AbstractIt is still controversial whether associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or traditional staged hepatectomy such as portal vein embolization (PVE) and 2-staged hepatectomy (TSH) is better. The aim of this study was to compare these 3 available strategies in extended hepatectomy.Trials were identified by searching MEDLINE, PubMed, the Cochrane Library, and Embase and additional articles were identified by hand searching. Comparative clinical studies reporting volumetric changes, mortality, morbidity, and feasibility of the second stage about ALPPS versus PVE or ALPPS versus TSH were included.Nine studies involving 557 patients met the inclusion criteria. Five studies reported on comparison of ALPPS and PVE, and the other 4 reported about ALPPS and TSH. In the comparison of ALPPS versus traditional staged hepatectomy (PVE and TSH), ALPPS was associated with a greater increase in the future liver remnant (FLR) (RR: 4.87; 95%CI, 3.41-6.33) and more frequent completion of stage 2 resection (RR: 1.32; 95%CI, 1.21-1.44). Compared with the traditional staged hepatectomy, ALPPS had a trend toward higher morbidity (RR: 1.19, 95%CI, 0.96-1.47) and mortality (RR: 2.11, 95%CI, 1.02-4.33) after stage 2 resection.ALPPS is associated with greater future liver remnant hypertrophy and a higher rate of completion of stage 2, but this may be at the price of greater morbidity and mortality.
