Application of Abdominal Pressure Band in Puncture Biopsy of Small Nodules in the Lower Lung
Objective To study the clinical application value of abdominal pressure band in CT-guided puncture biopsy of lower lung nodules.Methods A retrospective analysis was conducted on 100 patients who underwent lower lung nodule punc-ture biopsy at the Cancer and Radiotherapy Center of Tongji Hospital affiliated to Huazhong University of Science and Technol-ogy from January to December 2022.They were divided into abdominal pressure band group and control group.There were 40 patients in abdominal pressure band group,among which abdominal pressure bands were applied during the puncture process.There were 60 patients in control group who did not use abdominal pressure bands during the puncture process.The CT scan frequency,puncture depth,success rate,intraoperative time,incidence of complications,and radiation dose for puncture biopsy were compared between the two groups.Results The median value of CT scan frequency during puncture biopsy in ab-dominal pressure band group was 5 times,with a success rate of 100％(40/40).The median value of intraoperative time was 7.9 min,and the incidence of complications was 10％(4/40).The median value of radiation dose was 210.4 mGy·cm.The median value of CT scan frequency during puncture biopsy in control group was 8 times,with a success rate of 86.7％(52/60).The me-dian value of intraoperative time was 13 min,and the incidence of complications was 40％(24/60).The median value of radiation dose was 287.7 mGy·cm.Differences in five indicators were statistically significant between the two groups(all P＜0.05).Conclusion Application of the abdominal pressure bands in lower lung nodule puncture biopsy can significantly reduce the number of scans,shorten surgical time,reduce the radiation dose received by patients,and have a higher success rate and lower incidence of complications.Utilization of pressure band should be promoted in clinical practice.
