To the Editor: We disagree with some aspects of the studies and therapy of the 70-year-old man with diverticulitis reported by Drs. Nanda and Amini (Aug. 24 issue).1 We question the need for a barium enema, especially one performed on the same day as the computed tomography (CT). CT is the single best test for the diagnosis of diverticular inflammation. In one study,2 it revealed inflammation of pericolic fat 98 percent of the time. CT also reveals unsuspected extraluminal disease, such as an abscess, without the risk of barium peritonitis, which may result from a barium enema. We also question.
