Abstract

PurposeTo evaluate efficacy and safety of transjugular liver biopsy (TJLB) via the left hepatic vein in patients with left lobe–only liver transplants (LLOTs). Materials and MethodsRetrospective review revealed 43 TJLBs performed in 26 patients with LLOTs (mean age 51.3 y; range, 18–73 y) between January 2009 and June 2016 at a single institution. A comparison group of 44 randomly selected TJLBs performed in 37 orthotopic whole liver transplant (OWLT) recipients (mean age 57.6 y; range, 35–74 y) during the same time period was evaluated. Patient demographics, type and age of transplant, technical success, adequacy of samples, number of portal tracts obtained, pathologic diagnosis, and complication rate were reviewed. ResultsTechnical success was achieved in 98% (42/43) of LLOT procedures. TJLB failed in 1 patient with LLOT, in whom no patent hepatic veins were identified. Technical success was achieved in 100% (44/44) in the OWLT group. Mean (SD) number of needle passes was 4.12 (1.25) in the LLOT group vs 3.95 (1.28) in the OWLT group (P = .54). Mean (SD) specimen length was 1.16 (0.75) cm in the LLOT group vs 1.19 (0.58) cm in the OWLT group (P = .78). Mean (SD) number of portal tracts obtained in the LLOT group was 10.7 (5.26) vs 12.3 (4.68) in the OWLT group (P = .17). No major complications were observed in either group. ConclusionsTJLB in adult patients with LLOTs appears safe and feasible, with favorable rates of technical success and adequacy of sampling.
