Abstract:Objective
To study donor liver repair in modified piggyback liver transplantation and its relationship to postoperative complications.
Methods The relationship between donor liver repair and development of complications of 14 cases of modified piggyback liver transplantation,which among 17 cases of orthotopic piggyback liver allotransplantation performed in our hospital,were analyzed retrospectively.In the 14 cases,abnormal hepatic artery was repaired in 2 cases,portal vein interposition shunt was done in 1 case;repaired ligaments were sutured in 10 of 14 cases,and not sutured in 4 cases.
Results None of the 14 patients died in the perioperative period. The success rate of the operation was 100%. 3 patients had intraabdominal bleeding,postoperatively,and in 2 cases the bleeding was related to donor liver repair. Postoperatively,there was no thrombosis of hepatic artery or portal vein, and no bile duct necrosis, no hepatic outflow tract occlusion. Conclusions Donor liver repair is an important procedure in liver tramsplantation.The quality of donor liver repair is directly related to the difficulty of operative technique during liver transplantation,and to the development of postoperative complications.In donor liver repair during piggyback liver transplantation,reconstruction of the retrohepatic vera cava is very important.The constructed stoma must be compatible with the donor hepatic vein outflow stoma and be able to effectively prevent the formation of eddy blood flow,ensure patency of the outflow tract and effectively prevent thrombus formation.
