Abstract
The value of the double contrast technique for the detection of early changes of colitis and for the differentiation between ulcerative and granulomatous colitis was illustrated. Fifty consecutive patients with radiologically-diagnosed nonspecific colitis were included and the radiographs, endoscopic and pathologic reports and photographs were reviewed. On radiological grounds ulcerative colitis was diagnosed in 23 patients and granulomatous colitis in 27 patients. There were no radiologically indeterminate cases. Follow-up information was obtained by colectomy in 9 patients, colonoscopy in 9 patients and sigmoidoscopy in the remainder. In no case did the endoscopic or pathologic diagnosis conflict with the radiological diagnosis. With the double contrast technique very fine mucosal detail was seen including features such as granular mucosa, aphthoid ulcers and discontinuous disease which were not demonstrable by the conventional single contrast Ba enema. This detailed mapping of the nature and extent of disease facilitated the differential diagnosis between ulcerative and granulomatous colitis.
