New ePTFE/FEP-covered stent in the palliative treatment of malignant biliary obstruction.
To determine the technical efficacy and safety of an expanded polytetrafluoroethylene and fluorinated ethylene propylene (ePTFE/FEP)-covered metallic stent in the management of malignant biliary obstruction and to evaluate its clinical efficacy by estimating stent patency and patient survival rates. ⋯ Preliminary results suggest that placement of this ePTFE/FEP-covered stent is feasible and effective in achieving biliary drainage. The percentage of patients undergoing lifetime palliation and the midterm patency are promising. However, the incidence of acute cholecystitis is high. Treatment of a larger group of patients is mandatory to validate these long-term results.

Endovenous obliteration with radiofrequency-resistive heating for greater saphenous vein insufficiency: a feasibility study.
To assess the feasibility, safety, and clinical utility of ultrasound (US)- and fluoroscopy-guided endovenous saphenous vein obliteration with radiofrequency (RF)-resistive heating in the treatment of primary venous insufficiency. ⋯ Endovenous obliteration employing RF-resistive heating is a relatively safe and promising minimally invasive technique for the treatment of primary GSV insufficiency.
