Intestinal Pneumatosis Diagnosis and Management

Diagnostic Imaging

The World Journal of Emergency Surgery recommends CT scan as the most sensitive imaging modality for detecting intestinal pneumatosis, clearly showing gas within the bowel wall rather than in the lumen 1, 2
CT scans can show pneumatosis as gas tracking within the bowel wall, which may be linear or bubble-like in appearance 2
Ultrasound may show pneumatosis as echogenic reflections within the bowel wall, though it is less sensitive than CT 3
Plain radiographs can sometimes detect pneumatosis but are less sensitive than CT for distinguishing between intraluminal and extraluminal air 1

Intestinal pneumatosis can occur as a result of colonoscopy, where mucosal injury and intraluminal pressure may dissect air inside the bowel wall 1
Air can dissect into the bowel wall through mucosal defects or increased intraluminal pressure 1, 2

The American College of Surgeons and other medical societies suggest that the clinical management of intestinal pneumatosis depends on the underlying cause and the patient's clinical status, as outlined in various clinical guidelines 4
CT findings of pneumatosis with distant intraperitoneal free air often indicate perforation requiring surgical exploration 4
Laboratory tests including white blood cell count and C-reactive protein should be obtained to assess for inflammatory markers that might indicate infection or ischemia 1, 5
