮、肠炎及急、慢性痢疾。结论：对有肠道症状的患者,按良性疾病治疗效果不佳时,应想到结直肠癌的可能,及时行结肠镜检查及肛门指诊检查,可降低结直肠癌的误诊率。

Clinical analysis of misdiagnosis reasons in 38 cases of misdiagnosed colorectal cancer

Objective：To retrospectively analyze the misdiagnosis reasons of 38 cases of colorectal cancer and increase the diagnosis rate in the early stage. Methods：From January 1998 to December 2008,a total of 82 cases were confirmed as colorectal cancer in our hospital,38 cases were misdiagnosed. Misdiagnosing time was between 4.5 months and 21.0 months,with an average time of 9.6 months. Results：The misdiagnosis rate in this group was 46.34% （38/82）. They were easily misdiagnosed as hemorrhoids,enteritis and colorectal polypus. Conclusion：There are some imperative measures to decrease misdiagnosis by examining colo endoscopy and anus-rectum finger check,when the patients who have diarrhoea have not effective results,we should consider the possibility of colorectal cancer.
