Background/aimsColonic diverticular bleeding (CDB) is a common cause of acute lower gastrointestinal bleeding. Patients with CDB are at increased risk for recurrence. Here, we aimed to evaluate the clinical course of patients with CDB and identify risk factors for recurrent CDB (rCDB).MethodsWe included patients who were hospitalized at a single tertiary center for management of CDB between January 2005 and March 2020. A Cox proportional hazards regression analysis was performed to evaluate the risk factors of patients with rCDB as follows: model 1 adjusted by age, Charlson comorbidity index (CCI), and presence of bilateral colon diverticula; model 2 adjusted by age, CCI, and presence of left side colon diverticula; model 3 adjusted by age, CCI, and presence of sigmoid colon diverticula.ResultsAmong 219 patients (mean age, 68.0 years; 55 females), 56 and 163 had definite and presumptive CDB, respectively. During the median period of 506 days, 62 patients (28.3%) experienced rCDB. CCI score ≥ 4 was independently associated with rCDB in models 1, 2 and 3 (all p |
