ERCP With SEMS Plus Radiofrequency Ablation
Endoscopic retrograde cholangiopancreatogram (ERCP) is performed under standard conditions with cannulation of the bile duct, and demonstration on a cholangiogram the location, diameter and length of the biliary stricture. The HabibTM EndoHBP probe (EMcision, London, United Kingdom) is advanced through the working channel of a side viewing endoscope over a 0.035in guidewire, and positioned across the occluded SEMS under fluoroscopy. 7-10W are usually delivered for 90 seconds with a standard high frequency generator, followed by a 1 minute resting period. Sequential applications of RFA are applied along the entire length of the stricture with an overlap of 1cm. ERCP with SEMS plus radiofrequency ablation
