Application of target line surface tracing in CT-guided percutaneous lung biopsy

Abstract:

Objective To investigate the key technical issues and application value of target line surface tracing in CT-guided percutaneous lung biopsy.Methods 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 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（χ²=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（χ²=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（χ²=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（χ²=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（χ²=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 clinical application.
