Surgical Risks and Survival Outcomes in Robotic Pancreaticoduodenectomy for the Aged Over 80: A Retrospective Cohort Study.

Abstract

Whether to execute pancreaticoduodenectomy or not for older people could pose a dilemma. This study clarifies the safety and justification of robotic pancreaticoduodenectomy (RPD) for older individuals over 80. A total of 500 patients undergoing RPD were divided into group O (≥ 80 y/o) and group Y (< 80 y/o) for comparison. There were 62 (12.4%) patients in group O. Surgical mortality was 1.6% for overall patients and higher in group O, 6.5% vs 0.9%; p = 0.001. The surgical complication was comparable between groups O and Y. Delayed gastric emptying and bile leakage were higher in group O, 9.7% vs 2.5%; p = 0.004, and 6.5% vs 0.9%; p = 0.001, respectively. Length of stay was also longer in group O, with a median of 26 vs 19 days; p = 0.001. Survival outcome after RPD was poorer in group O for overall periampullary adenocarcinomas, with a 5-year survival of 48.1% vs 51.2%; p = 0.025 and also for the subgroup of pancreatic head adenocarcinoma, with a 3-year survival of 27.4% vs 42.5%; p = 0.030. RPD is safe and justified for the selected octogenarians and even nonagenarians, whoever is fit for a major operation. Nevertheless, pancreatic head cancer and higher mortality risk for the aged over 80 with advanced ASA score ≥ 3 should be informed as part of counselling in offering RPD.
