Background: There is variability regarding the utilization and timing of repeat imaging in adult patients with blunt hepatic injury who are managed nonoperatively. This study examines the rate of delayed complications and interventions in patients with blunt hepatic injuries who undergo repeat imaging prompted either by clinical change (CC) or non-clinical change (NCC).
Methods: A nine-year, retrospective, dual-institution study was performed of adult patients with blunt hepatic injuries. Patients were identified based on whether repeat imaging was performed and reason for reimaging: CC or NCC. The incidence of delayed complications and interventions was examined for each type of scan.
Results: Of 365 patients, 122 (33.4%) underwent repeat imaging [CC, n = 72 (59%); NCC, n=50 (41%)]. Mean time to repeat imaging was shorter in the NCC group [CC = 7.6 ± 8 days; NCC = 4.7 ± 6.3 days, P = 0.034]. Delayed complications were found in 30 (25%) patients reimaged, [CC, n = 20; NCC, n = 10, P = 0.395]. Interventions were performed in 12 (40%) patients [CC, n = 10; NCC, n = 2, P = 0.120].
Conclusions: Repeat imaging due to NCC occurred earlier than imaging performed by CC. One quarter of patients reimaged demonstrated a delayed complication, with nearly half undergoing intervention. There was no difference in incidence of delayed complications or interventions between groups, suggesting repeat imaging can be prompted by clinical change in blunt hepatic injuries.
