Abstract
Background and Aims
To prospectively evaluate the role of contrast-enhanced computed tomography (CE-CT) in the detection of colonic diverticular bleeding (CDB).
Patients and Methods
Consecutive patients who presented with hematochezia and were clinically suspected of CDB were prospectively enrolled. Those who could undergo both CE-CT and total colonoscopy, and who were finally diagnosed as CDB, were included in the analysis.
Results
Fifty-two cases were finally included in the analysis. The detection rate of CDB by CT was 15.4 % (8/52). Univariate analysis showed that the interval from the latest episode of hematochezia to the performance of CT and the presence of a past history of CDB were contributing factors for detection. The interval was 1.6 ± 4.6 h (mean ± SD) in patients detected by CT, and 3.4 ± 3.2 h in those without detection. The detection rate of CDB by total colonoscopy was 38.5 % (20/52). The overall detection rate was 46.2 % (24/52), which was superior to what CT or colonoscopy alone achieved.
Conclusions
CE-CT may play a complementary role to colonoscopy in patients with suspected CDB, but is not recommended for all cases due to its low detection rate. Patients who can be examined within 2 h of last hematochezia would be candidates for urgent CT.
