Is laparoscopic liver resection safe for super-elderly patients (aged ≥80)? A propensity score-matched analysis

BACKGROUND/PURPOSE The safety of laparoscopic liver resection in super-elderly patients with comorbidities is unknown. We used propensity score matching to evaluate the utility and safety of laparoscopic liver resection in super-elderly patients. METHODS Two-hundred and five patients who underwent laparoscopic liver resection were retrospectively reviewed. They were classified into two groups based on age: ≥80 years (elderly group, n = 49) and <80 years (control group, n = 156). Propensity score matching (PSM) was performed based on preoperative clinical parameters. The intraoperative and postoperative outcomes were compared. RESULTS After matching, 45 patients were included in each group. The intraoperative blood loss was identical between the control and elderly groups (60 vs 60 mL, respectively, P = .588); the frequency of serious postoperative complications (Clavien-Dindo class ≥3, 1/45 vs 1/45, P = 1.00) was also similar. There was no significant difference in terms of the exacerbation of malignancy (22.2% vs 11.1%, P = .258) or other diseases (8.9% vs 22.2%, P = .144). There was no difference in overall survival before and after PSM. However, 5-year overall survival excluding primary cancer-related death showed a difference after PSM (90.7% vs 70.4%; P = .048). CONCLUSIONS Laparoscopic liver resection is feasible and safe in super-elderly patients. The long-term prognosis was poor in patients affected by other illnesses compared to the younger population with similar risk profiles, but there was no difference in overall survival.
