Endoscopic Biliary Intervention Following Orthotopic Liver Transplantation

Krishnaraj Mahendraraj, MD, Guillermo Medrano Del Rosal, MD, Michelle Kruse, BS. Lincoln Medical Center

Introduction: Biliary tract complications that require endoscopic decompression represent a greater challenge after liver transplantation than in non transplanted patients. Immunosuppressive therapy predisposes patients to a greater risk of infections and poor healing process. This comparative study analyzes risk factors and outcomes in liver transplant patients with biliary pathology that requires endoscopic intervention.

Methods: Information obtained from National Inpatient Sample database over a 15-year period (2001-2011). This included a total 10,252 patients who underwent liver transplantation, 581(6%) if these patients experienced biliary system complications. Univariate and multivariate was obtained via Statistical Package for the Social Sciences (SPSS). Statistical significance was accepted for p-value < 0.05.

Results: A total of 581 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) after hepatic transplantation, 80% of them had sphincterotomy and stent placement. These were mostly seen in men (64.5%), caucasians (69.8%) with a mean age of 52 years, however these results were similar to the no intervention group. These patients were diabetic with chronic complications (4.9% vs 2.9%) and had congestive heart failure (3.8% vs 2.4%). Choledochoenterostomy was a protective factor for having biliary pathology requiring endoscopic intervention. Biliary complications that required intervention were; choledocholithiasis (18.8% vs 9.5%), cholangitis (36.7% vs 7.5%), biliary stricture (36.7% vs 3.8%), biliary leak (0.7% vs 0.1%). Length of stay > 1 week was greater in the biliary intervention group (98.3% vs 77.6%). Significant complications seen in patients requiring intervention were; sepsis (23.2% vs 11.8%), urinary tract infections (12.6% vs 8.5%), acute renal failure (39.9% vs 31.1%), peritonitis or intra abdominal abscess (11.4% vs 6.0%), wound infection (11.7% vs 6.0%) and acute rejection (46.1% vs 18.4%). In-hospital mortality was significantly higher for patients with biliary pathology requiring endoscopic intervention (7.2% vs 5.3%).

Conclusion: Biliary system pathologies requiring endoscopic intervention had life threatening complications and thus mortality rate on the same admission. Interestingly, choledochoenterostomy decreased the risk of biliary tract pathology that required instrumentation.
