Hepatobiliary scintigraphy for detecting biliary strictures after living donor liver transplantation

Figure 1 Hepatic iminodiacetic acid scan suggested normal graft function based on the normal hepatic uptake and normal excretion into the bile duct and bowel (A-C). However, the cholangiogram (D) obtained by endoscopic retrograde cholangiopancreatography showed a tight stricture (black arrow) at the anastomosis site.

Figure 2 Hepatobiliary scintigraphy showed decreased hepatic uptake and normal excretion within 60 min, which suggested parenchymal dysfunction of the graft (A-C). However, the cholangiogram (D) revealed a significant anastomotic stricture (black arrow).

Figure 3 By Hepatic iminodiacetic acid scan, no bowel activity was noted after 19 h (A-C). Based on this finding, endoscopic retrograde cholangiopancreatography was performed (D), and a localized anastomotic stricture (black arrow) was demonstrated.

Figure 4 Hepatobiliary scintigraphy showed no clearance of the radiotracer into the bowel on the 24-h image (A-C), therefore, biliary obstruction was strongly suggested. However, no significant stricture was found on the cholangiogram (D).
