Survival analyses after hepatectomy for colorectal liver metastases (CRLM) mostly address tumorrelated factors; this study has simultaneously evaluated interventional factors which may be influenced by the surgeon.

Operative and longterm results of 251 consecutive patients undergoing hepatectomy for CRLM between 1992 and 2007 were analyzed.

Mortality was 0.8%, morbidity 22.9%, intraoperative blood transfusion rate 23.1% (19.4% with pedicle clamping, 35.0% without clamping, P = 0.01), R0resection 93.6% (2/3 with tumorfree margin >5 mm). The 3, 5, 10year overall and diseasefree survival rates were 55.2%, 38.9%, 24.2%, and 37.1%, 28.2%, 25.4%. Univariate analysis: lower survival was related to transfusion requirement, tumor size >5 cm, tumorfree margin ≤5 mm, major hepatectomy, R1resection, multiplicity of CRLM, preoperative …
