Corzo et al identified risk factors for operative management of a patient with mesenteric hematoma following blunt abdominal trauma. These can help to identify candidates for nonoperative management. The authors are from the University of Pittsburgh.


Patient selection: adult with blunt abdominal trauma and mesenteric hematoma on CT scan


Exclusion: other intra-abdominal injuries, Glasgow coma score (GCS) < 14


Risk factors for operative management:

(1) abdominal pain (odds ratio 10)

(2) abdominal tenderness (odds ratio 32)

(3) free fluid within the abdomen (odds ratio 10)


Patients with none of these risk factors had nonoperative management with a 100% success rate.
