Incidence and clinical impact of bile ducts changes after multibipolar radiofrequency ablation for hepatocellular carcinoma.

• Bile duct changes are frequently observed after multibipolar radiofrequency ablation for hepatocellular carcinoma, occurring in 33% of cases in our study. • Patients with bile duct changes exhibited a higher increase in bilirubin levels at 6 months but no more cirrhosis decompensation or liver abscesses. • Biliary changes following multibipolar radiofrequency ablation for hepatocellular carcinoma are not alarming and do not necessitate any specific monitoring or intervention.
