Abstract

PURPOSE: Severe hepatic injury due to gunshot (GSW) compared to blunt mechanism may have significantly different presentation, management, complications, and outcomes. The aim of this study was to identify the differences.

METHODS: Retrospective single-center analysis June 1, 2015-June 30, 2020, included all patients with Grade III-V liver injuries due to GSW or blunt mechanism. Clinical characteristics, severity of injury, liver-related complications (rebleeding, necrosis/abscess, bile leak/biloma, pseudoaneurysm, acute liver failure) and overall outcomes (mortality, hospital length of stay, intensive care unit length of stay, and ventilatory days) were compared.

RESULTS: Of 879 patients admitted with hepatic trauma, 347 sustained high-grade injury and were included: 81 (23.3%) due to GSW and 266 (76.7%) due to blunt force. A significantly larger proportion of patients with GSW were managed operatively (82.7 vs. 36.1%, p < 0.001). GSW was associated with significantly more liver-related complications (40.7% vs. 27.4%, p = 0.023), specifically liver necrosis/abscess (18.5% vs. 7.1%, p = 0.003) and bile leak/biloma (12.3% vs. 5.3%, p = 0.028). On subgroup analysis, in patients with grade III injury, the incidence of liver necrosis/abscess and bile leak/biloma remained significantly higher after GSW (13.9% vs. 3.1%, p = 0.008 and 11.1% vs. 2.5%, p = 0.018, respectively). In sub analysis of 88 patients with leading severe liver injuries, GSW had a significantly longer hospital length of stay, ICU length of stay, and ventilator days.

CONCLUSION: GSW mechanism to the liver is associated with a higher incidence of liver-related complications than blunt force injury.
