[Haemosuccus pancreaticus as a rare initial manifestation of chronic pancreatitis]

Haemosuccus pancreaticus is an unfrequent but known cause of an upper gastrointestinal bleeding. Pathogenesis of spontaneous severe hemorrhage of the pancreatic duct includes chronic pancreatitis generated pseudocysts or aneurysms of the visceral arteries. We present two cases of severe spontaneous gastrointestinal bleeding as a first manifestation of chronic pancreatitis, in which the diagnosis chronic pancreatitis was not known and the patients denied any gastrointestinal symptoms in their medical history at the time of hemorrhage.
