Central Liver Segments Resections vs Extended Hepatectomies in Children: Single-Center Experience

Background: Central liver segments resection (CLSR) still is not widely used in pediatric surgery due to its technical difficulty, whereas this procedure is widely spread as a parenchyma sparing approach of centrally located liver tumors in adults. The aim of this study is to analyze the outcomes of CLSR in comparison with extended hepatectomy (EH) in children with different liver tumors. Methods: A single-center retrospective analysis of patients who received CLSR (n = 14) and EH (n = 44) from June 2017 to December 2023 was applied. Patient's characteristics, preoperative, intra- and postoperative data were compared between 2 groups. Results: Preoperative CT-volumetry showed that future liver remnant volume was higher in CLSR group compared to EH (FLR-V; (54 +/- 29 (40-91) % vs 40 +/- 12 (17-73) %, p = 0.016). The intraoperative blood loss (200 [90-1150] (20-3000) ml vs 100 [30-275] (10-9000) ml, p = 0.088) and transfusion volume (310 [85-590] (0-1860) ml vs 150 [0-310] (0-4770) ml, p = 0.484) were similar in both groups, while operation time was longer in CLSR group (420 [320-595] (145-785) min vs 280 [203-390] (125-710) min), p = 0.011). There was no difference in biliary leakage (3 (21.4 %) vs 12 (27.3 %); p = 0.479), other complications (4(28.6 %) vs 5(11.4 %), p = 0.198) and complications > IIIb by Clavien-Dindo (2(14.3 %) vs 8 (18.2 %), p = 0.385) postoperatively. Conclusion: CLSRs allow to preserve more healthy liver parenchyma compared to EH with similar intraoperative and postoperative outcomes. << Extended mesohepatectomy >> allows to achieve R0 resection when central liver tumor extends on the left lateral and/or right posterior section.
