摘　　要：目的:探讨256层螺旋CT用于术前评估腹腔镜结直肠癌手术者肠系膜血管解剖结构的临床价值。方法:选取2021年2月至2023年2月于我院就诊的48例结直肠癌患者作为研究对象,患者均接受腹腔镜结直肠癌根治术治疗,术前均行256层螺旋CT检查评估肠系膜解剖结构,将术前CT检查结果与手术结果进行对照,分析CT术前评估准确度。结果:术前螺旋CT评估肠系膜下动脉(IMA)及分支解剖走形分型结果与手术结果完全一致,吻合率为100%。术前螺旋CT评估肠系膜空间关系与手术结果的一致性高(Kappa值=0.916,P<0.001)。结论:256层螺旋CT检查用于术前评估腹腔镜结直肠癌手术者肠系膜血管解剖结构,具有较高的准确性,能清晰显示IMA走形及左结肠静脉与肠系膜下静脉的空间关系,对指导临床具有重要作用。Objective To investigate the clinical value of 256-slice spiral CT in preoperative evaluation of mesenteric vascular anatomy in laparoscopic colorectal cancer surgery.Methods Total 48patients with colorectal cancer who were treated in our hospital from February 2021to February 2023were selected as the research objects.All patients received laparoscopic radical resection of colorectal cancer and underwent 256-slice spiral CT examination to evaluate the mesenteric anatomy before operation.The results of preoperative CT examination were compared with the surgical results to analyze the accuracy of preoperative CT evaluation.Results The results of preoperative spiral CT evaluation of the anatomical route of the inferior mesenteric artery(IMA)and its branches were completely consistent with the surgical results,with the agreement rate of 100%.The surgical results were highly consistent with the preoperative spiral CT examination results of the spatial relationship of the mesentery(Kappa value=0.916,P<0.001).Conclusion The 256-slice spiral CT examination is used for preoperative evaluation of the mesenteric vascular anatomy in laparoscopic colorectal cancer surgery,with high accuracy.It can clearly show the route of IMA and the spatial relationship between the left colonic vein and the inferior mesenteric vein,which has an important role in guiding the clinical practice.
