AAST Bowel Injury Scale

AASTBowel Injury Scale

Highest Finding (Imaging/OR)

Bowel Injury Grading

Select the highest radiologic or operative finding to determine the AAST severity grade.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Blunt abdominal trauma with suspected hollow viscus injury (e.g., seatbelt sign, high-speed MVC)

Penetrating abdominal trauma (stab wounds, gunshot wounds) involving bowel trajectory

Unexplained peritonitis following trauma

Free intraperitoneal air or fluid without solid organ injury on CT imaging

Intraoperative identification of bowel injury requiring classification

Trauma registry documentation and prognostic stratification

Clinical Utility

Standardizes description of bowel injuries across trauma systems

Guides operative vs non-operative management decisions

Helps determine need for resection vs primary repair vs diversion

Predicts morbidity such as leak, abscess, and sepsis

Facilitates communication between trauma surgeons and multidisciplinary teams

Limitations

Does not incorporate degree of contamination or time to surgery

Does not directly account for patient physiology or shock state

Less predictive in polytrauma where competing injuries dominate outcomes

Inter-observer variability in CT-based detection of bowel injury

Contraindications / Exclusions

Non-traumatic bowel perforation (e.g., malignancy, ulcer)

Isolated mesenteric injuries without bowel wall involvement

Postoperative or iatrogenic bowel injuries
