To compare early and long-term outcomes in patients undergoing resection for colorectal liver metastases (CLM) by either a laparoscopic (LA) or an open (OA) approach.The LA is still a matter of debate regarding the surgical management of CLM.Data of all patients from 32 French surgical centers who underwent liver resection for CLM from January 2006 to December 2013 were collected. Aiming to obtain 2 well-balanced cohorts for available variables influencing early outcome and survival, the LA group was matched 1:1 with the OA group by using a propensity score (PS)-based method.The unmatched initial cohort consisted of 2620 patients (LA: 176, OA: 2444). In the matched cohort for operative risk factors (LA: 153, OA: 153), the LA group had shorter hospitalization stays [11.1 (±9) days vs 13.9 (±10) days; P = 0.01] and was associated with lower rates of grade III to V complications [odds ratio (OR): 0.27, 95% confidence interval (CI) 0.14-0.51; P = 0.0002] and inhospital transfusions (OR: 0.33 95% CI 0.18-0.59; P < 0.0001). On a prognostic factors well-balanced population (LA: 73, OA: 73), the LA group and the OA group experienced similar overall (OS) and disease-free (DFS) survival rates [OS rates of 88% and 78% vs 84% and 75% at 3 and 5 years, respectively (P = 0.72) and DFS rates of 40% and 32% vs 52% and 36% at 3 and 5 years, respectively (P = 0.60)].In the patients who are suitable for LA, laparoscopy yields better operative outcomes without impairing long-term survival.
