Abstract:
Objective:To investigate the short-term outcomes of laparoscopic simultaneous resection of primary colorectal cancer and liver metastases in patients with resectable synchronous colorectal liver metastases (SCRLM).Methods:A descriptive case series study was performed. Clinicopathological data of patients with SCRLM who underwent laparoscopic simultaneous resection of colorectal cancer and liver metastases in Zhongshan Hospital between December 2015 and September 2018 were retrieved from a prospective colorectal cancer database. Perioperative presentations and short-term outcomes were analyzed.Results:A total of 53 patients were enrolled with average age of(61.7±11.3) years. Among them, 32 were male (60.4%) and 21 were female (39.6%). Twenty-five patients (47.2%) were American Society of Anesthesiologists (ASA) grade I and 28 (52.8%) were grade II. All the patients completed laparoscopic simultaneous resection without conversion. The average operation time was (320.2±114.5) min. The estimated blood loss was 150.0 (45.0-2000.0) ml, and only 2 cases (3.8%) received intraoperative transfusion. Postoperative pathologic results revealed that the average primary tumor size was (5.4±1.9) cm; 4 cases (7.5%) were T1-2 stage and 48 cases (90.6%) were T3-4 stage; 40 patients (75.5%) had lymph node metastasis; 19 (35.8%) had vascular involvement; 24 (45.3%) had neural invasion. The median number of liver metastases was 1.0 (1-8), and the average size of largest liver metastases was (3.0±1.9) cm. The median margin of liver metastases was 1.0 (0.1-3.5) cm, and only 1 case was R1 resection. The average time to the first postoperative flatus was (67.9±28.9) h, and the average time to the liquid diet was (107.0±33.8) h. The average postoperative indwelling catheterization time was (85.6±56.4) h. The average postoperative hospital stay was (9.2±4.4) d, and the average cost was (82±26) thousand RMB. No death within postoperative 30-day was found. The morbidity of postoperative complication was 32.1% (17/53) and 3 patients developed grade III to IV complications which were improved by conservative treatment. The median follow-up period was 23.2 months. During follow-up, 19 patients (35.8%) developed recurrence or metastasis, and 4 (7.5%) died. The 1- and 2-year disease-free survival (DFS) rates were 68% and 47% respectively, and the 1- and 2-year overall survival rates were 95% and 86% respectively.Conclusions:Laparoscopic simultaneous resection of primary colorectal cancer and liver metastases is safe and feasible in selected patients with SCRLM. Postoperative intestinal function recovery is enhanced, and morbidity and oncological outcomes are acceptable.
