Outcomes of laparoscopic hepatic resection for colorectal cancer metastases.

The role of laparoscopic liver resection for cancer remains controversial. This review summarizes the expanding literature on outcomes of minimally invasive hepatic resection for colorectal cancer liver metastases. Four recent studies (in more than 300 patients) show 5-year overall-survival rates of 46-64%, which are comparable to results in modern open hepatic resection series. The advantages of laparoscopic liver resection include smaller incisions, less pain, less narcotic requirements, and shorter length of stay.
