Factors Associated with Successful Video-Assisted Thoracoscopic Surgery and Thoracotomy in the Management of Traumatic Hemothorax.

BACKGROUND

Few studies have identified factors associated with successful VATS or thoracotomy as the initial operative strategy among patients with traumatic hemothorax.

MATERIAL AND

METHODS

We performed an exploratory analysis using the 2008 to 2017 TQP database. We identified all patients aged 18 to 89 years with traumatic hemothorax who were treated with tube thoracostomy alone in the first 24-hours of admission, followed by VATS or thoracotomy. Logistic regression was used to identify factors associated with successful VATS (no conversion or reoperation) or thoracotomy (no reoperation) as the initial operative strategy.

RESULTS

Among 2052 patients managed with initial VATS after chest tube drainage, 1710 (83%) were successful, while 263 (13%) were converted to thoracotomy and 79 (4%) required reoperation. On multivariable analysis, poor GCS (OR = 0.96 [95% CI = 0.94-0.99]), major injury (OR = 0.69 [95% CI = 0.53-0.90]), and diaphragmatic injury (OR = 0.42 [95% CI = 0.30-0.60]) were associated with lower odds of successful VATS, while rib fractures (OR=1.29 [95% CI=1.01-1.66]) were associated with higher odds of success of the initial operative plan. Among 3486 patients initially managed with thoracotomy after drainage with tube thoracostomy, 3118 (89.4%) were successful, while 11% (n = 368) required reoperation. Multivariable analysis revealed that major injury (OR = 0.68 [95% CI = 0.50-0.92]), blunt mechanism (OR = 0.63 [95% CI = 0.50-0.78]), and diaphragmatic injury (OR = 0.67, 95% CI = 0.53-0.84]) were associated with lower odds of successful thoracotomy as the initial operative plan.

CONCLUSIONS

More severe injuries and diaphragmatic injuries have lower odds of successful of VATS or thoracotomy as the initial operative management strategy among patients with traumatic hemothorax. Rib fractures may be associated with higher odds of success of VATS as the initial management strategy.
