- “Bowel and mesenteric injuries are detected in 5% of blunt abdominal trauma patients at laparotomy and are the third most common type of injury from blunt trauma to abdominal organs. Three basic mechanisms may cause bowel and mesenteric injuries of blunt trauma: Direct force may crush the gastrointestinal tract; rapid deceleration may produce shearing force between fixed and mobile portions of the tract; and a sudden increase in intraluminal pressure may result in bursting injuries.”

Specific CT findings of bowel and mesenteric injuries include bowel wall defect, intraperitoneal and mesenteric air, intraperitoneal extraluminal contrast material, extravasation of contrast material from mesenteric vessels, and evidence of bowel infarct.”

In these regions, mobile and fixed portions of the gut are continuous and therefore are susceptible to shearing force.”
