Acute cholecystitis associated with hepatic arterial infusion of floxuridine

In a 1 year period, 13 patients underwent pump implantation for liver metastasis from a primary colorectal tumor. The gallbladders were not removed at the time of pump implantation in the initial six patients. In these patients, chemotherapy consisted of floxuridine given every 2 weeks followed by a 2 week rest period and cisplatin over 1 hour by way of the side portal on day 8 of the cycle. The treatment was repeated every 28 days. All patients whose gallbladders were not removed at the time of pump implantation required reoperation for acute or chronic acalculous cholecystitis from 1 to 9 months (mean 5.4 months) after pump implantation. At operation, all patients were found to have various degrees of inflammation and fibrosis. In one patient, significant sclerosing cholangitis was documented that involved the entire intrahepatic ductal system and hepatic duct bifurcation. Cholecystectomy and operative cholangiography are recommended in all patients who undergo pump implantation for metastatic disease to the liver.
