Objective To discuss the diagnostic significance of the clinical, pathlological features and endoscopy in colorectal adenocarcinoma. Methods All 182 clinical cases diagnosed by endoscopy were analyzed retrospectively. Endoscopic signs and pathological basis were analyzed. Results Pathological diagnosis showed 118 cases of adenocarcinoma, 20 cases of mucinous adenocarcinoma, 15 cases of signet-ring cell carcinoma, 17 cases of squamous cell carcinoma, 6 cases of carcinoid tumors and 4 cases of polyps. Endoscopic diagnosis rate of colorectal adenocarcinoma was 100％. The sensitivity of the main signs of microscopic cancer for pathological diagnosis was 86.8％. Conclusion The typical signs of adenocarcinoma under endoscope have high sensitivity for colorectal adenocarcinoma.%目的 探讨大肠腺癌的临床、病理学特征及内镜对大肠腺癌的诊断意义.方法 回顾分析182例经内镜检查诊断为大肠腺癌的临床资料及其病理诊断结果,分析内镜征象的病理基础.结果 病理回报腺癌118例,黏液腺癌20例,印戒细胞癌15例,鳞癌17例,类癌6例,息肉6例.内镜对大肠腺癌诊断符合率为100%;镜下腺癌的主要征象对病理的诊断敏感性86.8%.结论 内镜下腺癌的典型性征象对大肠腺癌的诊断敏感性较高.
