We evaluated changes in liver function parameters and risk factors for the deterioration of liver function 12 months after percutaneous radiofrequency ablation (RFA) therapy in patients with hepatocellular carcinoma (HCC).
The subjects in this retrospective study comprised 102 patients with HCC who had undergone RFA therapy and exhibited no recurrence of HCC 12 months thereafter. Serial changes in serum total bilirubin and albumin, prothrombin time, and Child-Pugh score were evaluated before RFA and 3, 6, 9, and 12 months thereafter. Deterioration of liver function was defined when the Child-Pugh score increased by at least 2 at 12 months after RFA therapy. We determined the factors related to aggravation of liver function after RFA therapy.
Liver function had deteriorated 12 months after RFA in 29 patients (28.4%). Serum albumin levels decreased significantly from before (3.7±0.1 g/dL, mean±SD) to 12 months after RFA therapy (3.3±0.1 g/dL,
Among the liver-function parameters, serum albumin level was markedly decreased in HCC patients over the course of 24 months after RFA therapy. A pre-RFA thrombocytopenia represents a major risk factor for the deterioration of liver function.

Radiofrequency ablation (RFA) is performed as an alternative to surgical resection for primary or secondary liver malignancies. Although RFA can be performed safely in most patients, early and late complications related to mechanical or thermal damage occur in 8-9.5% cases. Hemocholecyst, which refers to hemorrhage of the gallbladder, has been reported with primary gallbladder disease or as a secondary event associated with hemobilia. Hemobilia, defined as hemorrhage in the biliary tract and most commonly associated with accidental or iatrogenic trauma, is a rare complication of RFA. Here we report a case of hemocholecyst associated with hemobilia after RFA for hepatocellular carcinoma that was successfully managed by laparoscopic cholecystectomy.
