目的
2
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
2
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
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

结论
2
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
2
To investigate the key technical issues and application value of target line surface tracing in CT-guided percutaneous lung biopsy.
Methods
2
A total of 152 patients who underwent lung biopsy from August 2021 to April 2022 were enrolled and randomly 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,postoperative complications,and time of operation.
Results
2
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 observed 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
2
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 clinical application.
