The OSLO-COMET randomized trial compared laparoscopic and open resection for colorectal liver metastases. Liver surgery has traditionally required large incisions and can be technically demanding, so the study asked whether a minimally invasive approach could preserve oncological quality while improving recovery. In appropriately selected patients, laparoscopic resection provided comparable oncological outcomes while supporting the expected benefits of minimally invasive surgery, including a less invasive recovery profile. The findings added randomized evidence to a field previously dominated by observational series and expert experience. For surgeons, OSLO-COMET is particularly useful because selection is central to the success of minimally invasive liver surgery. Tumour location, number and size of lesions, previous treatment, liver reserve and surgeon expertise all influence whether laparoscopy is appropriate. The goal is not to force every case into a minimally invasive approach, but to select patients in whom the access strategy can be changed without compromising the oncological resection. The study helped move laparoscopic liver surgery from a technically interesting option toward an evidence-supported component of modern hepatobiliary practice. It also highlights the importance of specialist centres, advanced imaging and multidisciplinary planning when treating metastatic colorectal cancer.
