Laparoscopic versus open liver resection for multiple hepatocellular carcinoma within and beyond the Milan criteria: An Eastern-Western propensity score-matched analysis
JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES(2024)
Abstract
Background: There is still little knowledge about the outcomes of laparoscopic liver resection (LLR) for multiple hepatocellular carcinomas (HCC). The aim of this study was to assess the short- and long- term outcomes of LLR versus open liver resection (OLR) for patients with multiple HCC within and beyond the Milan criteria, and in both BCLC-A and -B stage.Methods: Data regarding all consecutive patients undergoing liver resection for multiple HCC were retrospectively collected from Asian (South Korean) and European (Italian) referral HPB centers. The cases were propensity-score matched for age, BMI, center, extent of the resection, postero-superior location of the lesion, underlying liver condition, BCLB staging and the Milan criteria.Results: A total of 203 patients were included in the study: 27% of patients had undergone hemi-hepatectomy, 26.6% atypical resections, 20.6% sectionectomy and 16.2% segmentectomy. After PSM two cohorts of 57 patients were obtained, with no significant differences in all preoperative characteristics. The length of hospital stay was significantly lower after LLR (median 7 vs. 9 days, p < .01), with no statistically significant differences in estimated blood loss, operation time, transfusions, postoperative bile leak, ascites, severe complications and R1 resection rates. After a median follow-up of 61 (+/- 7) months, there were no significant differences between OLR and LLR in both median OS (69 vs. 59 months, p = .74, respectively) and median DFS (12 vs. 10 months, p = .48, respectively).Conclusion: LLR for multiple HCC can be safe and effective in selected cases and is able to shorten median hospital stay without affecting perioperative and long-term oncological outcomes.
