Delaplain PT, Barrios C, Spencer D, et al. - Given the prior guidelines surrounding abdominal seat belt sign (SBS) which were made prior to the use of modern computed tomography (CT) imaging, researchers prospectively examined if a negative CT scan is correlated with the absence of hollow viscus injury (HVI). Further, they examined the possibility of the presence of an HVI among trauma patients with an abdominal SBS without CT imaging findings. They compiled a prospective cohort of patients with SBS and divided them into those with and without HVI. They identified 220 patients with SBS with HVI incidence of 7% (n = 15). Relative to previous reports, this work reported lower incidence of HVI with SBS, and there was no patients with negative CT imaging who required an operation for HVI. This suggests that there is likely a subset of patients with SBS who could be safely discharged from the emergency room.
