Modified protocol for Enhanced Recovery After Surgery is beneficial for achalasia patients undergoing peroral endoscopic myotomy: a randomized prospective trial

INTRODUCTION: Enhanced Recovery After Surgery (ERAS) protocols have been proven to promote postoperative recovery. However, limited evidence is available on ERAS protocols in patients undergoing peroral endoscopic myotomy (POEM). AIM: To study the safety and effectiveness of an ERAS protocol in terms of the standard postoperative length of stay (LOS) and QoR-15 (Quality of Recovery) score of patients undergoing POEM. MATERIAL AND METHODS: Eighty patients were randomly divided into the ERAS or conventional group. The ERAS group received ERAS management, while the conventional group received normal management. The ERAS protocol included sufficient preoperative education, shortening time of preoperative fasting, maintaining intraoperative normothermia, intraoperative fluid management, and improving analgesia. We compared the results between the two groups in term of standard postoperative LOS and cost, QoR-15 score, postoperative pain and complications. RESULTS: Patients showed an improvement in the ERAS group in terms of earlier readiness for hospital discharge (40.21 ±8.42 h vs. 48.63 ±10.42 h; p < 0.001), earlier resumption of oral feeding (31.80 ±8.7 h vs. 42.35 ±10.80 h; p < 0.001), lower VAS, and higher QoR-15 score (139.29 ±2.21 vs. 137.03 ±3.77; p = 0.002) on postoperative day 2. For post-operative complications, there was no significant difference between the two groups. CONCLUSIONS: The ERAS protocol is feasible and safe for POEM, and may decrease standard postoperative LOS, shorten recovery of gastrointestinal function, and improve postoperative patient satisfaction.
