The patient was a 62-year-old woman with a history of severe acute pancreatitis complicated by walled-off necrosis (WON), who developed obstructive jaundice during the recovery phase from WON. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) revealed the complete obstruction of the distal bile duct, and endoscopic ultrasonography (EUS) revealed thickening of the duct wall, with a uniform distribution, and a relatively well-preserved layered structure. A cyto-pathological examination using ERCP showed no malignancy. The underlying etiology of this case may have been the formation of a cicatricial stricture during the resolution of WON, in addition to fibrosis caused by the spreading of inflammation from pancreatitis.
