OBJECTIVES: Non-operative management has become the treatment of choice in the majority of liver injuries. The aim of this study was to assess the changes in primary treatment and outcomes in a single Dutch Level 1 trauma centre with wide experience in angio-embolisation (AE). METHODS: The prospective trauma registry was retrospectively analysed for 7-year periods before (Period 1) and after (Period 2) the introduction of AE. The primary outcome was the failure rate of primary treatment defined as liver injury-related death or re-bleeding requiring radiologic or operative (re)interventions. Secondary outcomes were liver injury-related intra-abdominal complications. RESULTS: Despite an increase in high-grade liver injuries, the incidence of primary non-operative management more than doubled over the two periods, from 33% (20 of 61 cases) in Period 1 to 72% (84 of 116 cases) in Period 2 (P < 0.001). The failure rate of primary treatment in Period 1 was 18% (11/61), compared with 11% (13/116) in Period 2 (P= 0.21). Complication rates were 23% (14/61) and 16% (18/116) in Periods 1 and 2, respectively (P= 0.22). Liver-related mortality rates were 10% (6/61) and 3% (4/116) in Periods 1 and 2, respectively (P= 0.095). The increase in the frequency of non-operative management was even higher in high-grade injuries, in which outcomes were improved. In high-grade injuries in Periods 1 and 2, failure rates decreased from 45% (9/20) to 20% (11/55) (P= 0.041), liver-related mortality decreased from 30% (6/20) to 7% (4/55) (P= 0.019) and complication rates fell from 60% (12/20) to 27% (15/55) (P= 0.014). Liver infarction or necrosis and abscess formation seemed to occur more frequently with AE. CONCLUSIONS: Overall, liver-related mortality, treatment failure and complication rates remained constant despite an increase in non-operative management. However, in high-grade injuries outcomes improved after the introduction of AE.
