Bile Leakage after Laparoscopic and Open Liver Resection; Incidence and Clinical Impact: An International Multicenter Propensity Score-Matched Study of 13,379 Patients

Despite many developments, postoperative bile leakage (POBL) remains a relatively common postoperative complication after laparoscopic liver resection (LLR) and open liver resection (OLR). Previous studies regarding the incidence and clinical impact of POBL have mainly focused on patients undergoing OLR. The aim of this study is to compare the incidence and clinical impact of POBL between patients undergoing LLR and OLR in a large international multicenter cohort using a propensity score matched analysis.
