Value of Anatomical Liver Resection in the Treatment of Liver Cancer Complicated with Microvascular Invasion/CAO Yuming.//Medical Innovation of China， 2025， 22(12)： 073-076

    [Abstract]Objective：To investigate the clinical value of anatomicalliver resection (AR)in the treatment of liver cancer complicated with microvascular invasion (MVI).Method：Theclinical data of 97 patients withliver cancer complicated with MVI admitted to Jinan Tianqiao People's Hospital from February 2019 to January 2022 were retrospectively analyzed.According to diffrent surgical methods，they were divided into observation group (receiving AR， n=54) and control group [receiving non-anatomical liver resection (NAR)， n =43]. Surgery and tumor related indexes were compared between the two groups， and postoperative survival rates were recorded during follow-up.Result：Theoperation time of theobservation group waslongerthan thatof the control group，the amount of blood lossduring operation waslessthan thatof thecontrolgroup，therate ofbloodtransfusion during operation was lower than that of the control group，the postoperative extubation timeand postoperative hospitalization time were shorter than those of the control group ( P lt;0.05). The incidence of postoperative complications in observation group was lower than that in control group ( P lt;0.05). The 3-year none tumor survival rate of observation group was higher than that of control group ( P lt;0.05). There was no significant difference in the 3-year overall survival rate between the two groups (Pgt;0.05) . Conclusion： AR treatment of patients with liver cancer complicated with MVI has less intraoperative bloodloss ......
