다국어 초록 (Multilingual Abstract)

Background: Ansa pancreatica is a rare type of pancreatic duct variation. In ansa pancreatica, main pancreatic duct meet duodenum by oblique angle that may hinder drainage of pancreatic juice. Up to now, the relationship of ansa pancreatica and acute idiopathic pancreatitis is unclear. (1) Case Report: We report a case of a 15-year-old female patient who have ansa pancreatica and acute pancreatitis. When she arrived our hospital, she had severe abdominal pain which was caused by acute pancreatitis. ERCP showed diffuse dilated main pancreatic duct, two focal stricture was noticed at the body and head portion and the communication between minor pancreatic duct in shape of loop-like pathway to major duct on the proximal portion of stricture site, which is correspond to ansa pancreatica. We treated acute pancreatitis by using endoscopic removal of protein plug that allow passage of pancratic juice fi ow. Conclusion: In ansa pancreatica, the mechanism or relationship between acute idiopathic pancreatitis is unclear. Idiopathic pancreatitis may be often caused by pancreatic juice drainage disturbance that is due to anatomical variation of main pancreatic duct. (2) By decompression of main pancreatic duct, we treated acute pancreatitis that may be caused by ansa pancreatica. It is the fi rst case that clarify the hypothesis of acute idiopathic pancreatitis with ansa pancreatica. But further studies should be needed to back up this mechanism. Reference 1.
