Objective To investigate the value of spiral CT in enteral and mesenteric injury diagnosing and localizing caused by abdominal traumatic emergency,by the means of analyzing and comparing the preoperative CT report to X-ray and b-ultrasound reports. Methods 65 cases of confirmed enteral or mesenteric injury were recruited to explore their preoperative CT、X-ray and b-ultrasound features.Statistical analysis was conducted to calculate and compare the rate of sensitivity of 3 different test in diagnosing enteral and mesenteric injury. Results The accuracy of CT in diagnosing enteral and mesenteric injury were better than X-ray and b-ultrasound,the differences were statistical significance(P=0.012,P<0.001),and the CT features can help to localize the injury position. Conclusion Spiral CT scans have value in diagnosing enteral and mesenteric injury.
