Abstract：
BACKGROUND: Magnetic anchor technique (MAT) has been applied in laparoscopic cholecystectomy and laparoscopic appendectomy, but has not been reported in laparoscopic partial hepatectomy.
OBJECTIVE: To evaluate the feasibility of the MAT in laparoscopic left lateral segment liver resection.
METHODS: Retrospective analysis was conducted on the clinical data of eight patients who underwent laparoscopic left lateral segment liver resection assisted by MAT in our department from July 2020 to November 2021. The Y-Z magnetic anchor devices (Y-Z MADs) was independently designed and developed by the author of this paper, which consists of the anchor magnet and magnetic grasping apparatus. Surgical time, intraoperative blood loss, intraoperative accidents, operator experience, postoperative incision pain score, postoperative complications, and other indicators were evaluated and analyzed.
RESULTS: All eight patients underwent a MAT-assisted laparoscopic left lateral segment liver resection, including three patients undertaking conventional 5-port and five patients having a transumbilical single-port operation. The mean operation time was 138 ± 34.32 min (range 95-185 min) and the mean intraoperative blood loss was 123 ± 88.60 mL (range 20-300 mL). No adverse events occurred during the operation. The Y-Z MADs showed good workability and maneuverability in both tissue and organ exposure. In particular, the operators did not experience either a \"chopstick\" or \"sword-fight\" effect in the single-port laparoscopic operation.
CONCLUSIONS: The results show that the MAT is safe and feasible for laparoscopic left lateral segment liver resection, especially, exhibits its unique abettance for transumbilical single-port laparoscopic left lateral segment liver resection.

摘要：
背景：磁锚技术（MAT）已应用于腹腔镜胆囊切除术和腹腔镜阑尾切除术，但在腹腔镜肝部分切除术中尚未见报道。
目的：评价MAT在腹腔镜左侧段肝切除术中的可行性。
方法：回顾性分析了2020年7月至2021年11月在我科接受MAT辅助腹腔镜左外侧段肝切除术的8例患者的临床资料。Y-Z磁锚装置(Y-ZMAD)是本文作者自主设计研制的,它由锚磁铁和磁性抓具组成。手术时间,术中失血,术中意外,操作员经验，术后切口疼痛评分,术后并发症,等指标进行了评价和分析。
结果：所有8例患者均接受了MAT辅助的腹腔镜左外侧段肝切除术，包括三名接受常规五口手术的患者和五名接受经脐单口手术的患者。平均手术时间为138±34.32min（范围95-185min），平均术中出血量为123±88.60mL（范围20-300mL）。术中无不良事件发生。Y-ZMAD在组织和器官暴露中均显示出良好的可操作性和可操作性。特别是,操作人员在单孔腹腔镜手术中没有经历“筷子”或“剑斗”效果。
结论：结果表明，MAT用于腹腔镜左侧段肝切除术是安全可行的，尤其是,在经脐单孔腹腔镜左外段肝切除术中表现出独特的禁止性。
