title: Fistula between duodenum and portal vein caused by peptic ulcer disease and complicated by hemorrhage and portal vein thrombosis.
abstract: We document a patient with a penetrating peptic ulcer of the first part of the duodenum, that extended into the main portal vein forming a fistula. This is the first reported case of a duodenoportal fistula secondary to peptic ulcer disease. The fistula was complicated by massive gastrointestinal hemorrhage, extra- and intrahepatic portal vein thrombosis, hepatic parenchymal infarction, and intrahepatic portal vein foreign body granulomas containing vegetable matter.
