Robotic pancreaticoduodenectomy in elderly and younger patients: A retrospective cohort study

Abstract

Background: Robotic pancreaticoduodenectomy (RPD) has gradually been accepted as it has overcome some of the limitations of laparoscopic surgery. Outcomes following RPD in elderly patients are still uncertain. This study aimed to evaluate the safety and feasibility of RPD in elderly patients.

Methods: The demographics and perioperative outcomes of a consecutive series of patients who underwent RPD between January 2018 and September 2019, were retrospectively analyzed. Patients were divided into 2 groups: elderly patients (≥75 years) and younger patients (<75 years).

Results: Of 431 patients who were included in this study, 77 were elderly patients and 354 were younger patients. Elderly patients had a significantly higher ASA score than younger patients (P < 0.001). There were no significant differences in operative time, estimated blood loss and blood transfusion rate between groups (P > 0.05). Elderly patients had significantly higher morbidity and longer postoperative hospital stay than younger patients (49.3% vs. 31.1%, P = 0.002; 22.8 vs. 13.3 days, P < 0.001, respectively). However, the reoperation, 90-day readmission and mortality rates were comparable in the two groups (P > 0.05). Multivariate analysis demonstrated that a higher ASA score was the only independent factor for postoperative morbidity (OR 2.02, 95% CI 1.06-3.88, P = 0.03), while old age was not (OR 0.81, 95% CI 0.36-1.81, P = 0.80).

Conclusion: This study demonstrated that RDP was safe and feasible in elderly patients. Age should not be a contraindication to RPD. Elderly patients with careful patient selection should be considered for RPD.
