  • Application of hepatic outflow reconstruction with allograft vascular in ex-vivo liver resection and autologous liver transplantation

    ObjectiveTo explore the effect of hepatic outflow reconstruction with allograft vascular in ex-vivo liver resection and autologous liver transplantation.MethodThe clinical data of a patient with end-stage hepatic alveolar echinococcosis admitted to the Organ Transplantation Center of Sichuan Provincial People’s Hospital in August 2019 who underwent the ex-vivo liver resection and autologous liver transplantation combined with hepatic vein reconstruction with allograft vascular were analyzed retrospectively.ResultsThe patient, a 44-year-old female, was admitted to Sichuan Provincial People’s Hospital for “pain in the right abdomen accompanied by skin and sclera yellow staining for 6+ months and aggravated for 20+ d”. When the patient was admitted, the general condition was poor, such as hyperbilirubin and hypoproteinemia. The body mass was 45 kg and the standard liver volume was 852 mL. The hydatid lesions corroded the first and second hilum of the liver, the right hepatic vein and the posterior inferior vena cava. It was difficult to reconstruct the outflow tract of the hepatic vein in vivo, and it was extremely difficult to completely remove the hydatid lesions in vivo. After admission, the patient was generally in a good condition after the PTCD treatment, then after discussion and rigorous evaluation, the ex-vivo hepatectomy combined with autologous liver transplantation was required. The operative time was 15 h and the intraoperative blood loss was approximately 2 000 mL. After the operation, the routine treatment was performed, the antiviral treatment was continued, the international standardized ratio value was monitored at 1.5–2.5, and the anti-immune rejection drugs were not needed. The patient was transferred to the general ward on the 4th day after the operation, and there were no bile leakage, bleeding, infection and other complications. the result of postoperative pathological diagnosis was the alveolar echinococcosis. The re-examination of enhanced CT on 1 week after the operation suggested that the hepatic outflow tract of allograft vascular reconstruction was unobstructed, no stenosis and no thrombosis occurred. The patient was following-up at present.ConclusionsIn treatment of end-stage hepatic alveolar echinococcosis by autologous liver transplantation, reconstruction of hepatic outflow should be individualized. Allograft venous vessels could be used as ideal materials due to their advantages of matched tube diameter and length, no anti-rejection, and low risk of infection.

  • Application of hepatic vein reconstruction with various vascular materials in treatment of end-stage hepatic alveolar echinococcosis by ex-vivo liver resection and autologous liver transplantation

    ObjectiveTo summarize the key operative points and efficacy of ex-vivo ex-vivo liver resection and autologous liver transplantation (ELRA) using various vascular materials for hepatic vein reconstruction in the treatment of end-stage hepatic alveolar echinococcosis (HAE). MethodThe clinicopathologic data of a patient with end-stage HAE who underwent ELRA combined with complex hepatic vein reconstruction were retrospectively analyzed. ResultsThe patient was a 60-year-old male who was admitted to the Sichuan Provincial People’s Hospital due to giant alveolar hydatid in the liver, with a body weight of 60 kg and a standard liver volume of 1 024.5 mL. The imaging showed that the hydatid invaded the first and second hepatic portals, middle hepatic vein, left hepatic vein, and retrohepatic inferior vena cava. The three-dimensional reconstruction of CT showed that the residual liver volume was 1 270.6 mL. The patient received supportive treatment after admission and underwent ELRA following strict evaluation. Intraoperatively, it was found that the multiple hepatic veins and retrohepatic inferior vena cava were widely invaded. The liver was split in vivo and the mass was excised ex vivo by “in vivo first” principle. The hepatic vein was repaired and reconstructed into a wide mouth outflow tract using allogeneic veins, autologous inferior mesenteric vein, and hepatic round ligaments, then performed the autotransplantation by wide mouth outflow-artificial inferior vena cava anastomosis (end to side). The operative time was 16 h, and the intraoperative blood loss was approximately 2 000 mL. FK506 was orally administered after operation, and low-molecular-weight heparin sodium was administered 24 h later for anticoagulation. The patient was returned to the general ward on the 6th day after the operation, and the enhanced CT scan showed that the hepatic outflow tract was unobstructed, without stenosis and thrombosis, and the patient was discharged on day 18 after the operation. The patient was pathologically diagnosed with alveolar echinococcosis. ConclusionsFrom the results of this case, combination of multiple vascular materials to reconstruct the hepatic outflow tract is an optional procedure for ELRA in treatment of end-stage HAE. Strict preoperative evaluation, skillful vascular anastomosis technique, and postoperative anticoagulation are important measures to maintain patency of postoperative reconstruction vessel.
