The Korean Enhanced Recovery After Surgery (ERAS) Committee within the Korean Society of Surgical Metabolism and Nutrition was established to develop ERAS guidelines tailored to the Korean context. This guideline focuses on creating the most current evidence-based practice guidelines for ERAS purposes, based on systematic reviews. All key questions targeted randomized controlled trials exclusively, and if fewer than 2 were available, studies employing propensity score matching were also included. Recommendations for each key question were marked with strength of recommendation and level of evidence following internal and external review processes by the committee.

Purpose: Few studies have analyzed the effects of preoperative pain education on the postoperative decision to discharge. The purpose of this study was to determine the effects of pain education and management on the decision to discharge patients after single-incision laparoscopic appendectomy (SILA).Methods: We analyzed 135 patients who had undergone SILA for acute appendicitis between March 2017 and April 2018 in a single medical center. Of these, 72 patients (53.3%) had received preoperative pain education (group 1), and 63 (46.7%) had not (group 2). We compared perioperative outcomes and complications between the groups.Results: Baseline characteristics of sex, age, body mass index, American Society of Anesthesiologist score, and systemic inflammation factors (neutrophil-lymphocyte ratio, C-reactive protein level) did not differ significantly between the groups. There were no postoperative complications for patients in either group. Perioperative consequences and pathologic findings were not significantly different between the groups; however, length of hospital was significantly shorter in group 1.Conclusion: Preoperative pain education in relation to postoperative pain management influenced the decision to shorten the postoperative hospital length of stay after SILA.
