Does Laparoscopic Liver Resection Have Greater Incidence of Bile Leak Compared to the Open Approach?

1.1. Background: Biliary leak is the most frequent complication in liver resections. The Second International Consensus Conference mentions a potentially higher incidence of bile leaks in Laparoscopic Liver Resection (LLR) that still needs to be evaluated. The objective of the study is to compare the incidence of bile leaks, using the definition of IGSLL, between open liver resection (OLR) and LLR in a center with the same technique of dividing the parenchyma for both laparoscopic and open surgery.
