[Meta-analysis of the outcomes of associating liver partition and portal vein ligation for staged hepatectomy versus portal vein embolization for the treatment of liver cancer with insufficient future liver remnant].

Abstract

Objective: To explore the feasibility, safety and efficacy of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and portal vein embolization (PVE) for the treatment of liver cancer with insufficient future liver remnant (FLR) . Methods: The data regarding the clinical controlled trials in comparison of ALPPS and PVE in liver surgery were collected from the both domestic and international publications searched through the datebases of PubMed, Cochrane Library, Embase, CNKI, and VIP.Meta analysis was performed by RevMan 5.3 software. Results: Total 10 studies with clinical control were analyzed (9 cohort studies and 1 randomized controlled study) .A total of 620 patients were included, with 165 cases in ALPPS group, 455 cases in PVE group.Results of Meta-analysis showed that there was statistically significant difference (P<0.05) between the two groups in the completion rate of two-steps surgery (OR=6.04, 95%CI: 2.97-12.31, Z=4.96) , FLR growth rate (MD=19.91, 95% CI: 8.64-31.18, Z=3.46) , two-steps surgical interval (MD=-30.48, 95%CI: -37.87--23.09, Z=8.09) , and R0 resection rate (OR=2.29, 95%CI=1.07-4.90, Z=2.13) .While there was no significant differences between the two groups in the mortality rate of postoperative within 90-days, postoperative the total complication rates, postoperative liver failure, and total hospital stay (all P>0.05) . Conclusions: Compared to the PVE procedures, ALPPS appears an effective treatment method for liver tumor with insufficient FLR.Therefore, the applications of ALPPS and PVE are limited and depending on further investigation.
