Bleeding due to esophageal diverticula is very rare. A case of esophageal intramural pseudodiverticulosis with bleeding was reported. Zenker's diverticulum is also an unusual site for gastrointestinal hemorrhage, and only a few cases have been reported. Duodenal diverticula are usually asymptomatic but may induce hemorrhage on rare occasions. Diverticula of the small intestine are rare clinical entities, and they are acquired lesions which are considered to be false diverticula. 80 % of them are located in the jejunum and their rate of bleeding is estimated at 4~5 %. The colon is the most vulnerable site of diverticula and prevalence increases with age. In Western societies, diverticula occur mainly in the distal colon, which is in contrast to Asian countries in which proximal involvement seems more prevalent. Severe hemorrhage has been reported to occur in 3 to 5 % of patients. As for endoscopic therapy for diverticular hemorrhage, hemostasis is usually carried out using a hemoclip with a hood device.
