Background And Objectives:
Hepatic cryotherapy is a method of in situ cytodestruction used for unresectable liver tumours that can be combined with regional cytotoxic administration. We have used intra-arterial chemotherapy with 5-fluorouracil (5-FU) after hepatic cryotherapy but changed to 5-fluorodeoxyuridine (FUDR) because of the arterial toxicity of 5-FU. A new complication was seen.
Methods:
A retrospective case note study was performed of 130 patients who had undergone hepatic cryotherapy followed by regional chemotherapy at our centre. Seven patients received FUDR; 123 received 5-FU.
Results:
Biloma at the cryotherapy sites was seen in three patients in the FUDR group; two other patients in this group had other types of hepatic collection. Our previous experience with intra-arterial 5-FU in 123 patients after hepatic cryotherapy showed no evidence of this syndrome.
Conclusions:
Intra-arterial FUDR should not be used after hepatic cryotherapy, at least during the immediate postoperative period.
