Modified piggyback liver transplantation:a report of 14 cases / 中国普通外科杂志

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.
