Intrahepatic biliary lesions after orthotopic liver transplantation

Intrahepatic biliary lesions (IBL) are rare (2–9 %) after orthotopic liver transplantation (OLT). The aim was to evaluate the incidence, etiology and outcome. In nine years, a total 532 OLTs were performed in 481 patients. Twenty-four patients developed IBL. Eight were due to HAT, seven to ABOI, three to CDR and six to PI. The time until diagnosis of HAT is longest in patients (14 ± 6) with IBL. ABOI is another cause of IBL. CDR is a rare cause of IBL, however when it takes place, patients must undergo Rtx. Finally, PI is a relevant cause of IBL. In order to suppress the incidence of IBL we should consider 1) the systematic use of Doppler-Ultrasound; 2) emergency reoperation of patients with HAT, 3) avoid ABOI in OLT; 4) Rtx in cases of CDR, and 5) OLT should still be performed as an emergency procedure.
