Abstract

膵・胆管合流異常症例において,圧勾配により膵液が胆管内に逆流することは良く知られているが,画像上それを証明することは難しい.膵・胆管合流異常症例において,副乳頭から膵管を造影し,主膵管から胆管への造影剤の逆流を観察したので報告する.主膵管内の造影剤は主乳頭から十二指腸内へ流出しないまま,共通管を介して中部胆管まで逆流を認めた.膵・胆管合流異常における膵液の胆管内逆流は,容易に起こりうることが推察された.

Pancreaticobiliary maljunction is a congenital anomaly with a union of the pancreatic and biliary ducts that is located outside the duodenal wall. Pancreatic juice refluxes into the bile duct because the action of the sphincter muscle (Oddi) does not functionally affect the union. We proved roentogenographically this regurgitation by pancreatography via the minor duodenal papilla. Contrast medium injected into the accessory pancreatic duct from the minor duodenal papilla, moved through the main pancreatic duct into the bile duct. The middle and inferior bile duct was opacified, though the contrast was not excreted into the duodenum via the major duodenal papi lla. Pancreatography via the major duodenal papilla situated in the horizontal portion of the duodenum revealed the pancreaticobiliary maljunction with 2 cm-common channel in length.<BR>It is suggested that regurgitation of the pancreatic juice into the bile duct easily occurs in pancreaticobiliary maljunction.
