Figure 8a.

Bowel perforation in a 29-year-old man with a penetrating stab wound by a knife. Axial CT image of the abdomen and pelvis (a) and sagittal reconstruction from CT (b) demonstrate the knife penetrating the mesentery and bowel. There is no question whether bowel or mesenteric trauma exists, even in the absence of free air. The bowel perforation was confirmed at laparotomy.
