Influence of two different resection techniques of liver metastases from colorectal cancer on haematogenous tumour cell dissemination

Study hypothesis: We hypothesise that intraoperative haematogenous tumour cell dissemination could be reduced or prevented by using the anterior approach technique in resection of colorectal liver metastases.
Please note that as of 11/02/2009 this record was updated to include an amended end date. The initial end date at the time of registration was:
Initial anticipated end date: 28/02/2009
Primary outcome(s): To compare the anterior approach to the conventional technique of hepatic resection for colorectal metastases with respect to the incidence of intraoperative haematogenous tumour cell dissemination. We hypothesise that intraoperative haematogenous tumour cell dissemination could be reduced or prevented by using the anterior approach technique in resection of colorectal liver metastases.
