title: Laparoscopic surgery of liver tumors.
abstract: BACKGROUND
  Despite initial concerns regarding safety and oncological adequacy, the use of laparoscopic liver resections for benign and malignant diseases has spread worldwide. As in open liver surgery, anatomical orientation and the ability to control intraoperative challenges as bleeding have to be combined with expertise in advanced laparoscopic techniques.
  
  
  METHODS
  In this review, we provide an overview regarding the literature on laparoscopic liver resection for benign and malignant liver tumors with the aim to discuss the current standards and define remaining challenges. Although numerous case series and meta-analyses have addressed the evolving field of laparoscopic liver surgery recently, data from randomized controlled trials are still not available.
  
  
  CONCLUSIONS
  Laparoscopic liver resection is feasible and safe in selected patients and experienced hands. Even major liver resections can be performed laparoscopically. The minimal invasive approach offers benefits in perioperative short-term outcome without compromising oncological outcomes compared to open liver resections. Further randomized trials are needed to formally prove these statements and to define the optimal indication and techniques for the individual patient.
