Simultaneous splenectomy during liver transplantation augments anti-viral therapy in patients infected with hepatitis C virus

BackgroundSimultaneous splenectomy in liver transplantation (LT) is selectively indicated because of splenoportal venous thromboses and increased sepsis. Therefore, its impact should be further investigated.MethodsOf the 160 liver transplant patients, only 40 underwent simultaneous splenectomy. Clinicopathologic characteristics and outcomes were compared between the splenectomy and non-splenectomy group using retrospective analysis.ResultsAlthough the groups were similar and had no significant difference in the intra- and postoperative data, non-splenectomy group had more male patients. However, splenectomy group showed significantly higher platelet and leukocyte counts at 1 month and 6 months after the transplantation and higher hepatitis C virus anti-viral therapy completion. Furthermore, 3 patients developed portal or splenic vein thrombosis during the postoperative follow-up, but the overall survival rate did not significantly differ between these groups.ConclusionSimultaneous splenectomy in LT can be safely performed, particularly in patients with hepatitis C virus cirrhosis, small-for-size grafts, hypersplenism, and ABO blood group incompatible (ABO - incompatible) LT.
