Abstract

BACKGROUND:

Biliary stones after liver transplantation (LT) rarely occur but a focus on those complications and their treatment is needed.

PATIENTS AND METHODS:

In total, 390 adult patients who underwent an LT from July 2004 to July 2014 entered the study. Biliary complications and notably biliary stones after LT were identified.

RESULTS:

In total, 365 LT were analyzed. Biliary stones were identified in 14 patients (3.8%). Predictive factors for the onset of biliary stones after LT were hepatocellular diseases (P = .038; OR = 9.7) and biliary stenosis (P = .000; OR = 11.9). Treatments consisted of percutaneous transhepatic procedures (4 patients), endoscopic retrograde procedures (9 patients), and in open surgery (1 case); in 2 cases, due to a failure of previous treatments, holmium intraductal laser lithotripsy (HILL) was used: the first patient, a 35-year-old woman developed multiple intrahepatic biliary stones after LT. Percutaneous transhepatic cholangiography (PTC) was ineffective and a HILL was performed, clearing the right common bile duct but leaving residual stones in the left duct. The patient underwent a retransplantation due to recurrent hepatitis C virus infection but died 3 months later because of graft failure. The second patient, a 42-year-old 14 years after retransplantation, developed biliary sludge and stones; after several attempts with PTC and endoscopic retrograde cholangiopancreatography, a HILL was performed. All stones except one big one were treated. The patient is alive and well.

CONCLUSIONS:

When usual treatments are unsuccessful and biliary stones are large, their fragmentation and treatment could be done with HILL, a promising procedure after LT.
