Management of diverticular hemorrhage.

Diverticular hemorrhage is the most common cause of lower gastrointestinal bleeding in Westernized cultures. Fortunately, the majority of diverticular bleeds will spontaneously resolve; however, 20% of patients will require therapeutic interventions to obtain hemostasis.

Superior mesenteric artery syndrome in the modern trauma patient.

In 1861, von Rokitansky described obstruction of the third part of the duodenum by external compression of the duodenum by the superior mesenteric artery (SMA). In 1926, this entity was furthermore described by Wilke in his presentation of 75 patients with "chronic duodenal compression". In 1968, Mansberger used angiography to define anatomical measurements as the diagnostic criteria for this condition.
