本研究的目的是主要根据复杂性气胸的持续时间，确定手工抽吸辅助下活检术所致气胸的处理指南。检查了连续388例经皮肺活检的数据。活检术后胸部CT图像显示气胸的患者接受了经皮18G静脉注射气胸。导管。对活检性气胸的发生频率、处理方法及气胸消失的时间进行了综述。在388例手术中，133例(34.3%)发生了活检后气胸。在这133名患者中，有72名患者在活检后立即进行了手工抽吸。133例气胸中121例(91.0%)在未放置胸管的情况下，随访胸片显示气胸完全消失。在需要胸管的病例中，从活检到气胸消失的平均时间为6.0±5.3天，而当不需要放置胸管时仅为2.4±2.9天。具体地说，无论是那些不需要手动抽吸的患者(2.1±3.4天)还是在手动抽吸后气胸完全或几乎完全消失的患者(1.9+/-2.0天)，恢复的时间都很短。不需要手动抽吸的患者和需要立即手动抽吸的患者几乎同样短的恢复期表明了快速处理的价值。
The purpose of this study was to determine management guidelines for biopsy-induced pneumothorax with the assistance of manual aspiration, mainly based on the duration of complicated pneumothorax. Data from 388 consecutive percutaneous needle lung biopsies were examined. Patients with pneumothorax on postbiopsy chest CT images underwent percutaneous manual aspiration with an 18-G i.v. catheter. Frequency and management of biopsy-induced pneumothorax and period to its disappearance were reviewed. Postbiopsy pneumothorax occurred in 133 of 388 (34.3%) procedures. Manual aspiration in 72 of these 133 patients was carried out immediately after biopsy. The pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement in 121 of the 133 pneumothoraces (91.0%). In cases requiring chest tube, the mean period from biopsy until resolution of the pneumothorax was 6.0 +/- 5.3 days, but was only 2.4 +/- 2.9 days when chest tube placement was not needed. Specifically, time until recovery was short both in those not requiring manual aspiration (2.1 +/- 3.4 days) and in those with a pneumothorax that disappeared completely or almost completely after manual aspiration (1.9 +/- 2.0 days). The almost equally short recovery periods in patients not requiring manual aspiration and those requiring immediate manual aspiration indicates the value of rapid management.
