Synchronous resections of primary colorectal tumor and liver metastasis by laparoscopic approach

World J Hepatol. 2013 Jun 27;5(6):298-301. doi: 10.4254/wjh.v5.i6.298.

Abstract

Liver metastasis of colorectal cancer is common. Resection of solitary tumors of primary and metastatic colorectal cancer can have a favorable outcome. Open resection of primary colorectal tumor and liver metastasis in one operation or in separate operations is currently common practice. Reports have shown that synchronous resections do not jeopardize short or long-term surgical outcomes and that this is a safe and effective approach in open surgery. The development of laparoscopic colorectal surgery and laparoscopic hepatectomy has made a minimally invasive surgical approach to treating colorectal cancer with liver metastasis feasible. Synchronous resections of primary colorectal tumor and liver metastasis by laparoscopy have recently been reported. The efficacy and safety of laparoscopic colorectal resection and laparoscopic hepatectomy have been proven separately but synchronous resections by laparoscopy are in hot debate. As it has been shown that open resection of primary colorectal tumor and liver metastasis in one operation results in an equally good short-term outcome when compared with that done in separate operations, laparoscopic resection of the same in one single operation seems to be a good option. Recent evidence has shown that this new approach is a safe alternative with a shorter hospital stay. Large scale randomized controlled trials are needed to demonstrate the effectiveness of this minimally invasive approach.
