Hemosuccus pancreaticus: a rare cause of gastrointestinal bleeding

BACKGROUND Hemosuccus pancreaticus (HP) is defined as upper gastrointestinal (GI) hemorrhage from the papilla of Vater via the pancreatic duct and is a rare cause of digestive bleeding. DATA SOURCE A PubMed search of relevant articles published from January 1967 to September 2011 was performed to identify current information about HP in terms of its etiology, pathophysiology, clinical presentation, diagnosis and management. RESULTS A variety of etiological factors, most commonly chronic pancreatitis but also tumors and vascular diseases, can lead to this condition. Appropriate endoscopic or radiologic procedures should be chosen to establish a precise diagnosis for patients, especially those with a known history of pancreatic disorders, who present with abdominal pain, GI hemorrhage and hyperamylasemia. There are two main therapeutic options for this condition: angiographic embolotherapy and surgery. Both treatments can stop bleeding, but angiographic embolotherapy is the treatment of choice for stable patients. Recently, new and less invasive treatments have emerged to treat this condition. CONCLUSIONS Because of its rarity and broad spectrum of causes, HP is difficult to diagnose accurately. However, appropriate endoscopic and radiologic procedures are extremely helpful for establishing a correct diagnosis. Both angiographic embolotherapy and surgery are reliable treatment options for this condition, and transcatheter intervention is the treatment of choice for clinically stable patients. Additional innovative treatments have emerged, but their effectiveness and safety must be confirmed.
