Ten-year experience of splenic trauma in New Zealand: the rise of non-operative management.

AIM: The aim of this study was to describe the demographics, mechanisms of injury, management and outcomes in patients who suffered splenic trauma in Christchurch, New Zealand.

METHODS: A retrospective study included all splenic injury patients admitted to Christchurch Public Hospital between January 2005 and August 2015.

RESULTS: A total of 238 patients were included, with a median age of 26 years (4-88.7). Of these, 235 patients had blunt injuries. Eighty-nine had high-grade injuries. Yearly admissions of splenic trauma patients have gradually increased. A total of 173 (72.7%) patients were managed with observation; 28 patients (11.8%) had radiological intervention and 37 patients (15.5%) had splenectomy. Patients who died were significantly more likely to be older (median, 46.5 vs 25.2 years, p=0.04) and to have been admitted to ICU (100% vs 32%, p=<0.001).

CONCLUSION: Splenic injuries have shown a steady increase in the last decade. Splenectomy rates have decreased in favour of non-operative techniques. Radiological intervention with splenic artery embolisation was successful in all selected patients with high-grade injuries.
