目的 :探讨大肠癌误诊的原因及预防措施。方法 :回顾性分析 1991年 1月至 1999年 6月 10 1例经手术治疗大肠癌的资料。结果 :性别、病变部位与误诊无关 (P >0 0 5 ) ,青年人大肠癌误诊率明显高于 30岁以上患者 (P <0 0 5 ) ,直肠癌与结肠癌的临床表现和所误诊的疾病有显著差异 (P <0 0 5 ) ,误诊降低了手术切除率和根治性切除率。误诊的主要原因是大肠癌缺乏特异性临床表现。患者缺乏有关大肠癌的知识(5 9 38% ) ,医生缺乏警惕性 (4 0 6 3 % )、尤其是常遗漏简便易行的直肠指诊。结论 :为降低大肠癌的误诊率 ,普及大肠癌的有关知识 ,重视直肠指诊的临床价值 ,适时进行纤维结肠镜检查 ,对高危人群定期检查 ,注意青年人的发病。
Objective: To investigate the causes and preventive measures of misdiagnosis of colorectal cancer. Methods: A retrospective analysis of 101 cases of colorectal cancer data from January 1991 to June 1999 was performed. Results: The misdiagnosis rate of colorectal cancer in young people was significantly higher than that in patients over 30 years old (P <0.05), and the clinical manifestations and misdiagnosis of rectal cancer and colon cancer The disease was significantly different (P <0 05), misdiagnosis reduced the rate of resection and radical resection. The main reason for misdiagnosis is the lack of specific clinical manifestations of colorectal cancer. Patients lacked knowledge of colorectal cancer (59, 38%) and physicians lacked vigilance (40%, 36%). In particular, omission of an easy-to-use digital rectal examination was frequently missed. Conclusion: In order to reduce the misdiagnosis rate of colorectal cancer, popularize the knowledge of colorectal cancer, attach importance to the clinical value of digital rectal examination, make timely colonoscopy, check the high-risk groups periodically and pay attention to the onset of young people.
