Probability of Postoperative Complication after Liver Resection: Stratification of Patient Factors, Operative Complexity, and Use of Enhanced Recovery after Surgery

BACKGROUND: 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. STUDY DESIGN: Consecutive patients undergoing open liver resection and...
