To evaluate the safety and short-term prognosis of four surgical methods for colorectal cancer with liver metastasis.

A retrospective analysis of the case data of 101 patients with colorectal cancer with liver metastases admitted from May 2016 to November 2018 was divided into 4 groups according to different surgical procedures, namely group A (24 cases, laparoscopic surgery at the same time) and group B (26 cases, simultaneous open surgery), group C (22 cases, staged laparoscopic surgery) and group D (29 cases, staged open surgery). SPSS 23.0 statistical analysis software was used. Surgery-related indicators are expressed as (±s), independent sample t tests were used between the two groups, and one-way analysis of variance between multiple groups; postoperative complications, survival rates, and recurrence rates are compared by χ² test; The cumulative survival rates were compared using log-rank test. P<0.05 was considered statistically significant.

The operation time and intraoperative bleeding volume of the four groups were group A<group C<group B<group D, and the differences were statistically significant (P<0.05); the total hospital stay of group A<group B<group C<group D(P<0.05); There was no significant difference in the total complication rate, 2-year survival rate and recurrence rate between the four groups (P>0.05).

Concurrent laparoscopic surgery for patients with liver metastases of colorectal cancer is safe and feasible, and the risk of postoperative complications does not increase, but has no significantly help in improving prognosis.
