The incidence of colonic diverticular bleeding (CDB) is gradually increasing, because of an aging society and increasing usage of anticoagulants and nonsteroidal anti-inflammatory drugs (NSAIDs). Herein, we examined the present status, including the characteristics, diagnosis, therapy and prognosis of CDB. In this study, we enrolled 501 patients from 10 facilities who filled out our questionnaire. Of the 501, 304 (60.1％) were 70 years of age or over, and 320 (63.9％) were male；244 patients (48.7％)had hypertension, and 222 patients (44.3％) were taking anticoagulants or NSAIDs. Bleeding lesions were definitively diagnosed in 278 patients (55.8％) and mostly 164 lesions (32.7％) in the ascending colon, and the lesions were most frequently detected in the ascending colon (164 lesions [32.7％]). The diagnosis was made by colonoscopy in 426 patients (85.0％) and by computed tomography in 146 patients (29.1％). In all, 198 patients (39.8％) required hemostasis, and endoscopic clipping was performed in the majority. Difficulty in establishing hemostasis and rebleeding were encountered in 16.7％ of patients (33/198 patients). Some patients were treated by interventional radiology (IVR) techniques or surgery.
