Simultaneous Laparoscopic Resection of Primary Colorectal Cancer and Metastatic Liver Tumor: Initial Experience of Single Institute

Abstract

Approximately 20%-25% of patients with colorectal cancer have synchronous liver metastasis at the time of diagnosis. Simultaneous resection of primary colorectal cancer and metastatic liver tumor is the treatment option in colorectal cancer with liver metastasis. The aim of this study was to report our initial experiences of simultaneous laparoscopic resection of colorectal cancer and liver metastasis. A single-center, retrospective study of 10 cases of laparoscopic simultaneous resection of colorectal cancer and liver metastasis was carried out. The patients' average age was 63.7 years (range, 48-75 years) and average body mass index was 23.5 kg/m2(range, 20-27.4 kg/m2). The primary cancer was right-sided colon cancer in 4 cases, left-sided colon cancer in 3 cases, and rectal cancer in 3 cases. Single-lesion liver metastasis was found in 6 cases and two or more lesion liver metastasis was found in 4 cases. The mean operating time was 401 minutes (range, 230-620 minutes) and blood loss was 500 mL (range, 60-1000 mL). The mean hospital stay was 10 days (range, 7-15 days). One case was converted to open surgery and anastomotic leakage was encountered in the converted case. This study shows that simultaneous laparoscopic resection of primary colorectal cancer and liver metastasis is safe and technically feasible in selected patients.
