BACKGROUND: Laparoscopic liver resection for metastatic colorectal cancer (CRC) remains controversial. The objective of this study was to compare the short-term and mid-term outcomes of patients with CRC undergoing laparoscopic versus open colorectal resection with simultaneous resection for liver metastases. METHODS: A total of 126 patients underwent combined laparoscopic resection of CRC and synchronous colorectal liver metastases between 2008 and 2016. A total of 318 patients were treated by an open approach during the above period. By propensity score matching, 109 patients who underwent laparoscopic resection and 109 patients who had an open approach were compared. Analyzed variables included patient characteristics, tumor features, and short-term and mid-term outcomes. RESULTS: Demographic features and pathologic outcomes were similar in both groups after propensity score matching. Three (2.8%) patients undergoing laparoscopic liver resection experienced conversion to open procedure. There was no difference in hospital stay (p = 0.078), transfusion rate (p = 0.686), or time of bowel function return (p = 0.570) between the two groups. The laparoscopic group and the open approach group also showed similar 3-year overall survival rate (74.4% vs. 79.1%; p = 0.792) and 3-year disease-free survival rate (58.5% vs. 55.2%; p = 0.391). However, postoperative morbidity rate was significantly lower in the laparoscopic group (20.2% vs. 33.0%; p = 0.032). CONCLUSIONS: Laparoscopic colorectal resection with simultaneous resection of liver metastases showed satisfactory oncologic outcomes with some short-term advantages compared to the open approach. Thus, laparoscopic approach could be a good alternative of open approach for simultaneous liver and colon resection in patients with CRC.
