Summary
Computerized tomography (CT) is more effective than diagnostic peritoneal lavage (T&L) or intravenous pyelogram (IVP) for detecting injuries in patients with blunt abdominal trauma. CT identified injuries missed by T&L and is crucial for evaluating hematuria.
Area of Science:
- Radiology
- Trauma Surgery
- Diagnostic Imaging
Background:
- Blunt abdominal trauma poses diagnostic challenges.
- Traditional methods like T&L and IVP have limitations in sensitivity and specificity.
- Computerized tomography (CT) offers advanced imaging capabilities.
Purpose of the Study:
- To compare the diagnostic accuracy of CT with T&L and IVP in blunt abdominal trauma.
- To evaluate the utility of CT in patients with hematuria.
- To assess CT's effectiveness in identifying genitourinary (GU) abnormalities.
Main Methods:
- 103 patients with blunt abdominal trauma underwent CT scans with oral and IV contrast.
- CT was performed before T&L, after T&L, or for hematuria evaluation.
- Comparison of CT findings with T&L results and operative/angiographic findings.
Main Results:
- CT identified injuries missed by T&L in 16 of 42 patients with negative lavage and 6 of 14 with borderline lavage.
- CT detected GU abnormalities in 17 of 85 patients with hematuria, including renovascular injuries and bladder perforations.
- CT demonstrated higher sensitivity and specificity compared to T&L and IVP.
Conclusions:
- Abdominal CT is superior to T&L and IVP for diagnosing blunt abdominal trauma.
- CT is essential for evaluating patients with hematuria and identifying subtle GU injuries.
- CT imaging significantly improves the detection of intra-abdominal and GU injuries.
