Modified Enhanced Recovery Program in Emergency Surgery (MERES)
Modified Enhanced Recovery Program in Emergency Surgery (MERES)
Laparoscopic appendectomy (LA) is a widespread surgical procedure. Patients may develop
 considerable postoperative pain and dyspepsia resulting in prolong in-hospital stay. Almost
 10% of patients develop postoperative complications. Enhanced recovery after surgery (ERAS)
 program has proven its effectiveness in elective surgery and can theoretically improve
 outcomes of LA. To date there is no ERAS program for LA. The aim of the study was to
 investigate the safety and efficacy of a modified ERAS protocol in LA.
A modified ERAS (mERAS) protocol was investigated. The study is a prospective, randomized
 nonblinded. All patients underwent LA. Modified ERAS protocol included patient informing,
 limitation of drainage use; intraperitoneal anesthesia with long-acting anesthetics;
 low-pressure pneumoperitoneum; early mobilization and oral nutrition. Pain level was assessed
 in rest using visual analogue scale (VAS). The primary endpoint was postoperative length of
 stay (pLOS).
