title: [Timely colonoscopy leads to faster identification of bleeding diverticulum].
abstract: We conducted a retrospective study of the efficacy of a polyethylene glycol purge before colonoscopic examination in 110 patients with colonic diverticular bleeding. The patients' data were assessed for the timing of colonoscopy and the methods used to stop bleeding. The rate at which bleeding diverticula were identified was markedly higher when a purge was used than when it was not (28.2% vs. 12.0%, p=0.11). In addition, the identification rate was significantly higher when colonoscopic examination was performed within 18 hours of the final hematochezia than when it was performed after 18 hours (40.5% vs. 10.5%, p<0.01). These findings suggest that patients with diverticular bleeding should undergo colonoscopy following an orally administered colonic purge, providing their condition permits. Furthermore, colonoscopy should be performed within 18 hours of the final hematochezia in order to improve identification of the bleeding diverticulum.
