title: [Ischemic ulcer of stomach and duodenum: an unusual cause of a common disease].
abstract: Ischemia is a rare cause of gastric and duodenal ulcers. For the present study clinical and anatomo-pathologic data from cases published so far and from twelve own patients with ischemic ulcers have been investigated. Histopathology leads to the diagnosis of an ischemic cause with great accuracy. Our results show that ischemic ulcers occur often at gastric sites unusual for a peptic ulcer, and in some cases they look macroscopically different from peptic ulcers. The most common symptom was severe gastrointestinal bleeding. Pain, typical for peptic ulcers, has only rarely been noted by patients. Lethal courses were usually due to gastrointestinal bleeding resistant to therapy. Resection of the involved gastric or duodenal segment or surgical or angiologic reconstruction of the vessels respectively are promising therapeutic means. Without therapeutic intervention very different courses have been observed, ranging from spontaneous healing to fatal gastrointestinal bleeding. The benefit of inhibitors of acid secretion is so far unclear.
