Percutaneous transhepatic cholangiography and biliary drainage in pediatric liver transplant patients.

Abstract

In children with liver transplants, percutaneous transhepatic cholangiography has a critical role in evaluation and treatment of biliary complications. The purpose of this study was to evaluate the technical success and complication rates of percutaneous transhepatic cholangiography and biliary drain placement in children who underwent liver transplantation. Between January 1, 1995 and July 1, 1999, 120 pediatric percutaneous transhepatic cholangiography procedures were performed in 76 patients (34 boys, 42 girls; age range, 5 months to 18 years; mean age, 5.3 years). Patients had received left lateral segment, whole-liver, or split-liver transplant grafts. Retrospective review of all pertinent radiology studies and electronic chart review were performed. A diagnostic cholangiogram was obtained in 96% (115/120) of all procedures and drainage catheter placement was successful in 89% (88/99) of attempts. In patients with nondilated intrahepatic bile ducts, a diagnostic cholangiogram was obtained in 92% (46/50) of procedures, and drainage catheter placement was successful in 76% (19/25) of attempts. Minor complications occurred in 10.8% (13/120) of procedures and included transient hemobilia with mild drop in hematocrit level (n = 2), mild pancreatitis (n = 1), fever with bacteremia (n = 5), and fever with negative blood cultures (n = 5). Major complications occurred in 1.7% (2/120) of procedures and included sepsis (n = 1) and hemoperitoneum requiring immediate surgery (n = 1). Percutaneous transhepatic cholangiography and biliary drainage can be performed with high technical success and low complication rates in pediatric liver transplant patients, even in those with nondilated intrahepatic ducts.
