Laparoscopic versus open pancreaticoduodenectomy outcomes in patients ≥ 75 years old: an NSQIP analysis of 4343 patients.

BACKGROUND

The benefits of MIS in older adults are conflicting. This study evaluates demographics and early outcomes, for older patients (≥75) undergoing minimally invasive (MIS) versus open pancreaticoduodenectomy (PD).

METHOD

We categorized elderly patients who underwent PD from 2017 to 2021 NSQIP databases by surgical approach (open vs MIS). Baseline characteristics were examined with bivariate analysis, and multivariate logistic regression assessed the independent effect of minimally invasive surgery on 30-day serious complications and mortality.

RESULTS

Amongst 4137 patients, 150 (3.63 %) underwent MIS PD. Patients demographics were similar. Open cohorts were older (79.1 vs 78.4 years; p = 0.011) with greater tumor invasion (36.6 % vs. 27.0 %; p = 0.018). MIS had longer operations (133.1 vs 119.6 min; p < 0.001). Multivariate analysis demonstrated that MIS approach was associated with increased serious complications (OR 2.21; p < 0.001), but not mortality (OR 2.11; p = 0.173). Post hoc analysis excluding cases converted to open demonstrated no difference in serious complications (OR 1.94; p = 0.070) or mortality (OR 3.58; p = 0.094). PSM analysis estimated a 14.7 % higher rate of serious complications in MIS but similar mortality (p = 0.291).

CONCLUSIONS

MIS PD uptake in elderly patients remains limited, with early findings indicating longer operations and higher complications. Further research on patient selection differences, technique modifications, and center expertise is required.
