摘要 目的探讨成人间双活体供肝移植的手术重建技巧。方法2例成人患者,1例原发病为乙型肝炎后肝硬化、巨块型肝癌,接受其2位姐姐的左半肝移植,移植物与受者体重比(GR/WR)为1.5%,移植于原肝位置左侧的左半肝,其肝左静脉、门静脉分别于受者的肝左静脉、门静脉左支端端吻合,胆肠吻合方式重建供肝胆道;移植至右侧的左半肝,沿矢状位旋转180°,其肝左静脉、门静脉分别与受者的肝右静脉、门静脉右支端端吻合,左肝管与受者的肝总管端端吻合。另1例原发病为乙型肝炎后肝硬化,接受其母亲的右半肝移植,但由于供肝存在大泡状空泡变性,且供、受者的体重差较大,为能满足患者的生理需要,故该例同时行尸体左半肝移植,GR/WR为1.2%,右半肝的肝右动脉、肝右静脉分别于受者的同名血管端端吻合,其门静脉与受者的门静脉右支端端吻合,右肝管与受者的肝总管端端吻合;左半肝的肝左静脉、门静脉及肝动脉分别与受者的肝左静脉、门静脉左支及脾动脉端端吻合,胆肠Roux-en-Y吻合方式重建供肝胆道。结果除母亲供者术后3d出现短暂乳糜漏,经对症治疗11d后痊愈外,供者无其它并发症发生。2例患者术后恢复良好,未发生排斥反应及全身感染,现已随访10个月以上,肝功能正常,均恢复正常工作和生活。结论成人间双活体供肝移植可为受者提供更大的肝脏,又可减少供者的风险,但手术操作复杂,需要对供、受者的条件进行充分评估后施行。 Objective To explore the surgical reconstructive procedures of adult-to-adult living donor liver transplantation (LDLT). Methods Two patients with end-stage liver disease were successfully subjected to adult-to-adult LDLT using dual grafts in our division. One patient's donors were left lobe and left lobe from his two old sisters, respectively. The other graft was right lobe from his 56 years old mother and left lobe separated from a cadaveric organ donor. Results Both recipients and three donors display good graft function and normal triangular shape regeneration of their liver grafts after liver transplantation. There was neither mortality nor serious complications in the donors. Conclusion The critical issue of LDLT is donor morbidity. Dual grafts from two living donors can help to alleviate the problem of small for-size grafts and yet secure the safety of the donor. But the complicated surgical techniques give a great challenge for liver transplant surgeons.
