Summary
Biliary sludge, a rare complication after liver transplant, can form obstructive casts. This case highlights successful treatment using surgery, interventional radiology, and endoscopy.
Area of Science:
- Hepatobiliary Surgery
- Transplantation Medicine
- Gastroenterology
Background:
- Orthotopic liver transplantation (OLT) has advanced, reducing complications.
- Biliary sludge formation, especially without common bile duct obstruction, is now rare post-OLT.
- Modern surgical techniques and preservation methods minimize biliary issues.
Observation:
- An 18-year-old female recipient developed severe biliary sludge post-OLT.
- The sludge formed firm casts obstructing both extrahepatic and intrahepatic bile ducts.
- This led to significant obstruction and cholangitis, requiring intervention.
Findings:
- Successful treatment involved a multi-modal approach: operative intervention, interventional radiology for strictures, and postoperative choledochofiberscopy.
- Choledochofiberscopy effectively removed retained biliary casts.
- Cold ischemic time during transplantation was identified as a potential key factor in sludge pathogenesis.
Implications:
- This case underscores the importance of vigilance for rare biliary complications even with modern OLT techniques.
- Multi-modal treatment strategies can effectively manage complex biliary sludge cast formation.
- Further research into the role of cold ischemic damage in biliary complications post-transplant is warranted.
