Introduction: Large-bore chest tubes are usually applied after thoracic surgery. Recently, small-bore tubes have been increasingly considered owing to the extensive use of video-assisted thoracoscopic surgery (VATS). This study assessed the differences in outcomes between large-bore and small-caliber drainage tubes in patients undergoing surgical stabilization of rib fractures (SSRF) with VATS.
Methods: Overall, 131 patients undergoing SSRF with VATS were prospectively enrolled, including 65 patients receiving 32-Fr chest tubes (group 1) and 66 patients receiving 14-Fr pigtail catheters (group 2) for postoperative drainage. The clinical characteristics and perioperative outcomes of the patients were compared.
Results: All patients underwent SSRF with VATS within 4 days after trauma. After the operation, the mean duration of chest tubes was longer than that of pigtail catheters, with statistical significance (5.08 ± 2.47 vs 3.11 ± 1.31, P = 0.001). Length of stay (LOS) was also longer in group 1 (10.38 ± 2.90 vs 8.18 ± 2.44, P = 0.001). After multivariate logistic regression, the only independent factors between the two groups were duration of postoperative drainage (adjusted odds ratio [AOR] 1.746; 95% confidence interval [CI] 0.171-10.583, P = 0.001) and hospital LOS (AOR 1.272; 95% CI 0.109-4.888, P = 0.027).
Conclusion: After reconstruction of the chest wall and lung parenchyma, small-caliber drainage catheters could be easily and safely applied to reduce hospital LOS.
