Biliary complications in liver transplantation

Area of Science:

• Hepatology
• Transplant Surgery
• Gastroenterology

Background:

• Biliary complications (BC) are a significant source of morbidity following liver transplantation (LT).
• Understanding the incidence, risk factors, and management strategies for BC is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze the incidence, risk factors, and management of biliary tract complications in liver transplant recipients.
• To evaluate the effectiveness of different biliary reconstruction techniques in preventing BC.

Main Methods:

• A retrospective analysis of 118 orthotopic liver transplants performed between 1992 and 2000.
• Biliary reconstruction methods included choledochocholedochostomy with/without T tube and choledochojejunostomy.
• Biliary complications were categorized as stenosis, leaks, or cholangitis.

Main Results:

• BC occurred in 27.9% of liver transplant recipients.
• The highest incidence of BC was observed with choledochojejunostomy (57.1%) and choledochocholedochostomy with T tube (44.8%) reconstructions.
• Stenosis was the most frequent complication (20 patients), followed by leaks (13 patients) and cholangitis (10 patients).
• Endoscopic therapy was the primary treatment for 17 patients, while 12 required surgical intervention.

Conclusions:

• Biliary complications remain a common issue post-liver transplant, with rates remaining constant in recent years.
• Technical failure and local ischemia are identified as primary causes of BC.
• End-to-end choledochocholedochostomy without a T tube demonstrated the lowest BC incidence and is recommended as the preferred method.
• Early and aggressive management, often involving endoscopic procedures, can significantly reduce mortality associated with BC.
