Summary
Intravenous contrast-enhanced computed tomography (CT) tractography accurately detects peritoneal violation in anterior abdominal stab wounds (AASW). This imaging technique guides management, allowing safe serial abdominal examination for non-penetrating injuries.
Area of Science:
- Radiology
- Trauma Surgery
- Emergency Medicine
Background:
- Anterior abdominal stab wounds (AASW) require accurate assessment for peritoneal violation.
- Diagnostic laparoscopy (DL) is often used, but can lead to non-therapeutic interventions.
- Non-invasive imaging modalities are crucial for improving AASW management.
Purpose of the Study:
- To evaluate the accuracy of IV contrast-enhanced CT tractography in detecting peritoneal violation in AASW.
- To assess the impact of CT tractography findings on the clinical management algorithm for AASW.
Main Methods:
- Prospective study of 61 patients with AASW.
- Classification of injuries into penetrating, equivocal, and non-penetrating using IV contrast-enhanced CT tractography.
- Correlation of CT findings with management outcomes (DL or serial abdominal examination - SAE).
Main Results:
- CT tractography classified injuries as non-penetrating (54.1%), equivocal (14.8%), and penetrating (31.1%).
- All non-penetrating injuries were managed successfully with SAE.
- DL confirmed peritoneal violation in penetrating injuries and was negative in equivocal injuries.
- CT tractography demonstrated 100% sensitivity, specificity, and accuracy, with no missed injuries.
Conclusions:
- IV contrast-enhanced CT tractography is highly effective for evaluating AASW.
- Negative CT findings allow for safe management with SAE.
- Positive CT findings accurately indicate peritoneal violation requiring further intervention.
- Equivocal findings may be suitable for frequent SAE, potentially reducing non-therapeutic laparoscopies.
