Predicting cholecystocholedochal fistulas in patients with Mirizzi syndrome undergoing endoscopic retrograde cholangiopancreatography

Figure 3 Stricture length in common bile duct in patients with Mirizzi syndrome. A: One 2.7-cm gall bladder stone caused a cholecystocholedochal fistula. The stricture length is only 1.7 cm, which is less than the actual size of the stone; B and C: One 1.4-cm gall bladder stone compressed the common bile duct. However, the stricture of common bile duct is 3.3 cm in length. Computerized tomography after endoscopic retrograde cholangiopancreatography revealed that the plastic biliary stent was close to the stone (orange arrow).
