Assessment of nonoperative management of blunt spleen and liver trauma.

An 8-year analysis of nonoperative management (NOM) of spleen and liver trauma was done in a level 1 trauma center. Spleen and liver trauma was diagnosed in 279 patients: 93 children (<18), 137 younger adults (18-54), and 49 older adults (> or = 55). Nineteen patients who failed resuscitations died within 0-60 minutes of arrival and were excluded from treatment analysis. Operative management (OM) was done in 39 (15%) and NOM in 221 (85%) patients with failure (NOMF) in 11 (5%). NOM and NOMF was 82 per cent and 5.6 per cent in spleen, 74 per cent and 14.3 per cent in combined spleen/liver, and 96 per cent and 1.5 per cent in liver trauma (P value <0.001). NOM was done in 99 per cent of children, 81 per cent of younger adults, and 68 per cent of older adults with 0 per cent, 8 per cent, and 10 per cent NOMF. Higher grades of splenic trauma and CT fluid had higher OM rate. NOM success rates were 93.8 per cent in grade 3 and 90.3 per cent in higher grades of spleen trauma. There was no NOMF in higher grades of liver trauma. CT fluid grade had no impact on NOMF. Female patients had higher mean injury severity score, age, and mortality compared to cohorts. NOM should be attempted in hemodynamically stable patients. Age over 55, higher grades of injury, and large hemoperitoneum were not predictors of failure of NOM.
