Table 1.
Demographic and clinical characteristics of OLT patients during the two periods.
Figure 1.
Algorithm for the diagnosis and treatment of ITBLs after OLT in the control group.
ERCP, endoscopic retrograde cholangio-pancreatography; ITBLs, ischemic-type biliary lesion; MRCP, magnetic resonance cholangiopancreatography; OLT, orthotopic liver transplantation; PTCD, percutaneous transhepatic cholangiodrainage.
Figure 2.
Algorithm for the diagnosis and treatment of ITBLs after OLT in the EDIM group.
CEUS, contrast-enhanced ultrasonography; EDIM, early diagnosis and intervention mode; ERCP, endoscopic retrograde cholangio-pancreatography; ITBLs, ischemic-type biliary lesion; MRCP, magnetic resonance cholangiopancreatography; OLT, orthotopic liver transplantation; PTCD, percutaneous transhepatic cholangiodrainage.
Figure 3.
Ultrasound image of the hilar bile duct in a patient without ITBLs.
B: Regular ultrasound image showing a thickened hilar bile duct wall with a high echogenicity (arrow) and an obscure lumen. A: Arterial stage of CEUS showing high enhancement of the bile duct (arrow) and a clear lumen. CEUS: contrast-enhanced ultrasound; OLT: orthotopic liver transplantation.
Figure 4.
Ultrasound image of the hilar bile duct in a patient with ITBLs.
B: Regular ultrasound image showing a thickened hilar bile duct wall with equal echogenicity (arrow) and an obscure lumen. A: Arterial stage of CEUS showing low enhancement in the bile duct wall (arrow) and a clear lumen.
Figure 5.
Survival times of liver grafts in the two groups.
The 1- and 3-year graft survival rates were 78.4% and 53.2% in the control group and 92.9% and 78.6% in the EDIM group (P = 0.008).
