Figure 3. Endoscopic retrograde cholangiopancreatography (ERCP) findings 1 week after onset. ERCP images from anterior in chronological order of contrast agent spreading showing multiple, non-continuous, smooth stenoses at the upper common bile duct (A and B, white arrow), common hepatic duct (C, yellow arrow), and right posterior sectoral duct root (D, pink arrow). A lightly stained remnant cystic duct (C, pink arrow head) and right anterior sectoral duct (D, yellow arrow head) are also shown. Clips on the cystic duct at laparoscopic cholecystectomy about 1 year earlier are shown (A, white arrow head). ERCP stereo image from anterior when the contrast agent has spread sufficiently (E).
