多层螺旋CT引导下经皮穿刺活检术的临床应用优势分析

Clinical application advantages analysis of multi-slice spiral CT guided percutaneous biopsy

目的探讨多层螺旋CT(MSCT)引导下经皮穿刺活检术的临床应用优势。方法选取我院2013年1月~2016年12月行CT引导下经皮穿刺活检术的60例病例,随机分为研究组和对照组,各30例。研究组行MSCT定位引导下穿刺活检,通过三维重建对病灶结构及周围组织关系进行分析;对照组采用常规CT轴位定位引导下穿刺活检。比较两组的一次穿刺成功率、重复穿刺率、病理检出率、穿刺精确度分级及并发症发生率。结果研究组的一次穿刺成功率明显高于对照组,差异有统计学意义(P<0.05)。研究组的重复穿刺率及并发症发生率低于对照组,差异有统计学意义(P<0.05)。两组的病理检出率、穿刺精确度分级比较,差异无统计学意义(P>0.05)。结论 MSCT引导下经皮穿刺活检术定位更精确,穿刺更安全,进针点与穿刺路径规划更合理,一次穿刺成功率高,重复穿刺率及并发症发生率低,与传统CT引导下穿刺活检方法比较,MSCT引导下经皮穿刺活检术具有明显临床优势。

Objective To explore clinical application advantages of multi-slice spiral CT （MSCT） guided percutaneous biopsy.Methods 60 patients who were performed CT guided percutaneous biopsy in our hospital from January 2013 to December 2016 were selected and randomly divided into the study group and the control group,30 cases in each group. The study group was given MSCT guided biopsy,and structure and surrounding tissue of the lesion was analyzed by three-dimensional reconstruction.The control group was given routine CT axial position guided biopsy.The success rate of the first puncture,the rate of repeated puncture,the rate of pathological detection,the classification of puncture accu- racy and the incidence rate of complications were compared between the two groups.Results The success rate of the first puncture in the study group was significantly higher than that in the control group,with significant difference （P〈 0.05）.The repeated puncture rate and the incidence rate of complications in the study group was lower than that in the control group,with significant difference （P〈0.05）.There was no significant difference between the two groups in the rate of pathological detection and the classification of puncture accuracy （P〉0.05）.Conclusion The positioning of MSCT guided percutaneous biopsy is more accurate,more safe and more reasonable for the insertion point and puncture path planning. The success rate of the first puncture is high,and the rate of repeated puncture and complications are low.Comparison with traditional CT guided biopsy,MSCT guided percutaneous biopsy has obvious clinical advantages.
