Abstract
ObjectiveThis is a case report on a patient with advanced hepatic alveolar echinococcosis (HAE) treated with autologous liver transplantation without any veno-venous bypass using the modified technique of ex vivo liver resection and autologous liver transplantation (the ERAT technique). MethodA 27-year old male with advanced HAE underwent in situ reconstruction of vascular inflow/outflow to left lateral liver section, ex-vivo liver resection and autologous liver transplantation of remaining liver remnant (the modified ERAT technique). The operation consisted of hepatotomy along the right border of the falciform ligament, reconstruction of portal vein supplying the left lateral liver section, reconstruction of left hepatic vein, followed by removal of liver segments S1, S4 to S8, ex vivo resection of all involved tissues within these liver segments in the liver remnant, and autologous liver transplantation of the resected liver remnant. The whole surgical procedure lasted for 12 h, and the blood lost was 800 mL. The patient recovered uneventfully in the post-operation period. ConclusionThe in situ reconstruction of the vascular inflow/outflow of left lateral liver section maintained the PV circulation and provided liver functional support during the operation. The subsequent autologous liver transplantation provided additional liver functional tissues, thus reduced the risk of post-hepatectomy liver failure. This surgical procedure did not require any veno-venous bypass.
Highlights
Hepatic alveolar echinococcosis (HAE) is a life-threatening disease characterized with a long incubation period, with invasion of multiple intrahepatic structures, resulting in difficulties in resection [1]
Intrahepatic vessels and bile ducts could be complexly involved in patients with end-stage HAE, presenting with difficulties for radical resection
Ex-vivo liver resection and autologous liver transplantation (ERAT) using living donor livers have been used for treatment of patients with end-stage hepatic AE [8,9,10,11]
