Percutaneous pigtail catheter versus chest tube for the treatment of pediatric traumatic hemothorax: An Eastern Association for the Surgery of Trauma multicenter study.

BACKGROUND

Small percutaneously placed pigtail catheters (PCs) for traumatic hemothorax (HTX) are safe and effective in adults but have not been evaluated in children. We hypothesized that PC would have similar efficacy and complication rates compared with chest tubes (CTs).

METHODS

A retrospective study of hemodynamically stable pediatric trauma patients (younger than 18 years) with HTX or hemopneumothorax was conducted at 41 trauma centers (January 2010 to December 2022). Catheter failure was defined as a requirement for surgery, additional tube placement, or thrombolytics. Multivariable logistic regression analysis adjusting for age, sex, mechanism of injury, and Injury Severity Score (ISS) was used to evaluate the associated risk of failure.

RESULTS

Of 548 patients, 477 had CT and 71 PC. The median age (CT: 15.7 vs. PC: 15.6, p = 0.49) and ISS (CT: 17 vs. PC: 16, p = 0.17) were similar between cohorts. Penetrating trauma patients more often received CTs (62.6% vs. 35.2%, p < 0.0001). Failure rate was similar between CT versus PC (17.6% vs. 12.6%, p = 0.38). While the overall complication rate (respiratory distress, effusion, empyema, pneumonia, infection, deep venous thrombosis) was higher in the PC group on univariate analysis (19.7% vs. 11.9% in CT, p = 0.02), the risk of complications was not increased on multivariable analysis (odds ratio, 1.05; 95% confidence interval, 0.95-1.15; p = 0.3). Length of stay and intensive care unit length of stay were similar between cohorts (all p > 0.05). Logistic regression analysis revealed that PC was not associated with the risk of failure (odds ratio, 0.95; 95% confidence interval, 0.87-1.04; p = 0.31). There was an increased risk of complications with ISS of >15 (odds ratio, 1.17; 95% confidence interval, 1.10-1.26; p < 0.0001) and lower risk with penetrating injury (odds ratio, 0.86; 95%confidence interval, 0.80-0.92; p = 0.0001).

CONCLUSION

There was no difference in risk of failure between PC and CT for pediatric HTX/hemopneumothorax and no difference in risk of complications after adjustment for confounders. Pigtail catheters had similar safety and efficacy compared with larger-bore CTs in this large multi-institutional study.
