Techniques and innovations in liver surgery

Since the development of laparoscopic cholecystectomy in 1987, the laparoscopic approach extended to several abdominal procedures. However, liver laparoscopic approach remains during a long time limited, contrarily to abdominal surgery. It is mainly due to the technical complexity of interventions, the lack of appropriate instrumentation, the risk of gas embolism, of uncontrolled bleeding, the difficulty to detect intra-operatively in real time the tumour, the fear of not being able to follow oncological principles with a subsequent risk of tumoral dissemination.
