Abstract:
Objective To investigate the pathologic basis of intrahepatic biloma formed in the patients with hepatocellulr carcinoma (HCC) after interventional treatment and to assess its clinical significance. Methods Three hundreds and fifty cases of HCC were followed up with CT examination after TAE/PEI, 11 cases received percutaneous bilomography, 10 cases received percutaneous biopsy, and 1 case had surgical resection. All cases of biloma underwent external drainage of bile or ethanol ablation. Results 11 cases of biloma were found (11/350), and all of them displayed a cystic dilation (11/11), 4 cases showed a columnar dilation with indefinite border (4/11), and 3 cases accompanied with a “soft rattan sign” of intrahepatic bile ducts (3/11). The pathologic findings included necrosis on the wall of the biliary tract, extravasation of bile, and infiltration with inflammatory cells. After the external drainage or the ethanol ablation, jaundice had been decreased and symptoms relieved (9/11). Conclusions Biloma is one of the complications of the patients with HCC after TAE/PEI caused by the necrosis of the wall of biliary tract, the correct diagnosis depends on the imaging procedures and biopsy. It is helpful to the further treatment to distinguish biloma from residual nidus of carcinoma. External drainage, stent placement, and ethanol ablation may be the choice of management.
