Figure 3 Comparison of methods for diagnosing hilar biliary invasion of ampullary cancer in patients without biliary stents. A: Partial thickening of the bile duct wall on IDUS showed the highest diagnostic accuracy; B: Among the various combinations (imaging findings and biliary biopsy results) for diagnosing hilar biliary invasion, partial thickening of the bile duct wall on IDUS + biliary biopsy results showed the highest diagnostic accuracy. aP < 0.05. CECT: Contrast-enhanced computed tomography; ERC: Endoscopic retrograde cholangiography; IDUS: Intraductal ultrasonography; NS: Not significant.
