There is a complex interplay between primary injury, particularly major abdominal injury in the multi-system trauma patient, and secondary injury, which relate to patient physiology, decision making and surgical technique. Analysis of outcomes is further confounded by the variety of surgical techniques used. The challenge is to match the correct operation, for a critically injured patient, with the patient's physiology. Excellence in general surgery does not equate with excellence in trauma surgery, and a clear understanding of damage control is essential.
