Background Minimally invasive liver resections for metastatic colorectal cancer have been increasingly performed all over the world with promising results. We planned the current study to review our experience on this matter and compare short- and long-term outcomes of laparoscopic liver resection (LLR) and open liver resection (OLR) in patients with colorectal cancer liver metastasis (CRLM). Materials and methods This is a single-center retrospective analysis of patients with CRLM who underwent laparoscopic (n=86) and open (n=96) surgical treatment for metastatic liver lesions between March 2016 and November 2022. Tumor characteristics, intra- and postoperative results, overall survival (OS), and disease-free survival (DFS) were analyzed and compared. Results LLR was associated with significantly shorter surgery duration (180 minutes versus 295 minutes, p=0.03). There was no significant difference in blood loss between the two groups (100 mL versus 350 mL, p=0.061). Additionally, the laparoscopic approach was associated with significantly shorter hospital stays (6 days versus 9 days, p=0.004). The rate of major complications (Clavien-Dindo classification ≥ 3) was lower in the LLR group (5.8% versus 16.6%, p=0.037). There was no mortality in the LLR group, and in the OLR group, one lethal case was induced by mesenteric thrombosis on the fifth postoperative day. We did not find a statistically significant difference in the OS rate between the two groups at one, three, and five years: 97.3%, 74.7%, and 43.4%, respectively, in the OLR group and 95.1%, 70.3%, and 49.5%, respectively, in the LLR group (p=0.53). DFS at one, three, and five years were 88.7%, 52.3%, and 25.5%, respectively, in the LLR group and 71.9%, 53.1%, and 19.3%, respectively, in the OLR group (p=0.66). Conclusions This study showed that laparoscopic liver surgery is a safe and effective method of CRLM treatment in our center. LLR was associated with a decrease in major morbidity, shorter surgery duration, and reduced postoperative hospital stay. Minimally invasive liver resections showed similar oncological outcomes to the open approach in terms of overall and disease-free survival.
