    [摘要] 早期结直肠癌可通过内镜黏膜切除术(EMR)或内镜黏膜剥离术(ESD)治疗，但如果术后病理显示存在预后不良的危险因素，则需追加根治性手术。在结直肠癌根治手术中，提高转移淋巴结的检出率及清除率对判断肿瘤分期、改善预后等意义重大。纳米碳淋巴示踪技术能够对淋巴结进行染色定位，提高根治术中淋巴结的检出率。现报道1例内镜黏膜剥离术后追加纳米碳淋巴染色辅助下腹腔镜结肠癌切除术，治疗乙状结肠癌患者的诊疗经过，通过对此病例的分析，以期对临床工作有所帮助。

    [Abstract] Early colorectal cancer can be treated by endoscopic mucosal resection(EMR) or endoscopic submucosal dissection(ESD). However， if postoperative pathology shows that there are risk factors for poor prognosis， additional radical surgery is required. In radical surgery for colorectal cancer， improving the detection rate and clearance rate of metastatic lymph nodes is of great significance for judging tumor staging and improving prognosis. Nanocarbon lymphatic tracer technique can stain and locate lymph nodes and improve the detection rate of lymph nodes during radical surgery. The treatment process of one case of patient in the treatment of sigmoid colon cancer is reported undergoing laparoscopic colon cancer resection assisted by nanocarbon lymphatic staining after ESD. Through the analysis of this case ......
