[Intraportal infusion of 5-FU and lipiodol-aclarubicin after hepatic resection for colorectal liver metastasis]. 
Fifty-five patients with hepatic metastasis from colorectal cancer underwent curative hepatic resection.  Postoperative intraportal infusion of 5-fluorouracil (500mg per day) for 14 days from 21 postoperative days (POD) and lipiodol-aclarubicin (40mg) at 35 POD was carried out in twenty-eight patients for reducing the recurrence in the remnant liver and improving the prognosis.  Twenty-seven patients had hepatectomy alone as controls.  Intraportal infusion chemotherapy did not induce any hepatotoxicity and hematologic severe abnormalities.  The cumulative survival rates for the infusion group and the control group, respectively, were 89.3% and 63.0% at 1 year; 55.2% and 43.3% at 2 year; 27.0% and 27.5% at 3 year.  The survival rate for the infusion group was significantly higher than that for the control group at 1 year (p < 0.05).  No difference of the recurrent rate in the remnant liver was found between the two groups.  It is suggested that intraportal infusion chemotherapy after curative hepatic resection for colorectal liver metastasis might improve survival rate at the early postoperative period.  Intraportal infusion chemotherapy could be an effective adjuvant therapy especially in the patients with bilateral and multiple hepatic metastasis.
