Intestinal obstruction role of CT.

CT has significantly advanced the evaluation of small and large bowel obstruction, especially in the acute situation where high-grade or possibly strangulating obstruction is being encountered. Any physician involved in evaluating patients with bowel distention and abdominal pain where obstruction becomes a distinct diagnostic possibility should be aware of the attributes and limitations of this modality to provide the best patient care. New technological advances will hopefully limit radiation exposure and provide even more definitive information in the diagnosis of bowel obstruction.
