Abstract:
Objective: To investigate the efficacy and safety of liver venous deprivation (LVD) before secondary resection of primary liver cancer. Methods: 56 patients with advanced primary liver cancer who were not suitable for primary resection in Liver Surgery Department of Xinxiang Central Hospital from January 2018 to January 2019 were analyzed retrospectively. They were divided into liver vein deprivation group (LVD group: LVD+ PVE, n=26) and portal vein embolization group (PVE group, n=30). The dynamic changes of liver reserve function and future liver remnant volume (FLR-V), R0 resection rate, surgical complications, postoperative recurrence rate and overall survival rate of two groups before and after LVD/PVE were compared. Results: The success rate of puncture and embolization in LVD group and PVE group was 100%. There were no grade Ⅳ complications, and there was no significant difference of grades Ⅰ, Ⅱ and Ⅲ complications between the groups (P=0.808). The FLR-V of LVD group before embolization, 7, 14 and 21 days after embolization was (493.1±25.8), (673.2±56.1), (779.5±81.6) and (853.3±85.2) cm(3), respectively. The FLR-V of PVE group before embolization, 7, 14 and 21 days after embolization were (502.4±20.1), (688.6±43.9), (656.8±73.7) and (563.5±69.1) cm(3), respectively. There was no significant difference in FLR-V between the two groups before and 7 days after embolization (P>0.05). The FLR-V of LVD group was higher than that of PVE group at 14 and 21 days after embolization (P<0.01). The preparation time of LVD group was (20.4±6.3) days, which was shorter than that of PVE group [(31.5±8.8) days, P=0.045]. The rate of secondary hepatectomy was 92.3% (24/26), which was higher than that of PVE group [70.0% (21/30), P=0.036]. The R0 resection rate was 87.5% (21/24), which was higher than that of the PVE group [57.1% (12/21), P=0.022]. However, there were no significant differences in surgical methods, operation time, intraoperative blood loss, Clavien-Dindo complication grade and length of hospital stay between the two groups (P>0.05). After hepatectomy, the median recurrence time and median survival time of LVD group were 12.6 months and 21.3 months, respectively, which were longer than those of PVE group (9.4 months and 13.5 months, respectively, P<0.01). Conclusions: For patients with advanced liver cancer who are not suitable for primary hepatectomy, preoperative LVD can significantly increase FLR-V, improve the resection rate of secondary surgery, shorten the preparation time of two operations, and do not increase surgical complications. Moreover, patients with LVD can improve the R0 resection rate of secondary surgery. The postoperative recurrence time and overall survival rate of patients with LVD are better than those of patients with PVE, and LVD has a good long-term effect.
