Computed tomography of pancreatic trauma

Area of Science:

• Radiology
• Trauma Surgery
• Abdominal Imaging

Background:

• Pancreatic injuries are a significant concern in abdominal trauma.
• Accurate and timely diagnosis is crucial for effective patient management.
• Computed tomography (CT) is a primary imaging modality for evaluating abdominal trauma.

Purpose of the Study:

• To evaluate the diagnostic accuracy of CT in identifying surgically proved pancreatic injuries.
• To identify specific CT findings indicative of pancreatic trauma.

Main Methods:

• Retrospective review of over 300 CT scans of patients with abdominal trauma.
• Analysis of 13 patients with surgically confirmed pancreatic injuries.
• Correlation of CT findings with surgical outcomes.

Main Results:

• CT correctly diagnosed pancreatic injuries in 11 out of 13 patients.
• Two false positive and two false negative diagnoses occurred.
• Thickening of the left anterior renal fascia was observed in 8 of 11 correctly diagnosed cases.

Conclusions:

• CT is a valuable tool for diagnosing pancreatic trauma, though challenges exist in early post-injury scans.
• Subtle peripancreatic changes and fracture planes can be difficult to discern.
• Thickening of the left anterior renal fascia is a significant CT sign that warrants critical evaluation of the pancreas in trauma patients.
