结直肠癌是男性中第三大最常见的癌症,在女性中排名第二。仅在美国,每年有15万例确诊病例。结肠镜检查仍然是最好的鉴别方法,评估,并对癌前病变患者进行干预。多种指南和技术可用于协助内窥镜医师准确诊断这些病变。其中包括巴黎,窄带成像(NBI)国际结直肠内镜(NICE),日本NBI专家团队(JNET)Kudo,广岛,和Shudo分类利用诸如色素内窥镜检查之类的技术,窄带成像,和细胞内镜检查以评估凹坑模式和表面形态。利用这些工具可以帮助内窥镜医师预测结肠病变的细胞学,并选择最合适的切除方法,同时最大程度地保留器官。
Colorectal cancer is the third most common cancer among men and the second among women. In the United States alone, there are 150,000 cases diagnosed each year. Colonoscopy remains the best method for identifying, evaluating, and intervening on patients with precancerous lesions. Multiple guidelines and
techniques are available to assist the endoscopist with accurate diagnosis of these lesions. These include the Paris, Narrow-Band Imaging (NBI) International Colorectal Endoscopic (NICE), Japan NBI Expert Team (JNET), Kudo, Hiroshima, and Shudo classifications which utilize
techniques such as chromoendoscopy, narrow-band imaging, and endocytoscopy to evaluate pit pattern and surface morphology. Utilization of these tools can help the endoscopist predict the cytology of a colonic lesion and select the most appropriate method for resection while maximizing organ preservation.
