Long-term outcomes of modified enhanced recovery after surgery (mERAS) protocols in peri-operative management of minimally invasive esophagectomy.

Background: Enhanced recovery after surgery (ERAS) programs consist of multimodal, evidence-based protocols implemented during the pre-, intra-, and postoperative periods to reduce perioperative stress, minimize complications, accelerate recovery, and shorten hospital stays. While ERAS has been associated with improved long-term outcomes in gastric, colon, and rectal cancers, its impact on the long-term prognosis of esophageal cancer remains unclear due to limited high-volume studies. Methods: This retrospective clinical study included 230 consecutive patients with esophageal carcinoma who underwent esophagectomy between June 1, 2017 and March 30, 2019. The patients were divided into two groups: the mERAS group, managed according to modified ERAS (mERAS) protocols, and the standard care (SC) group, receiving standard perioperative care. Postoperative outcomes, including morbidity, functional recovery, and hospital stay length, were compared between the groups. Additionally, the influence of mERAS protocols on long-term survival was assessed, particularly in patients with significant preoperative weight loss. Results: Baseline characteristics were comparable between the two groups, except for a higher prevalence of cardiac disease or hypertension in the mERAS group (25.0% Conclusions: mERAS protocols improve recovery and reduce complications in esophageal cancer patients undergoing minimally invasive esophagectomy, with survival benefits in those with significant preoperative weight loss.
