Advancing the Time to the Initiation of Adjuvant Chemotherapy and Improving Postoperative Outcome: Enhanced Recovery after Surgery in Pancreaticoduodenectomy.

Early initiation of chemotherapy could improve overall survival after pancreaticoduodenectomy (PD). The concept of enhanced recovery after surgery (ERAS), which aims to reduce the stress response to surgery and accelerate recovery, is relatively limited in PD. The aim of the study was to retrospectively analyze the relationships of ERAS with the time of initiation of postoperative chemotherapy and recovery in PD patients. Between January 1, 2008 and December 31, 2017, all patients who underwent open PD for malignant tumor at our unit were studied retrospectively. Patients were divided into ERAS and conventional groups. The time to initiation of adjuvant chemotherapy and postoperative outcomes were analyzed. There were 344 consecutive patients in this study, with 203 patients in the ERAS group. There were no significant differences between the ERAS and conventional groups in morbidity, mortality, and readmission. The median time of initiation of adjuvant chemotherapy in the ERAS group (54.1 days) was significantly shorter than that of initiation of adjuvant chemotherapy in the conventional group (67.8 days). The ERAS group had a shorter postoperative length of stay than the conventional group (14.9
