SUMMARY BackgroundBleeding recurrence rate after spontaneous haemostasis of colonic diverticular haemorrhage varies in the literature, and a small minority of patients will require endoscopic, radiological or surgical intervention.

Stool consistency and low stimulation intensity have been identified as predictive factors for the short-term outcome of SNS.

The prevalence of colonic diverticula increased from < 10% in adults under 40 years of age to about 75% in those over 75 years of age. Of these patients, nearly one-third presented with right-sided involvement. Right-sided localization was associated with a significant risk of bleeding, which was independent of the patients' age.
