ROBOT‐assisted pancreatoduodenectomy in 300 consecutive cases: Annual trend analysis and propensity score‐matched comparison of perioperative and long‐term oncologic outcomes with the open method

摘要

Abstract Background/Purpose We previously reported perioperative and oncologic outcomes of robot‐assisted pancreatoduodenectomy (RAPD); however, the follow‐up period in RAPD was relatively short, and disease‐matched survival analyses were lacking. Therefore, this study investigated time trends of perioperative and long‐term disease‐matched outcomes of RAPD. Methods Annual clinicopathologic outcomes of 328 patients with RAPD between 2015 and 2020 were analyzed and compared with 929 patients with open PD using the propensity score‐matched (PSM) analysis based on postoperative pancreatic fistula (POPF) risk and oncologic variables in malignant patients. Results Robot‐assisted pancreatoduodenectomy cases increased from 10 (6.3%) in 2015 to 116 (50.2% of total PD) in 2020, with malignancy proportion increasing from 50.0% to 80.2%. POPF risk‐based PSM analysis showed that compared with open PD, RAPD had younger patients (63.7 vs 65.6?years, P?=?.018), longer operation time (339.1 vs 290.0?min, P?
