摘要
目的探讨多层螺旋CT对胃癌术前转移性淋巴结的判定价值。方法分析已确诊胃癌患者术前64层螺旋CT检出淋巴结,分别从淋巴结长径、淋巴结强化程度及淋巴结短长径比值3方面判定淋巴结转移,并与术后病理结果对照。结果以淋巴结长径≥8mm、淋巴结强化程度≥80Hu及淋巴结短长径比值≥0.7作为多层螺旋CT判定转移性淋巴结的标准,与术后病理结果比较,一致性较好。结论多层螺旋CT做为一种简洁、无创的检查方法,依据淋巴结长径、强化程度及淋巴结的形态等指标,对胃癌术前淋巴结转移可以做出初步判断,为临床术前选择合理术式、评估预后及开展新的手术方法均有重要的价值。
Objective To study the value of multi-slice spiral computed tomography （CT） in the preoperative evaluation of lymph node metastasis.Methods Totally 45 patients with gastric cancer detected by 64-slice spiral CT were enrolled in this study.The potential lymph node metastasis was evaluated by measuring or calculating the long diameter,extent of enhancement,and short-to-long diameter ratio of the lymph nodes.The results were compared with postoperative pathological findings.Result A long diameter≥8mm,enhanced density≥80Hu,and short-to-long diameter ratio≥ 0.7 had the best consistency with postoperative pathological findings.Conclusion As a simple and noninvasive technique,multi-slice spiral CT is helpful to identify potential lymph node metastasis of gastric cancer based on long diameter,extent of enhancement,and short-to-long diameter ratio of the lymph nodes,and thus provide important information for surgery selection,prognosis,and development of new procedures.
