【Abstract】Objective To investigate the surgical technique of orthotopic liver transplantation using two-cuff technique and prevention of operational complications in rats. Methods The model was established with modified cuff technique.Before donor livers were harvested,the portal vein and hepatic artery were interrupted for 10 min,and reflow was initiated for another 10 min.The donor liver was perfused through abdominal aorta and portal vein respectively.The infrahepatic vena vein and portal vein were anastomosed by means of cuff method； the anastomosis of the suprahepatic vena vein was performed with suture method. The anastomosis of the common bile duct was performed with an internal stent. Results One hundred and twenty rats underwent orthotopic liver transplantation using twocuff technique and the successful rate was 90.8%. The average nonhepatic time of recipients was (21.0±3.5) min and the total surgical time was (46.0±4.5) min. The oneweek survival rate of recipients was 87.2%. Conclusion Good exposure of operative field, sophisticated microsurgical technique and delicate surgical manipulation can benefit decreasing nonhepatic and total surgical time of recipients and increasing the survival rate of recipients.
