Evaluation of liver injury in a tertiary hospital: a retrospective study.

BACKGROUND: Liver is the most frequently injured intraabdominal organ following abdominal trauma. Liver injury in polytraumatized patients can vary from minor contusions to major lacerations and is associated with morbidity and mortality. The objective of this study was to evaluate the outcome of liver injury in polytraumatized patients.

METHODS: Only surgically treated 82 patients with liver injury over an eight year period (2005-2013) were included in this study and analyzed retrospectively. Data collected included demographics, laboratory findings, intraoperative findings, operative management, and outcome. The patients were divided into two groups and the mortality and survival data were compared.

RESULTS: The overall mortality rate was 18.3% (15 of 82 patients). 34 (41.5%) patients had blunt, forty-eight (48.5%) had penetrating trauma. There were multiple traumas in forty-seven (57%) patients. Forty-seven (57%) patients had total of seventy one coexisting intraabdominal injuries. Forty-six (56.1%) patients had stable and thirty-six (43.9%) had unstable hemodynamics on admission. In mortality group AST, ALT, LDH, APTT, PT, INR, and creatinine levels were high, fibrinogen levels and platelet counts were low on admission.

CONCLUSION: Hemodynamic instability, coexisting musculoskeletal and chest injury, high APTT, PT, INR, AST, ALT, LDH levels, and low fibrinogen levels and platelet counts on admission should be considered as predictive factors for mortality.
