The current study aimed to assess the performance of the 3-level complexity classification that stratified liver resection procedures into 3 complexity grades (grade I, low; grade II, intermediate; and grade III, high complexity) and to evaluate whether the Enhanced Recovery after Surgery (ERAS) protocol improves postoperative outcomes for each complexity grade. Consecutive patients undergoing open liver resection and laparoscopic liver resection at Lausanne University Hospital during 2010 to 2020 were assessed. A total of 437 patients were included. Operative time, estimated blood loss, and length of hospital stay increased significantly, with a stepwise increase of the grades from I to III in open liver resection and laparoscopic liver resection (all, p < 0.05). The same trend for Comprehensive Complication Index was found in open liver resection (p < 0.005). Age (p= 0.004), 3-level complexity classification (grade II vs I; p= 0.001; grade III vs I; p < 0.001), no use of the ERAS protocol (p=ccording to surgical complexity and patient age to improve outcomes after liver resection. High scores in the Medically Necessary, Time-Sensitive (MeNTS) scoring system, used for elective surgical prioritization during the coronavirus disease 2019 pandemic, are assumed to be associated with worse outcomes. We aimed to evaluate the MeNTS scoring system in patients undergoing elective surgery during restricted capacity of our institution, with or without moderate or severe postoperative complications. In this prospective observational study, MeNTS scores of patients undergoing elective operations during May and June 2020 were calculated. Postoperative complication severity (classified as Group Clavien-Dindo < II or Group Clavien-Dindo ≥ II), as well as Duke Activity
