After the Original Review entitled "Laparoscopic liver resection: a review of current indications and surgical techniques" (1) was accepted for publication in February, 2018 by HBSN, several important studies were published to update the advances in laparoscopic liver resection (LLR). Therefore, we consider it necessary to make a supplement. Fretland et al. (2) conducted a randomized controlled trial to compare laparoscopic and open liver resection (OLR) for colorectal liver metastasis, which might be the first accomplished large-scale RCT on LLR. A total of 280 patients were included, among whom 133 patients received LLR while others received open procedure. LLR was found to be associated with less postoperative complications and more cost-effective, while the rate of free resection margins did not significantly differ. This provides high level and encouraging evidence to support LLR implementation.
