Figure 5.22. Adhesive small-bowel obstruction with ischemia. (A) Supine film of the abdomen demonstrates residual contrast medium in dilated small-bowel loops from a recent CT series. Pneumatosis of one loop of bowel in the left midabdomen is indicative of ischemia. (B) Section from a CT scan on the same patient better demonstrates the air collections in the nondependent portions of the small-bowel wall. The obstruction and ischemia were secondary to adhesions.
