BACKGROUNDS/AIMS: Although anatomical liver resection is considered more effective in preventing complications and recurrence in hepatocellular carcinoma, its efficacy has yet to be clearly defined in colorectal cancer liver metastasis (CLM). METHODS: From January 2000 to December 2023, 145 patients underwent liver resections for CLM, divided into anatomic and non-anatomic resection cohorts. The dataset included demographic details, tumor size, number and distribution of metastases, neoadjuvant chemotherapy, primary tumor location and stage, type of liver surgery, transfusion rates, duration of hospital stay, postoperative complications, and completeness of resection. RESULTS: Of the 145 patients who underwent liver resections for metastases from colorectal cancer, 62 were in the anatomic group and 83 were in the non-anatomic group. The anatomic group had larger tumors (6.71 cm vs. 3.18 cm). Intraoperative transfusion rates were higher in the anatomic group (56.5% vs. 12.0%). Hospital stays, positive resection margin rates, and postoperative complication rates showed no significant differences. One surgery-related death occurred in the anatomic group. Disease-free and overall survival rates were comparable between groups. CONCLUSIONS: Anatomic liver resection did not demonstrate a reduction in recurrence or an improvement in survival rates compared to non-anatomic resection. As such, anatomical resection does not offer a
