以磁吻合技术：迎接微创外科新未来

Magnetic compression anastomosis： a promising technique in the further development of minimal invasive surgery

磁性压迫吻合技术（magnetic compression anastomosis，MCA）是利用永磁材料制成的吻合装置间的引力压迫脏器壁层造成局部缺血坏死而使管腔再通的非手术治疗方法。在血管介入技术的基础上利用磁性吻合技术可以实现腔内动、静脉吻合，显著缩短吻合时间，减少组织器官缺血损伤。MCA在临床上还可用于实现空腔脏器间的吻合（如胃肠吻合、胆肠吻合）以及活体肝移植和胆肠吻合术后严重并发症吻合口狭窄的重建，具有操作简单、快速、损伤小和并发症少的优点。MCA作为一种新的吻合技术将为微创手术的进一步发展开创崭新的未来。

Magnetic compression anastomosis （MCA） involves the use of two rare-earth magnets that attract to each other transmurally between two internal organs, resulting in compression and subsequent fistula formation to create a nonsurgical enteric, vascular, or biliary anastomosis with therapeutic aims. The magnetic vascular coupler allows a sutureless anastomoses between arteries and veins by using interventional radiological techniques. The MCA technique significantly reduces ischemic time during anastomosis, and has the advantages of low invasiveness and simplicity. It is a rather effective method for recanalizing between various hollow viscera, creating anastomosis such as gastrojejunostomy, choledochojejunostomy, or choledochoduodenostomy. Furthermore, this novel technique is considered to be a feasible and alternative reconstructive method for patients who develop significant bile duct complications following hepaticojejunostomy and living donor liver transplantation. MCA is a promising and novel technique in the further development of minimal invasive surgery.
