结肠镜检查在大肠癌诊断中的应用研究

目的探讨结肠镜检查在大肠癌诊断中的应用价值。方法回顾性分析经结肠镜及活检病理诊断为大肠癌患者328例患者的临床资料,对其临床表现、年龄、部位、病理类型等进行分析。结果患者多表现为便血、腹痛、大便性状改变和腹部包块等;男女平均发病年龄差异无统计学意义(P0.05),各年龄段中以40岁以后检出率逐渐增多,60~69岁及70~79岁为高检出率年龄段;直肠是大肠癌最多发部位;结肠镜下表现为隆起型225例(68.6%)、溃疡型71例(21.6%)、浸润型32例(9.8%);病理类型以管状腺癌最多。结论结肠镜可以直观地观察到结直肠黏膜的病变状况,结合活检病理诊断,有助于确定肿瘤的类型、分期,对确诊并制定治疗方案有重要参考价值。

Study on the application of colonoscopy in the diagnosis of colon cancer

Objective To explore the application value of colonoscopy in the diagnosis of colon cancer. Methods Clinical data of 328 colon cancer patients diagnosed by colonoscopy and biopsy were analyzed retrospectively in terms of clinical manifestations, age, tumor location, and type of pathology. Results Bloody stool, abdominal pain, stool changes, and abdominal mass were detected in most of these patients. The average age of onset was of no significant difference between men and women （P 〉 0.05）. The detection rate gradually increased after 40-year-old, and 60 to 69 years and 70 to 79 years age groups had the highest detection rate. The rectum was the predilection sites of colorectal cancer. Colonoscopy showed 225 cases （68.6%） of elevated type, 71 cases （21.6%） of ulcer, and 32 cases （9.8%） of infiltrative type. The most common histological type was adenocarcinoma. Conclusion Colonoscopy can visually observe colorectal mueosal lesions situation. Furthermore, in combination with biopsy, it helps to determine tumor type and stage, thus having an important value in diagnosing and formulating treatment plan.
