title: Early water-soluble contrast enema in the diagnosis of acute colonic diverticulitis.
abstract: Acute colonic diverticulitis is usually suspected by typical clinical findings supported by laboratory tests. Investigations of the colon are usually delayed 1 to 2 months until the acute situation is resolved. We studied 53 patients with an initial clinical diagnosis of acute diverticulitis by performing early water-soluble contrast enema of the colon. The initial diagnosis proved to be uncertain, as 26 patients (49%) had acute colonic diverticulitis as their final diagnosis. There were ten patients who had diverticulosis of the colon, but without radiologic signs of acute diverticulitis. Four of these patients had some other disease responsible for their symptoms. Thirteen patients had normal findings at early water-soluble contrast enema. Three colonic carcinomas and one ischaemic colitis were diagnosed. There were no complications related to the radiologic studies. We conclude that early water-soluble contrast edema of the left colon is safe and useful in investigating patients with suspected acute colonic diverticulitis. If the finding is normal, investigations can be directed elsewhere without undue delay.
