Summary
High-energy bullets cause more abdominal damage than shell fragments in penetrating ballistic trauma. Bullet injuries resulted in more negative laparotomies and higher mortality compared to shell fragment injuries.
Area of Science:
- Trauma Surgery
- Ballistic Injury Research
- Abdominal Trauma
Background:
- Penetrating ballistic trauma to the abdomen presents significant challenges in diagnosis and management.
- Distinguishing injury patterns and outcomes between different types of ballistic agents (e.g., bullets vs. shell fragments) is crucial for optimizing treatment strategies.
- Understanding the specific organ damage and complication rates associated with each injury type informs surgical decision-making.
Purpose of the Study:
- To retrospectively compare the extent of abdominal injury and patient outcomes between penetrating ballistic trauma caused by shell fragments and bullets.
- To analyze differences in intra-abdominal findings, organ injury patterns, associated extra-abdominal injuries, postoperative complications, and perioperative mortality between the two groups.
Main Methods:
- Retrospective analysis of 299 patients with penetrating abdominal ballistic trauma.
- Patients were divided into two groups: Group A (shell fragment injuries, n=133) and Group B (bullet injuries, n=166).
- Comparison of laparotomy findings, injured abdominal organs, extra-abdominal injuries, postoperative complications, and perioperative mortality.
Main Results:
- Group B (bullet injuries) had a significantly lower rate of negative laparotomies (5%) compared to Group A (shell fragments, 10%).
- Commonly injured organs included the colon, liver, and small bowel in both groups, with higher incidence in Group B for colon (50% vs 42%) and small bowel (41% vs 20%).
- Perioperative mortality was significantly higher in Group B (7.2%) than in Group A (2.3%), suggesting greater tissue penetration and blast effect from high-energy bullets.
Conclusions:
- High-energy bullets cause greater tissue penetration and blast effects in abdominal trauma compared to shell fragments.
- Bullet injuries are associated with a higher likelihood of intra-abdominal injury requiring surgical intervention and a higher perioperative mortality rate.
- These findings underscore the distinct injury mechanisms and outcomes associated with different ballistic agents in abdominal trauma.
