Objective:
To explore a new approach to the management of malignant biliary obstruction using percutaneous transhepatic biliary radiofrequency and endoprothesis.
Methods:
Percutaneous transhepatic biliary radiofrequency and endoprothesis were performed in 2 cases of malignant biliary obstruction, including 1 of hilar cholangiocarcinoma and 1 of pancreatic head carcinoma. The tumor was ablated with radiofrequency followed by placement of matched metal stents into the biliary duct.
Results:
The surgical procedures were carried out smoothly in the 2 cases. The symptoms of the patients were obviously improved after the operation with a significant decrease in the serum levels of total bilirubin, and CA-199 level decreased to the normal level in 1 case.
Conclusions:
This new approach is safe for management of malignant biliary obstruction. Compared with the more conventional interventional therapy, radiofrequency can reduce the intraoperative bleeding and arrest the local tumor growth to promote the patency of the stent as well as the postoperative survival of the patients.
