Complete or partial split in associating liver partition and portal vein ligation for staged hepatectomy: A systematic review and meta-analysis

Figure 1 Flowchart for identifying eligible studies and study selection process.

Figure 2 Meta-analysis and subgroup analysis of morbidity in p-ALPPS vs ALPPS (Dindo-Clavien classification ≥ 3a). ALPPS: Associating liver partition and portal vein ligation for staged hepatectomy; p-ALPPS: Partial split of the liver parenchyma in associating liver partition and portal vein ligation for staged hepatectomy; CI: Confidence interval.

Figure 3 Meta-analysis and subgroup analysis of postoperative mortality in p-ALPPS vs ALPPS. ALPPS: Associating liver partition and portal vein ligation for staged hepatectomy; p-ALPPS: Partial split of the liver parenchyma in associating liver partition and portal vein ligation for staged hepatectomy; CI: Confidence interval.

Figure 4 Meta-analysis of p-ALPPS vs ALPPS, and comparison of FLR hypertrophy in none-cirrhosis group. FLR: Future liver remnant; ALPPS: Associating liver partition and portal vein ligation for staged hepatectomy; p-ALPPS: Partial split of the liver parenchyma in associating liver partition and portal vein ligation for staged hepatectomy; CI: Confidence interval.
