During recent years we saw over the world a consistent growth of laparoscopic liver surgery (LLS), essentially due to progress of the surgical techniques, technology and diagnostic imaging. During the Louisville conference on LLS (2008) the technique was thoroughly described and defined. One of the most important statements was the promotion of national registries, taking into account the logistics and feasibility problems of randomized trials in this setting. The main purpose to hold a Belgian national registry is to define the role of LLS in our country, looking for short and long-term outcomes, especially in case of liver tumors.
