Blunt trauma to the abdomen.
There is general agreement that physical examination alone is inadequate for abdominal evaluation in the multiply injured blunt trauma patient; but controversy exists regarding the preferred method of detecting intraabdominal injuries requiring celiotomy. Both peritoneal lavage and the newer computed tomography imaging techniques have advantages and disadvantages. Direct comparisons of the two techniques have not determined a preferred method. When used as complementary rather than competitive studies, diagnostic peritoneal lavage and computed tomography imaging provide more information than either test alone.
