目的 对结肠镜检出的 2 83例大肠癌患者的临床、内镜及病理资料进行回顾性分析。方法 男15 6例 ,女 12 7例 ,平均年龄 5 7 6岁。就诊时主诉依次为血便、腹泻、腹痛及腹部包块。使用OlympusPCF - 2 0I、CF - 3 0I纤维结肠镜和OlympusCF - 13 0I电子结肠镜行全大肠检查。结果 检出直肠癌 13 7例 ( 4 8 4 % ) ,乙状结肠癌 4 8例 ( 17 0 % ) ,降结肠癌 2 4例 ( 8 5 % ) ,横结肠癌 4 2例 ( 14 8% ) ,升结肠癌 3 1例 ( 11 0 % ) ,回盲部癌 1例( 0 4 % )。组织学示腺癌 2 18例 ( 77 0 % ) ,未分化癌 15例 ( 5 3 % ) ,鳞癌 6例 ( 2 1% ) ,粘液腺癌 4例 ( 1 4 % ) ,腺瘤癌变 2 3例 ( 8 1% )。结论 直肠癌发生率最高 ,直肠指检对于发现低位直肠癌有重要意义。为提高早期大肠癌的诊断率 ,应加强对大肠癌高危人群的管理和对大肠癌癌前病变的监测
Objective To retrospectively analyze the clinical, endoscopic and pathological data of colon cancer patients detected by colonoscopy. Methods There were 156 males and 12 7 females with an average age of 576 years. At the time of treatment, the main complaints were bloody stools, diarrhea, abdominal pain and abdominal mass. All colonic examinations were performed using Olympus PCF-20I, CF-30I colonoscopy and Olympus CF-IOI colonoscopy. Results Among 137 cases (44.4%) of rectal cancer, 48 cases (17.0%) of sigmoid colon cancer, 24 cases (85%) of descending colon cancer, and 42 cases (14.8%) of horizontal colon cancer. There were 31 cases of colon cancer (110%) and 1 case of ileocecal cancer (04%). Histology showed adenocarcinoma in 18 cases (77.0%), undifferentiated carcinoma in 15 cases (5.3%), squamous cell carcinoma in 6 cases (2%), mucinous adenocarcinoma in 4 cases (1.4%), and adenoma canceration 2 Three patients (8 1%). Conclusions The highest incidence of rectal cancer, rectal examination is of great significance for the detection of low rectal cancer. In order to improve the diagnostic rate of early colorectal cancer, the management of high-risk colon cancer patients and the monitoring of colorectal cancer precancerous lesions should be strengthened.
