With the aging of society, surgical patients are becoming older. The same trend can be seen in patients undergoing highly invasive operations, such as pancreaticoduodenectomy(PD). The risk of postoperative complications is reportedly higher in patients of advanced age, and postoperative pneumonia occurs at particularly high frequency. We investigated the safety of PD in patients of advanced age with a focus on the prevention of postoperative pneumonia. In total, 223 patients underwent PD at our department from January 2015 to December 2020. We compared various parameters between older patients(≥80 years of age, n=32)and younger patients(<80 years of age, n=191). Although older patients had lower nutrition scores, there was no significant difference in the incidence of postoperative complications between the two groups. Three older patients who were undergoing swallowing rehabilitation by a speech-language therapist did not develop postoperative pneumonia. However, one patient who did not receive swallowing rehabilitation developed postoperative pneumonia. Based on these findings, we plan to incorporate swallowing evaluation before postoperative oral intake into the clinical pathway and introduce speech-language therapy intervention in patients of advanced age.
