Small bowel and colon injuries are most commonly caused by what type of trauma?

• A. Aneurysm rupture
• B. Blunt trauma
• C. Penetrating trauma
• D. Thermal injury

Answer: (C)

Penetrating trauma is the mechanism most likely to cause injuries to the small bowel and colon because direct entry of a blade or bullet breaches the abdominal wall and perforates hollow viscera, leading to obvious perforations and contamination. Blunt trauma can damage these organs too, but it more often causes mesenteric tears, contusions, or delayed injury rather than immediate, direct perforation. Aneurysm rupture and thermal injury aren’t typical mechanisms for hollow-viscus trauma in this context. Thus penetrating trauma best explains why the small bowel and colon are injured most commonly.
