摘　　要：目的:旨在探讨靶点靶线体表描记法在CT引导经皮肺穿刺活检术中的技术要点及应用价值。方法:选取2021年8月至2022年4月进行肺穿刺活检的病例152例,随机分为A组(77例,采用靶点靶线体表描记法穿刺)和B组(75例,常规穿刺法),比较2组首次进针成功率、CT扫描次数、诊断准确率、术后并发症及手术时间以评估2种手术方法效果。结果:2组均穿刺成功并取得标本,穿刺成功率均为100%。首次进针成功:A组64例,B组62例,2组间无统计学差异(χ^(2)=0.005,P=0.941);CT扫描次数超标:A组18例,B组54例,2组间有统计学差异(χ^(2)=36.030,P<0.05);诊断准确:A组70例,B组68例,2组间无统计学差异(χ^(2)=0.003,P=0.959);咯血:A组12例,B组9例,2组间无统计学差异(χ^(2)=0.410,P=0.522);气胸:A组10例,B组11例,2组间无统计学差异(χ^(2)=0.090,P=0.764);手术时间:A组平均(19.88±4.47) min,B组平均(32.23±4.95) min,2组间有统计学差异(t检验,P<0.05)。结论:CT引导肺穿刺术中应用靶点靶线体表描记法简单易行,能准确指导CT引导肺穿刺术中穿刺角度的把握,减少术中CT扫描次数,值得在临床中推广。Objective:To investigate the key technical issues and application value of target line surface tracing in CT-guided percuta⁃neous lung biopsy.Methods:A total of 152 patients who underwent lung biopsy from August 2021 to April 2022 were enrolled and ran⁃domly divided into group A with 77 patients and group B with 75 patients.The efficacy of the two surgical methods was evaluated by comparing the two groups in terms of the success rate of first-time needle insertion,the number of CT scans,diagnostic accuracy,post⁃operative complications,and time of operation.Results:Both groups A and B had successful puncture with specimens obtained,and the success rate of puncture was 100%.Successful first-time needle insertion was achieved for 64 patients in group A and 62 in group B,with no significant difference between the two groups(χ^(2)=0.005,P=0.941);18 patients in group A and 54 in group B had an excessive number of CT scans,with a significant difference between the two groups(χ^(2)=36.030,P<0.05);70 patients in group A and 68 in group B achieved an accurate diagnosis,with no significant difference between the two groups(χ^(2)=0.003,P=0.959).Hemoptysis was ob⁃served in 12 patients in group A and 9 patients in group B,with no significant difference between the two groups(χ^(2)=0.410,P=0.522),and pneumothorax was observed in 10 patients in group A and 11 patients in group B,with no significant difference between the two groups(χ^(2)=0.090,P=0.764).The mean time of operation was(19.88±4.47)minutes in group A and(32.23±4.95)minutes in group B,and there was a significant difference between the two groups(t-test,P<0.05).Conclusion:The application of target line surface tracing in CT-guided lung puncture is simple and easy and can accurately guide the angle of puncture and reduce the number of CT scans during surgery,and therefore,it holds promise for clini⁃cal application.
