    Abstract:
    OBJECTIVE: The objective of our study was to assess the diagnostic value of CT enteroclysis compared with conventional enteroclysis in patients with Crohn's disease. SUBJECTS AND METHODS: Fifty consecutive patients (26 women, 24 men; mean age, 36.3 years; age range, 18-52 years) with histologically proven Crohn's disease underwent CT enteroclysis and conventional enteroclysis (median time interval, 21.7 days) during a symptomatic stage of their disease. Both techniques were compared with regard to diagnostic yield in assessing the presence and extent of disease. Imaging findings were compared with surgery, follow-up examinations, or both. RESULTS: CT enteroclysis and conventional enteroclysis were successfully performed in all 50 patients. Crohn's disease-associated radiographic changes were found in 44 patients (88%) using CT enteroclysis and in 42 patients (84%) using conventional enteroclysis. Significantly more Crohn's disease-associated abnormalities were diagnosed with CT enteroclysis than with enteroclysis (p < 0.01). Minimal inflammatory changes of the mucosa were diagnosed in 44 patients (88%) using CT enteroclysis and in 42 patients (84%) using enteroclysis. Both imaging methods depicted stenotic bowel segments in 34 patients (68%), and prestenotic dilatation was diagnosed in 20 patients (40%) with CT enteroclysis and in 15 (30%) with enteroclysis. Fistulas were found in 18 patients (36%) with CT enteroclysis and in eight (16%) with enteroclysis (p < 0.01). Skip lesions could be seen in 17 (34%) and three patients (6%), respectively (p < 0.01). Conglomeration of bowel loops tumors was diagnosed with CT enteroclysis in 13 patients (26%) and in three patients (6%) using conventional enteroclysis (p < 0.01). Only CT enteroclysis depicted abscesses in eight patients (16%) (p < 0.01). CONCLUSION: CT enteroclysis proved to be significantly superior to conventional enteroclysis in depicting Crohn's disease-associated intra- and extramural abnormalities. CT enteroclysis is the imaging method of choice and should replace enteroclysis in patients with Crohn's disease.
