Bile duct strictures after liver transplantation

Area of Science:

• Hepatology
• Transplant Surgery
• Gastroenterology

Background:

• Biliary complications are a major cause of morbidity and mortality following liver transplantation.
• Evolving transplant procedures like living donation and donation after cardiac death alter the landscape of biliary complications.

Purpose of the Study:

• To review recent advancements in the understanding, prevention, and management of biliary complications, specifically biliary strictures, after liver transplantation.
• To highlight how changes in donation types and pediatric procedures impact biliary complication incidence and causes.

Main Methods:

• Review of recent literature focusing on biliary complications post-liver transplantation.
• Analysis of advancements in imaging, interventional radiology, and endoscopic management.
• Evaluation of novel endoscopic techniques and adjunct therapies.

Main Results:

• Improved endoscopic treatments for post-liver transplant biliary complications, including new stenting devices and routine microbial analysis.
• Steroids are effective in preventing post-ERCP pancreatitis; Cytomegalovirus and Hepatitis C are key etiological factors.
• Donation after cardiac death organs can yield comparable biliary complication rates to brain death donors with appropriate management; risk-adapted biliary drainage is supported.

Conclusions:

• Ongoing research into etiology, prevention, and treatment of biliary strictures is crucial.
• Biliary complications significantly impact patient survival and graft success after liver transplantation.
