Diverticula of the colon are the most common cause of lower gastrointestinal bleeding in adults. In cases of persistent loss of blood or severe acute hemorrhage, treatment is required. However, if these modern intervention techniques are inadequate, surgical resection of the colon may be required. Diverticular bleeding often concerns patients with a high surgical risk, so a less invasive treatment is preferable. A forgotten but excellent treatment, namely that of the obsolete barium contrast enema to staunch diverticular bleeding, is the focus of this case series. We describe 3 patients who were successfully treated with barium enema.
