Short-Term and Long-Term Outcomes After Simultaneous Resection of Colorectal Malignancies and Synchronous Liver Metastases

Background We evaluated the simultaneous resection of colorectal malignancies and synchronous liver metastases. Methods Between June 1982 and June 2006, a total of 752 patients underwent resection of colorectal hepatic metastases. In all, 185 (25%) of them underwent simultaneous resection of the hepatic lesions and the corresponding primary tumors. Results The median hospital stay was 8 days (range 4–24 days), with a median operating time of 4 h (range 2–8 h). Altogether, 62 (33.5%) patients required intraoperative transfusion of packed red blood cells (median 2.1 IU, range 1–5 IU), and 25 (13.5%) were given frozen fresh plasma (median 2.1 IU, range 1–4 IU). The morbidity rate was 20.5%. There were two postoperative deaths (mortality rate 1.08%) within 30 days of the surgical intervention. Major hepatectomy was associated with greater morbidity (37.2% vs. 16.2%, P
