✦ Synopsis
Duplication of the duodenum usually presents with intestinal obstruction in childhood but may undergo ulceration and bleeding. The gastro-oesophageal group of portasystemic collaterals is the most common site for bleeding in portal hypertension, but varices have occasionally been described elsewhere in the gastrointestinal tract. These 'ectopic' varices may be caused by generalized portal hypertension, when they can accompany oesophageal varices', or by isolated superior mesenteric vein (SMV) obstruction with a normal blood flow pattern in the portal and splenic veins'.
A patient is presented who had massive intestinal bleeding associated with segmental portal hypertension caused by obstruction of the SMV by a duodenal duplication.
