Traumatic abdominal wall injuries-a primer for radiologists

Area of Science:

• Trauma Surgery
• Diagnostic Radiology
• Abdominal Imaging

Background:

• Traumatic abdominal wall injuries affect approximately 9% of blunt trauma patients.
• Traumatic abdominal wall hernias, the most severe form, occur in <1.5% of blunt abdominal trauma cases.
• Concurrent intra-abdominal injuries are common and increase morbidity/mortality.

Purpose of the Study:

• To highlight the importance of radiologist recognition of abdominal wall injuries on CT.
• To emphasize the need for early diagnosis and surgical management of these injuries.
• To underscore the association between abdominal wall defects and intra-abdominal trauma.

Main Methods:

• Review of clinical and radiological presentations of traumatic abdominal wall injuries.
• Analysis of computed tomography (CT) findings in blunt trauma patients.
• Correlation of abdominal wall injuries with concurrent intra-abdominal pathologies.

Main Results:

• Abdominal wall injuries are often identified on admission CT scans.
• Associated intra-abdominal injuries can be subtle and may distract from the primary diagnosis.
• Prompt identification is essential for appropriate surgical planning and patient triage.

Conclusions:

• Radiologists must be knowledgeable about the spectrum of abdominal wall injuries and associated findings.
• Early diagnosis of traumatic abdominal wall injuries and concurrent intra-abdominal injuries is critical.
• Failure to manage these injuries can lead to delayed bowel incarceration and strangulation.
