Background There are no established guidelines regarding the optimal size of chest tubes following a bullectomy. While large chest tubes are commonly used after bullectomy, several studies have shown that pigtail catheters can be effectively employed for postoperative drainage in lung cancer surgery. This study aimed to compare the time to tube removal between an 8Fr pigtail catheter and a 24Fr chest tube after bullectomy to assess the non-inferiority of the 8Fr pigtail catheter. Methods Data from 32 patients aged 14-30 years who underwent bullectomy between April 2020 and April 2023 were analyzed. Participants were assigned to receive either an 8Fr pigtail catheter (n = 10) or a 24Fr chest tube (n = 22). The primary outcome measured was the number of days until tube removal. Results The mean time to tube removal was 1.2 days in the 8Fr group and 1.5 days in the 24Fr group, meeting the non-inferiority margin of one day (mean difference: -0.3 days, 95% CI: -0.78, 0.18). No major complications were observed in either group. Conclusions An 8Fr pigtail catheter appears to be a non-inferior alternative to the 24Fr chest tube for postoperative drainage following bullectomy.
关于肺大疱切除术后胸管的最佳尺寸，目前尚无既定指南。虽然肺大疱切除术后通常使用大口径胸管，但多项研究表明，猪尾导管可有效用于肺癌手术的术后引流。本研究旨在比较肺大疱切除术后8Fr猪尾导管和24Fr胸管的拔管时间，以评估8Fr猪尾导管的非劣效性。方法：分析2020年4月至2023年4月期间32例年龄在14至30岁之间接受肺大疱切除术患者的数据。参与者被分配接受8Fr猪尾导管（n = 10）或24Fr胸管（n = 22）。测量的主要结局是直至拔管的天数。结果：8Fr组的平均拔管时间为1.2天，24Fr组为1.5天，达到了一天的非劣效性界限（平均差值：-0.3天，95%CI：-0.78，0.18）。两组均未观察到重大并发症。结论：对于肺大疱切除术后的术后引流，8Fr猪尾导管似乎是24Fr胸管的非劣效替代方案。
