  • Title: The role of computed tomography in diagnosis of blunt intestinal and mesenteric trauma (BIMT).
    Author: Sharma OP, Oswanski MF, Singer D, Kenney B.
    Journal: J Emerg Med; 2004 Jul; 27(1):55-67. PubMed ID: 15219305.
    Abstract:
    Blunt intestinal mesenteric trauma (BIMT) is a rare injury with a high morbidity and mortality. It is a diagnostic dilemma for Trauma Surgeons and Emergency Physicians. This study was undertaken to assess the role of computed tomography (CT) in BIMT. Data were analyzed from 1995 to 2002. Thirty-six cases of BIMT were identified: 16 isolated and 20 non-isolated injuries. Initial CT scan was abnormal in 74% (17 out of 23), and 83% on retrospect (2 additional cases). CT scans were abnormal (initial and repeat) in 96% (22 out of 23). The most common abnormalities were free fluid (78%), mesenteric stranding or edema (39%), bowel wall hematoma, or edema (30%). Free air was seen in 31% and oral contrast extravasation in 15% of cases of bowel perforation. CT scan findings in BIMT can be subtle and non-specific. Suspicion of BIMT warrants close observation and probably further diagnostic testing.
