背景资料：CT结肠成像（CTC）是可行的大肠息肉的筛查报告，但其在术前检查的有效性仍然未知。这项研究的目的是定义我们的CTC方法并评估CTC用于结肠癌患者术前检查的潜力。方法：2014年2月至2015年11月，共有86名结肠癌患者在我科接受腹腔镜结肠切除术前接受了CTC。将CTC确定的原发性结肠癌的位置与手术中确认的位置进行比较。术前结肠镜检查后立即进行CTC;对于小结肠癌，我们在结肠镜检查期间进行了夹闭，以提高CTC的检测能力。我们分类壁畸形，并比较它们与病理T stage.Results：CTC准确定位所有87原发性结肠癌手术前。没有患者发生与CTC相关的并发症。畸形分类与病理T分期显著相关（p <0.001，Kruskal-Wallis非参数检验）。CTC提供了重建图像描绘原发性结肠癌的供血动脉;通过CTC获得的供血动脉信息有助于精确的淋巴结清扫。结论：CTC似乎是一种可行的和有用的结肠癌治疗的术前检查模式。(C)2016年亚洲外科协会和台湾机器人外科协会。出版社：Elsevier B.V.
Background: Computed tomographic colonography (CTC) is reported to be feasible for screening of colorectal polyps; however, its efficacy in preoperative workup remains unknown. This study was done to define our CTC methodology and assess CTC's potential for preoperative examination in patients with colon cancer.Methods: A total of 86 colon cancer patients underwent CTC prior to laparoscopic colectomy in our department from February 2014 to November 2015. The location of primary colon cancer determined by CTC was compared with that confirmed during the surgery. CTC was performed just after preoperative colonoscopy; for a small colon cancer, we performed clipping during colonoscopy to enhance CTC detectability. We classified wall deformities and compared them with the pathological T stage.Results: CTC accurately located all 87 primary colon cancers prior to surgery. No patient experienced complications associated with CTC. The deformity classification correlated significantly with the pathological T stage (p < 0.001, Kruskal-Wallis nonparametric tests). CTC provided reconstructed images depicting the feeding artery of the primary colon cancer; feeding artery information obtained by CTC facilitated precise lymph node dissection.Conclusion: CTC appears to be a feasible and useful preoperative examination modality for colon cancer treatment.
