Radiographic predictors of therapeutic operative intervention after blunt abdominal trauma: the RAPTOR score

Area of Science:

• Trauma Surgery
• Diagnostic Imaging
• Abdominal Trauma

Background:

• Bowel and mesenteric injuries are infrequent complications of blunt abdominal trauma.
• Computed tomography (CT) is essential for evaluating stable trauma patients.
• Identifying predictors for operative intervention is crucial for patient management.

Purpose of the Study:

• To identify radiographic predictors of therapeutic operative intervention for mesenteric and/or bowel injuries.
• To develop a scoring system for predicting surgical necessity in blunt abdominal trauma.

Main Methods:

• Retrospective review of 151 patients with blunt abdominal trauma and bowel/mesenteric injury over 5 years.
• Analysis of admission CT scans to identify injury predictors.
• Development of the Radiographic Predictors of Therapeutic Operative Intervention (RAPTOR) score.

Main Results:

• 76% of patients underwent operative intervention; 66% had therapeutic laparotomy (TL).
• Key predictors for TL included acute arterial extravasation, bowel devascularization, and fat pad injury.
• The RAPTOR score (≥3) demonstrated 67% sensitivity and 86% positive predictive value for TL.

Conclusions:

• CT imaging is vital for assessing bowel and mesenteric injuries after blunt abdominal trauma.
• The RAPTOR score simplifies the prediction of necessary early surgical intervention.
