The Feasibility of Uniportal Video-Assisted Thoracic Surgery in Octogenarians: A Propensity-Matched Comparative Analysis

Year: 2026

Type: article

Abstract: Objectives: To evaluate the short-term safety (30-day and in-hospital morbidity and mortality) and technical feasibility of uniportal video-assisted thoracic surgery (U-VATS) for anatomical lung resection in octogenarians (≥80 years) compared with younger patients (<80 years) at a single center. Methods: Ninety consecutive patients undergoing U-VATS anatomical lung resections between January 2020 and January 2024 were retrospectively analyzed. Patients were stratified by age: 60 patients < 80 years and 30 octogenarians ≥ 80 years. Propensity score matching (nearest-neighbor, 1:2 ratio, caliper 0.2 SD) yielded a matched cohort of 60 patients (40 younger, 20 octogenarians) for comparative analysis. Results: After matching, standardized mean differences (SMD) were <0.25 for most covariates, indicating good balance. Octogenarians demonstrated lower FEV1 (75.2 ± 15.3% vs. 87.5 ± 18.2%, p = 0.012) and DLCO (68.4 ± 12.1% vs. 78.5 ± 14.3%, p = 0.009), consistent with age-related pulmonary changes. Charlson Comorbidity Index was higher (5.3 ± 1.2 vs. 3.8 ± 1.4, p = 0.001). Surgical parameters were comparable: operative time (143.80 ± 42.3 vs. 136.55 ± 38.7 min, p = 0.524), blood loss (median 80 [IQR 50–120] vs. 95 [IQR 60–130] mL, p = 0.742). Zero conversions occurred. Major complications (Clavien–Dindo ≥ 3) occurred in 10% vs. 0% (absolute risk difference 10%, 95% CI: −3.2% to 23.2%). No 30-day mortality. 90-day mortality: 5% vs. 0% (p = 0.333); one-year: 15% vs. 0% (p = 0.035). Conclusions: U-VATS is technically feasible in carefully selected octogenarians with comparable intraoperative parameters to younger patients. Postoperative recovery differed meaningfully, with higher delirium rates, longer hospitalization, and greater rehabilitation needs. One-year mortality was higher in octogenarians, reflecting competing comorbid risk rather than surgical harm. Residual imbalance in comorbidity burden and pulmonary reserve after matching limits causal inference. These hypothesis-generating findings support U-VATS in selected octogenarians when comprehensive geriatric assessment and structured delirium prevention guide perioperative management; validation in larger multicenter prospective studies is required.
