Liver transplantation in patients with situs inversus.

Situs inversus has been considered an absolute contraindication to liver transplantation due to technical difficulties. Associated vascular malformation and distorted anatomy may make the procedure even more complicated or impossible. Only three cases of patients with abdominal situs inversus who underwent successful liver transplantation have been reported in the English literature. We describe two additional patients with situs inversus who suffered from biliary atresia and underwent successful liver transplantation. The preoperative evaluation and the operative procedure are presented, and technical difficulties are discussed. Since biliary atresia is associated with polysplenia syndrome, including vascular malformation and visceral malposition, we suggest that each case be extensively evaluated preoperatively to determine the size requirement for the donor liver and the feasibility of reconstruction.
