HP03 LONG-TERM SURVIVAL AFTER LAPAROSCOPIC LIVER RESECTION FOR COLORECTAL LIVER METASTASES

Purpose:   Short term outcomes for laparoscopic liver resection (LLR) have been well reported in the literature, however there are few published data on long-term survival after LLR for colorectal liver metastases (CLM) and no studies have determined that the prognosis after LLR for CLM is comparable to open liver resection (OLR). Direct retrospective comparison of survival between laparoscopic versus open series is difficult due to the selection bias of the laparoscopic group. Published predictive indices in OLR enable the prediction of survival based on the patient's clinical risk score. Our aim is to determine the long term survival after LLR for CLM and to compare this to these published indices based on the patients’ clinical risk factors. Methodology:   Retrospective analysis of a prospectively maintained database. Results:   44 patients underwent LLR for CLM, including 13 right hepatectomies, 2 left hepatectomies, 16 left lateral sectionectomies and 13 non-anatomical resections. 36% had >1 tumour, 33% had a maximal tumour diameter of ≥5 cm, 61% a node positive primary and 43% a CEA >60. Median follow up was 30.8 months. 5 year survival was 46.1% (26.4–63.6%) and median survival was 46.7 months (36.3–88.6 months). Actuarial survival curves are compared to published survival curves. Conclusions:   Long-term survival after LLR for CLM is comparable to published results for OLR.
