Abstract

Background & Aims: The benefits of enhanced recovery after surgery (ERAS) in patients undergoing gastrectomy have been reported in several studies; however, there is limited evidence supporting the efficacy of ERAS in clinical settings. We aimed to identify the benefits of ERAS in the clinical setting by investigating short-term surgical outcomes before and after the implementation of ERAS in patients who underwent gastrectomy.

Methods: We searched our gastric cancer database from 2008 to 2018 to identify patients who underwent gastrectomy before ERAS was implemented (2008-2009) and after the final version of ERAS was implemented (2016-2018). We enrolled 424 patients who were treated before ERAS was implemented and 565 patients who received our completed version of ERAS. After propensity score matching, each group included 219 patients, and short-term surgical outcomes were compared between the two groups.

Results: The length of hospital stay was significantly shorter in the ERAS group (8.8 vs. 11.5 days, p = 0.001), but the readmission rates were similar in the two groups, at 2.3%. There were no significant differences in morbidity, mortality, and complications of ≥ grade III between the groups. Of the complications, intra-abdominal bleeding (0% vs. 4.1%, p = 0.002) and intra-abdominal abscess (0% vs. 2.7%, p = 0.038) were significantly lower, whereas postoperative ileus was significantly higher in the ERAS group (8.6% vs. 0.5%, p < 0.001). In subgroup analyses by age, operative approach, and the extent of gastric resection, the ERAS group experienced a shorter hospital stay without increased readmission in all subgroups.

Conclusions: These results demonstrated that ERAS was associated with a 3-day reduction in hospital stay without increased readmission after gastrectomy. This study validated the benefits of ERAS in the clinical setting of gastrectomy.
