To explore the clinical application of a newly developed magnetic anchoring traction (MAT) system in the liver bench trimming and transplantation surgery.
The conventionally limited space, vision, and exposure have always been a challenge for the quality of surgery in the liver bench trimming due to the fact that the exposure depends largely on the experience of surgeon. To deal with this problem, a MAT system is developed as an alternative support to enhance exposure. The preliminarily experiments on animals verified its feasibility and reliability in the practical use, and its clinical application and effects were examined in the present research.
A total of 20 DCD (donation of cardiac death) donor livers were collected and divided evenly between the magnetic anchor traction (MAT) assisted group (n = 10) and the manual assisted group (n = 10). The results and quality assessment from experts about the liver bench surgery performed by two groups were examined and compared.
The MAT system can be employed effectively to compete and replace the manual assistance to achieve a better exposure in the liver bench trimming. No statistical difference was found regarding the baseline data between the MAT and the manual groups. In the inferior vena cava and hepatic artery trimming, the MAT group outperformed the manual group remarkably in many aspects. The surgery time for liver bench shortened considerably after a quick grasp of MAT skills by surgeons.
The MAT system provides a more stable, reliable and qualified local exposure in the liver bench surgery, and can preferably be employed to replace the manual assistance in the procedures of liver transplantation.
探讨一种新开发的磁锚定牵引（MAT）系统在肝脏修整及移植手术中的临床应用。
传统上，由于肝脏修整手术的暴露很大程度上依赖于外科医生的经验，有限的空间、视野和暴露一直是肝脏修整手术质量的一大挑战。为解决这一问题，开发了一种MAT系统作为增强暴露的替代支持。动物初步实验验证了其在实际应用中的可行性和可靠性，本研究对其临床应用及效果进行了考察。
共收集20例心脏死亡器官捐献（DCD）供肝，平均分为磁锚定牵引（MAT）辅助组（n = 10）和手动辅助组（n = 10）。对两组进行的肝脏修整手术的结果及专家质量评估进行检查和比较。
MAT系统可有效用于竞争并替代手动辅助，在肝脏修整中实现更好的暴露。MAT组和手动组的基线数据无统计学差异。在下腔静脉和肝动脉修整方面，MAT组在许多方面明显优于手动组。外科医生快速掌握MAT技术后，肝脏修整手术时间大幅缩短。
MAT系统在肝脏修整手术中提供了更稳定、可靠和合格的局部暴露，在肝移植手术过程中可较好地用于替代手动辅助。
