No significant differences in the rate of complication were found between the study and control groups. PFS of CRLM in laparoscopic, intraoperative CEUS, and laparoscopic CEUS groups are all longer than their control groups. Complete ablation rates of laparoscopic, intraoperative CEUS, and laparoscopic CEUS groups are all higher than in their control groups with statistical significance. A tumor size of 2.15\u2009cm is determined to be the optimal cut\u2010off with the area under the ROC curve of 0.854, 95% CI (0.764, 0.944), <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001.
