Outcomes of Robotic Pancreatectomy in the Octogenarian: A Multicenter Retrospective Cohort Study.

Abstract

Background/Objectives: Due to the increasing incidence of pancreatic and periampullary cancers with advancing age, coupled with the growing evidence supporting minimally invasive pancreatectomy, the demand for such procedures is rising. However, data on the feasibility of robotic pancreatectomy in octogenarian patients remain scant. This study aimed to investigate overall outcomes of robotic pancreatectomy and evaluate its safety and feasibility in octogenarian patients. Methods: A multicenter, retrospective study was conducted, including 380 patients who underwent robotic pancreatectomy at two high-volume centers in Japan from April 2020 to December 2024. Using prospectively collected data, we compared outcomes between younger patients (<80 years) and octogenarian patients (≥80 years). Multivariable logistic regression analyses were performed to assess the impact of age on postoperative outcomes. Results: Among the 380 patients, with a median age of 72 (interquartile range: 61-77) years, 213 underwent robotic pancreatoduodenectomy (RPD), and 167 underwent robotic distal pancreatectomy (RDP). Octogenarian patients were found to have more comorbidities and a higher incidence of malignant diseases. Octogenarians experienced significantly longer hospital stays post-RPD (22 [octogenarian; n = 36] vs. 14 [younger; n = 177] days, p < 0.001) and post-RDP (14 [n = 23] vs. 10.5 [n = 144] days, p = 0.02), yet their perioperative outcomes were comparable. Multivariable analyses indicated that age (≥80 years) was not a significant risk factor for major complications following robotic pancreatectomy (odds ratio, 1.33; 95% confidence interval, 0.59-2.84; p = 0.479). Conclusions: This multicenter study conducted at high-volume centers suggests that robotic pancreatectomy can be safely performed in carefully selected octogenarian patients.
