Background : Synchronous presentation of liver metastases at the time of diagnosis of the primary tumor occurs in approximately 20% of patients and is associated with worse clinical outcomes. Metastatic liver tumors are resectable in 10 to 20% of cases. Simultaneous primary cancer and liver metastases resection is a treatment of choice in selected patients. The aim of this report was to present our initial experiences of simultaneous surgery performed laparoscopically.

Methods : A single-center, retrospective report of 8 cases of laparoscopic simultaneous resection of colorectal cancer and liver metastasеs was carried out.

Results : The average patients` age was 60 years old (range, 35–74 years) and average body mass index was 28.2 kg/m2 (range, 26.3–30.0 kg/m2). The primary tumor was right-sided colon in 2 cases, left-sided colon in 4 cases, and rectal cancer in 2 cases. 6 patients presented with single-lesion liver metastasis and 2 patients presented with two lesions metastases, the majority of metastatic tumors were subсapsular. The mean operating time was 303 minutes (range, 130–500 minutes) and blood loss was 340 mL (range, 150–500 mL). The mean hospital stay was 7.5 days (range, 5–11 days). One patient developed delayed gastric emptying grade A and one patient developed biloma, which was not clinically significant.

Conclusions : This report shows that simultaneous laparoscopic resection of primary colorectal cancer and liver metastases is safe, technically feasible in selected patients and has a high cost-effectiveness.
