摘　　要：目的分析早期结直肠癌的白光内镜下特点。方法对北京军区总医院消化内镜中心2010年1月-2015年9月经结肠镜检查发现并经病理证实的早期结直肠癌病例进行回顾性研究,分析其白光内镜下特点。结果共发现早期结直肠癌319处（292例患者）,其中,269例为单发,23例为多原发癌,21例为同时多原发癌,2例为异时多原发癌。早期结直肠癌中228处（71.5%）分布在乙状结肠及直肠。癌灶直径0.4~13 cm,以1.1~2.0 cm最多。隆起型病变（229处,71.8%）明显多于平坦型病变（90处,28.2%）,以0-Ⅰs型最多见。71.9%的0-Ⅰp病变蒂部膨大,26.0%病灶表面可见边界清晰的凹陷,19.4%有基底白斑。259处为黏膜内癌,60处为黏膜下癌。结论早期结直肠癌以左半结肠为主,0-Ⅰs型病变多见。表面边界清晰的凹陷、基底白斑及有蒂息肉蒂部膨大是早期结直肠癌白光内镜下常见的形态特点。Objective To analyze the endoscopic characteristics of early colorectal cancer. Methods Pathological diagnosed early colorectal cancer cases were collected from digestive endoscopy center of Beijing Military Region General Hospital form Jan. 2010 to Sep. 2015, and their endoscopic characteristics were analyzed retrospectively. Results A total of 319 early eolorectal cancer （292 patients） were collected. Two hundred and sixty-nine patients had single carcinomas, while twenty-three patients had multiple primary carcinomas, including twenty-one simultaneous multiple primary carcinomas and two metachronous multiple primary carcinomas. There were 228 cases （71.5%） distributed in the sig- moid colon and rectum. The diameter of cancer lesion was form 0.4 to 13 em, the size was from 1.1 to 2.0 em in the most. The number of protruded lesions （229 cases, 71.8% ） was greater than superficial lesions, 0- I s was the most common type. 71.9% of 0- I p lesions had stalk swelling, 26.0% of early colorectal cancer had clear boundary demarcated depressed area on the surface, 19.4% had white patches exist around the lesion. Two hundred and fifty-nine ca- ses were intramucosal carcinoma, while sixty cases were submucosal cancer. Conclusion Most of early colorectal cancer are in left colon, and the most common macroscopic morphology is 0- I s type. Early colorectal cancer with clear boundary demarcated depressed area, white patches exist around the lesion, 0- I p lesions with stalk swelling are the main morphological characteristics under the white light endoscopy.
