Objective To investigate the short‑term outcomes of robot-assisted pancreato-duodenectomy (RPD) performed by one single surgeon.

Methods The retrospective and descriptive study was conducted. The clinico-pathological data of 240 patients who were performed RPD by one single surgeon at The First Affiliated Hospital of Sun Yat‑sen University from July 2016 to October 2023 were collected. There were 130 males and 110 females, aged 59(19)years. All RPD were performed by the same surgeon. Observation indicators: (1) surgical situations; (2) postoperative pathological examination and outcome of patients. Measurement data with normal distribution were expressed as Mean±SD, and measurement data with skewed distribution were expressed as M(IQR). Count data were expressed as absolute numbers or percentages.

Results (1) Surgical situations. Of 240 patients, 15 cases underwent combined vascular resection and reconstruction, and 13 patients were combined with other operations simultaneously. Of 240 patients, 4 cases converted to open surgery, with the conversion rate as 1.67%. The operation time of 240 patients was 458(152)minutes, volume of intraopera-tive blood loss was 50(50)mL, intraoperative erythrocyte transfusion was required in 17 patients. The R₀ resection rate was 99.17%(238/240), the number of lymph nodes harvested was 10(6) and duration of postoperative hospital stay was 17(12)days. (2) Postoperative pathological examination and outcome of patients. Of 240 patients, 51 cases were pancreatic ductal adenocarcinoma, 41 cases were ampullary carcinoma, 41 cases were neuroendocrine neoplasms, 35 cases were pancreatic cystic neoplasms, 28 cases were duodenal carcinoma and 44 cases were other pathologic types. Of 99 patients with major complications, there were 57 cases with clinically relevant postoperative pancreatic fistula, 44 cases with postoperative delayed gastric empty, 11 cases with postoperative biliary fistula, 8 cases with postoperative chyle fistula, 14 cases with incision infec-tion, and 24 cases with postoperative hemorrhage. Multiple complications might occur to the same patient. Reoperation was performed in 6 of the 240 patients. One patient died within 30 days after surgery. Twenty-four patients returned to hospital within 30 days after discharge.

Conclusions RPD performed by one single surgeon is safe and feasible, with favorable short‑term outcomes, which can be performed in medical centers with experiences in robot‑assisted pancreatic surgery.
