ABSTRACT
INTRODUCTION: Chest drainage remains an important intervention for pneumothorax when conservative or ambulatory management is not suitable. Although chest drain techniques have been widely studied, contemporary real-world data from Southeast Asia remain limited, particularly in populations with a high burden of secondary pneumothorax related to infectious lung disease.
MATERIALS AND METHODS: We conducted a retrospective cohort study of adult pneumothorax patients who underwent intercostal chest drain insertion at Sibu Hospital, Sarawak, Malaysia, between January 2021 and February 2024. Patients were managed with either conventional trocar chest tubes or Seldinger wire-guided drains. The primary outcome was chest drain-related complications. Secondary outcomes included chest drain duration, hospital length of stay, persistent air leak (PAL >5 days) and mortality. Continuous variables were analysed using independent ttests and categorical variables using chi-square or Fisher’s exact tests. Multivariate logistic regression was performed to identify predictors of subcutaneous emphysema, and multiple linear regression was used to evaluate factors associated with chest drain duration.
RESULTS: A total of 123 patients were included (86 conventional and 37 Seldinger). Subcutaneous emphysema occurred significantly less frequently in the Seldinger group (5.4% vs 55.8%, p<0.001). Mean chest drain duration was shorter in the Seldinger group (8.86 ± 7.10 vs 10.34 ± 11.96 days, p=0.032). Differences in insertion failure (0% vs 8.1%, p=0.074), tube dislodgement (2.7% vs 11.6%, p=0.112), persistent air leak >5 days (67.6% vs 54.7%, p=0.182) and mortality (10.8% vs 15.1%, p=0.518) were not statistically significant. Multivariate logistic regression identified conventional chest drainage as an independent predictor of subcutaneous emphysema (OR 27.6, 95% CI 5.24-145.94; p<0.001). Multiple linear regression demonstrated that conventional drainage, non-tension pneumothorax, smoking and persistent air leak were independently associated with longer chest drain duration.
CONCLUSION: In this retrospective cohort, the Seldinger technique was associated with lower complication rates and shorter drainage duration compared with conventional chest drainage. Prospective multicentre studies are required to confirm these findings.
