Hemobilia caused by pancreatic disease is very rare. The most common cause is a splenic artery pseudoaneurysm caused by acute and chronic inflammation of the pancreas. We experienced a case regarding as hemobilia as a complication of chronic relapsing pancreatitis in a 14 year-old boy. He was admitted with chief complaints of abdominal pain and hematemesis. Two years prior to admission, intermittent attacks of abdominal pain and vomiting began to develop. Recently he suffered a weight loss of 7.8kg due to poor oral intake but regain his usual weight after management by one month of total parenteral nutrition. On the day of admission abrupt onset of abdominal pain and massive hematermesis brought him to the emergency room of our hospital, and the area of active bleeding was on the 2 nd portion of duodenum proven by endoscopic examination. Bleeding control was failed with conservative management including blood transfusion, so whipple's operation was done on the 4 th day of admission. Ffter then bleeding was controlled, but he died of sepsis and cerebral infartion on the 20 th postoperative day.
