To study the clinical effect of laparoscopic radical resection of colorectal cancer combined with laparoscopic resection for the treatment of liver metastasis of colorectal cancer.

The data of 90 patients with synchronous colorectal cancer liver metastases from January 2014 to December 2015 were retrospectively analyzed. The subjects were divided into laparoscopic group (n=45) and open group (n=45). SPSS21.0 statistical soft data analysis was used. Intraoperative and postoperative indicators were used (±s), independent t test. χ² test was used for the postoperative complications. The skewed distribution data are represented by M (Qn) and M. Use Mann-Whitney U test. The difference was statistically significant in P<0.05.

There was no significant difference in operative time, intraoperative blood loss, intraoperative blood transfusion, nerve infiltration and vascular invasion between the two groups (P>0.05). Postoperative condition: There was no significant difference in eating time, postoperative TBIL, postoperative ALT, complications and length of stay between the two groups (P>0.05). The time of admission to ICU in laparoscopic group was (2.1±1.6) d, which was significantly shorter than that in laparotomy group (1.0±06) d (t=1.804, P<0.05). Follow up: there was no significant difference in cumulative tumor free survival and survival time between the two groups in 1 and 2 years after operation (P>0.05).

Laparoscopic radical resection of colorectal cancer combined with laparoscopic hepatectomy is safer than laparoscopic radical resection of colorectal cancer combined with open hepatectomy, but the two treatment methods have the same effect in postoperative complications and clinical prognosis.
