Abstract: Objective: To evaluate the effects of implementing bundled nursing under the concept of accelerated rehabilitation surgery on elderly patients after pancreaticoduodenal surgery, in order to promote early postoperative recovery. Methods: Elderly patients who underwent pancreaticoduodenectomy at a tertiary grade A hospital in Beijing from August 2019 to March 2023 were selected and divided into the control group and the observation group which received bundled care measures based on the concept of Enhanced Recovery After Surgery. The two groups of patients were matched using a 1:1 propensity score ratio according to their baseline data, and the postoperative recovery of the two groups of patients was compared. Results: Better postoperative recovery of gastrointestinal function and shorter hospital stay were observed in the observation group than those in the control group. The incidences of postoperative gastric paralysis and lower limb venous thrombosis were lower than those in the control group (P<0.05). Conclusion: Bundled care based on the concept of Enhanced Recovery After Surgery can promote the recovery of gastrointestinal function in elderly patients after pancreaticoduodenal surgery, reduce the incidence of postoperative gastric paralysis and lower limb venous thrombosis, and shorten their hospital stay after surgery.
