Preoperative cholangioscopic identification of traumatic type IVa choledochal cyst perforation after motor vehicle collision: A case report

Figure 4 Cholecystostomy cholangiogram showing common bile duct extravasation. Fluoroscopic images obtained via injection of contrast through percutaneously placed cholecystostomy tube. A: Early-phase image showing opacification of the gallbladder and proximal biliary tree, confirming the appropriate position of the tube; B: Progressive-phase image obtained with continued contrast injection, demonstrating extravasation of the contrast into an irregular, poorly marginated collection consistent with perforation of the bile duct and active bile leak.
