title: The barium enema; evidence for proper utilization.
abstract: A group of 1,041 patients was studied in an attempt to identify symptoms, signs, or laboratory findings (disease indicators) associated with either a high or low yield of abnormal barium enemas. A specific search was undertaken for subgroups with one or more statistically significant indicators of large bowel disease. If enemas were performed only for statistically significant indicators (fever, positive stool benzidine, rectal or abdominal mass, low hematocrit) or indicators of clinical importance (weight loss, constipation, diarrhea, etc.) only 13% of examinations would be eliminated. At the same time, however, 10% of patients with gastrointestinal disease would be missed.
