Background
The safety and efficacy of laparoscopic liver resection (LLR) for colorectal liver metastasis (CLM) remain to be established. A meta-analysis was undertaken to compare LLR and open liver resection (OLR) for CLM with respect to surgical and oncologic outcomes.
Methods
An electronic search was performed to retrieve all relevant articles published in the English language by the end of March 2013. Data were analyzed using Review Manager version 5.0.
Results
A total of 8 nonrandomized controlled studies with 695 subjects were analyzsed. Intra-operative blood loss, the proportion of patients requiring blood transfusion, morbidity and the length of hospital stay were all significantly reduced after LLR. Postoperative recurrence, 5-year overall and disease-free survivals were comparable between two groups.
Conclusions
LLR for CLM is safe and efficacious. It improves surgical outcomes and uncompromises oncologic outcomes as compared with OLR.
