Abstract

Background: Safety and efficacy of simultaneous resections for patients with colorectal cancer and synchronous liver metastases have been widely reported, while the topic of approach (laparoscopic or open) to hepatic and colorectal resection is still a debated issue. The aim of this study was to assess short-term outcome of combined resection of left colon or rectum cancer and liver metastases, comparing the results of the primary tumor resection performed by laparoscopic or open approach. Study design: From January 2004 to March 2014, 106 patients underwent combined resection of colorectal cancer and synchronous liver metastases. Sixty-nine patients underwent laparoscopic colorectal resection (laparoscopic colorectal surgery, LCS Group), and were compared with 37 patients undergoing colorectal resection by laparotomy (totally open surgery, TOS Group). Hepatic resection was performed by open approach in all the patients. Results: Groups were comparable in terms of patients and disease characteristics, extent of liver resection, and length of surgery. In LCS Group, blood loss (400 vs. 650 mL, p <0.001) and rate of intraoperative transfusions (19.3 vs. 47.2 %, p = 0.04) were lower compared to TOS Group. LCS Group was associated with reduced postoperative morbidity (24.6 vs. 44.4 %, p = 0.039), and shorter postoperative median hospital stay (9 vs. 13 days, p <0.001). LCS and TOS Groups had comparable oncologic radicality in terms of primary tumor lymphadenectomy (median number of removed nodes 19 and 20, respectively, p NS) and rate of R1 colorectal resections (two patients in both Groups). Multivariate analysis revealed significant correlation morbidity with preoperative chemotherapy, blood loss, and approach to primary tumor. Conclusions: Laparoscopic resection of colorectal cancer in patients undergoing simultaneous open resection of liver metastases is associated with a reduction of blood loss, morbidity, and postoperative hospital stay, without affecting oncologic radicality. Outcome is mainly conditioned by approach to intestinal surgery, rather than the extent of liver resection.
