Abstract

Objective To compare the evaluation effects of abdominal enhanced computed tomography (CT) coronal imaging versus three-dimensional (3D) vascular reconstruction for critical blood vessels in right colon cancer. Methods The retrospective and descriptive study was conducted. The clinicopathological data of 50 patients with right colon cancer who were admitted to Changhai Hospital Affiliated to Naval Medical University from January to September in 2018 were collected. There were 33 males and 17 females, aged from 33 to 86 years, with an average age of 63 years. All the 50 patients underwent abdominal multi-slice CT examination on the same CT equipment. The CT examination data were analyzed by two-dimensional (2D) coronal imaging and 3D vascular reconstruction. Observation indicators: (1) anatomical type of Henle trunk; (2) the length of Henle trunk and surgical trunk; (3) the positional relationship between ileocolic vein (ICV) and ileocolic artery (ICA). Measurement data with normal distribution were represented as Mean±SD, and count data were represented as absolute numbers. Kappa coefficients were used to measure the consistency between anatomical types of Henle trunk on 2D coronal images and on 3D vascular reconstructed images. Pearson coefficients were used to evaluate the correlation between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images. Bland-Altman method was used to assess the consistency between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images. Results (1) Anatomical type of Henle trunk: on the 2D coronal images, 43 of 50 patients had the Henle trunk and 7 had no Henle trunk. On the 3D vascular reconstructed images, 44 of 50 patients had the Henle trunk and 6 had no Henle trunk. There were 2, 21, 17, 3 patients classified as type 0, Ⅰ, Ⅱ, Ⅲ of Henle trunk on the 2D coronal images of 43 patients.

Six patients with no Henle trunk, 2 in type 0, 18 in type Ⅰ, 15 in type Ⅱ, and 3 in type Ⅲ had the same anatomical type of Henle trunk on the 2D and 3D images. The consistency between anatomic types of Henle trunk on 2D coronal images and on 3D vascular reconstructed images was high (κ=0.830, 95% confidence interval: 0.705-0.956, P<0.05).

There was a complete consistency in the positional relationship between ICV and ICA on the 2D coronal images and on 3D vascular reconstructed images. Conclusion Abdominal enhanced CT coronal imaging and 3D vascular reconstruction have the similar evaluation effects for position of critical blood vessels in right colon cancer, with a good consistency.

腹部增强CT二维冠状面成像与三维血管重建对右结肠癌关键血管术前评价效果的比较

目的比较右结肠癌患者腹部增强CT冠状位成像与三维血管重建对关键血管的评价效果。方法采用回顾性和描述性研究。收集海军医科大学附属长海医院2018年1月至9月收治的50例右半结肠癌癌症患者的临床病理资料。33名男性和17名女性，年龄从33岁到86岁，平均年龄63岁。所有50例患者均在同一台CT设备上进行了腹部多层螺旋CT检查。通过二维冠状动脉成像和三维血管重建对CT检查数据进行分析。观察指标：（1）母鸡躯干解剖类型；（2） Henle干和外科干的长度；（3）回盲静脉（ICV）与回盲动脉（ICA）的位置关系。正态分布的测量数据表示为Mean±SD，计数数据表示为绝对数。Kappa系数用于测量Henle干在2D冠状图像和3D血管重建图像上的解剖类型之间的一致性。Pearson系数用于评估Henle干和外科干在2D冠状图像和3D血管重建图像上的长度之间的相关性。Bland-Altman方法用于评估Henle干和外科干的长度在2D冠状图像和3D血管重建图像上的一致性。结果（1）Henle干的解剖类型：在二维冠状图像上，50例患者中有43例有Henle干，7例没有Henle干。在三维血管重建图像上，50例患者中有44例有Henle干，6例没有Henle干。在43例患者的二维冠状图像上，Henle干分为0型、Ⅰ型、Ⅱ型、Ⅲ型2例、21例、17例、3例。在44例Henle干的三维血管重建图像中，有6例、19例、16例、3例患者分为0型、Ⅰ型、Ⅱ型、Ⅲ型。6例无Henle干，0型2例，Ⅰ型18例，Ⅱ型15例，Ⅲ型3例。Henle干和手术干的长度：在2D冠状图像上，50例患者中有43例Henle干的长度为（10±5）mm，50例中有42例手术干的长为（34±12）mm。在三维血管重建图像上，50例患者中有44例的Henle干长度为（9±5）mm，50例中有43例的手术车长度为（35±12）mm。Henle干与手术干的长度在二维冠状图像和三维血管重建图像上呈正相关（r=0.872，0.979，P<0.05）。Bland-Altman图显示，Henle干和手术干在二维冠状和三维血管重构图像上的长度高度一致（P<0.05）冠状位图像显示，50例患者中有24例ICV与ICA前交叉，26例ICV和ICA后交叉。在三维血管重建图像上，50例患者中有24例出现ICV和ICA之间的前交叉，26例出现ICV-ICA之间的后交叉。在二维冠状图像和三维血管重建图像上，ICV和ICA之间的位置关系完全一致。结论腹部增强CT冠状位成像与三维血管重建对癌症临界血管位置的评价效果相似，具有较好的一致性。关键词：结肠肿瘤；右结肠癌癌症；关键容器；评估；计算机断层扫描；三维血管重建；一致性；分析；母鸡胃绞痛干
