Choledochal cysts: Similarities and differences between Asian and Western countries

Figure 1 Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography demonstrating choledochal cyst types. A: Type I choledochal cyst (CC) on endoscopic retrograde cholangiopancreatography; B: Type II CC on magnetic resonance cholangiopancreatography (MRCP); C: Type III CC on MRCP; D: Type IV CC on MRCP; E: Type V CC on MRCP. CC: Choledochal cyst; MRCP: Magnetic resonance cholangiopancreatography.

Figure 2 Magnetic resonance cholangiopancreatography and/or endoscopic retrograde cholangiopancreatography showing anomalous pancreaticobiliary junction types. A: P-C anomalous pancreaticobiliary junction (APBJ) from endoscopic retrograde cholangiopancreatography; B: Complex APBJ from intraoperative cholangiogram (IOC); C: C-P APBJ from IOC. Arrows point to junction with common channel. IOC: Intraoperative cholangiogram; APBJ: Anomalous pancreaticobiliary junction.
