There are doubts about the effectiveness of laparoscopic treatment of hepatic tumors and cysts. Aim: To assess the available evidence about the effectiveness of laparoscopic treatment of hepatic tumors and cysts and liver resections. Material and methods: A search in MEDLINE, EMBASE and Cochrane library databases was done, considering all studies published between 1988 and 2006. The internal validity of the evidence and global quality of the reports was assessed. Results: Thirty seven reports were included (two systematic revisions, six cohort studies and 29 case series). The quality of evidence about the effectiveness of laparoscopic treatment of hepatic cysts, when compared with the open approach, is low. Resective and non resective options are available for the laparoscopic treatment of hepatic tumors. There are no studies available comparing the effectiveness and safety of these two approaches. Laparoscopic hepatic resections have less blood loss and require a shorter hospital stay than the open approach. The available evidence on complications and mortality is scarce and of low quality. There are no studies available about the effectiveness and safety of laparoscopic hepatic resections. Conclusions: Since the evidence is scanty and low quality, no recommendations can be made about laparoscopic treatment of hepatic cysts or tumors and liver resections
