Harfouch N, Stern J, Chowdhary V, et al. - Researchers investigated the utility of an abdominal and/or pelvic ultrasound (US) performed within 24 h after a negative CT of the abdomen and pelvis (CTAP) in the emergency department (ED). Further, they examined whether immediate US reimaging leads to significant increase in length of stay (LOS) in the ED. The imaging reports of 335 patients over the course of 3 years who had an US within 24 h after a negative CTAP were reviewed. Among 335 patients, only three US cases were suspicious for acute surgical pathology (3/335 or 0.9%). They observed no change in surgical management in the acute setting in correlation with US abdomen and/or pelvis reimaging within 24 h following a negative CTAP. US reimaging can still be valuable in diagnosing non-surgical pathology, which may aid in explaining the patient's pain. An average increase in the ED LOS was noted in correlation with performing US reimaging after negative CTAP.
