Combined robotic/open pancreaticoduodenectomy in the young aged < 50 years.

Impact of age on surgical and survival outcomes after combined robotic/open pancreaticoduodenectomy (CR/OPD) has not been extensively studied. This study aimed to evaluate the surgical and survival outcomes of patients aged < 50 years who underwent CR/OPD. A comparative study was conducted on patients who underwent CR/OPD divided into two groups: the young (age < 50 years) and the old (age ≥ 50 years). A total of 555 patients were included in this study, with 53 (9.5%) in the young group and 502 (90.5%) in the old group. Periampullary adenocarcinomas were less common in the young group (32.1% vs. 76.5%), whereas solid and pseudopapillary tumors (9.4% vs. 1.0%) and neuroendocrine tumors (15.1% vs. 3.6%) were more common. Soft pancreatic parenchyma (77.4% vs. 76.5%) and non-dilated (≤ 3 mm) pancreatic ducts (77.4% vs. 62.5%) were more prevalent in the young group. The young group had a shorter length of stay (median, 16 vs. 20 days). No significant differences were observed in the other surgical outcomes and risks, including postoperative pancreatic fistula (POPF) (7.5% vs. 8.0%). Survival outcomes for overall periampullary adenocarcinoma favored the young group, with a 5-year survival rate of 76.4% vs. 46.7% in the old group. In conclusion, RPD in the young patients (< 50 years) is associated with comparable surgical outcomes and favorable survival outcomes for periampullary adenocarcinoma compared with the older patients (≥ 50 years). These findings highlight the feasibility and safety of RPD in the young population, although the prevalence of soft pancreatic parenchyma and non-dilated pancreatic ducts was higher in the young group.
