Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding that usually presents with melena and abdominal pain. It is defined as a hemorrhage from the ampulla of Vater passing through the main pancreatic duct toward the second portion of the duodenum. Imaging is usually required to establish a diagnosis, and angiography continues to be the gold standard for both treatment and diagnosis. In some instances where bleeding is uncontrolled or if the patient is unstable, surgery may be required. Physicians should have a high index of suspicion, especially in patients with a history of chronic pancreatitis, as this diagnosis is associated with a very high mortality rate if left untreated. We report a case of a 67-year-old male with a known history of chronic pancreatitis and pancreatic pseudocyst who presented with melena and right upper quadrant abdominal pain and was found to have hemosuccus pancreaticus secondary to a gastroduodenal artery bleed. He underwent successful angiographic embolization and was discharged home after ensuring resolution of bleed and improvement in symptoms.
