Objective To investigate and analyze the clinical value of B-mode ultrasonography and CT in the diagnosis of patients with emergency abdominal trauma. Methods 46 ptients with abdominal trauma who were treated in the department of emergency trauma surgery of our hospital between January and August 2015 were enrolled in the study. After admission, all patients underwent routine preliminary diagnosis with B-mode ultrasonography and CT. The surgical and pathological results were taken as the golden standard to analyzed the diagnostic effects of the two imaging means. Results The surgical and pathological results showed that patients with abdominal organ injury accounted for 93.48%. There was no significant difference in accurate rates between B-mode ultrasonography and CT in the diagnosis of splenic injuries (86.36% vs 95.45%), liver damage (90.00% vs 80.00%), renal injury (100.00% vs 80.00%), pancreatic injury (60.00% vs 80.00%), small intestine and duodenal injury (66.67% vs 100.00%) and peritoneal injury (60.00% vs 80.00%) (P>0.05). Conclusion B-mode ultrasonography and CT are effective imaging methods for the clinical diagnosis of abdominal organ injury in patients with abdominal trauma. They are non-invasive, simple and effective, which can provide important reference for guiding the clinical treatment.
