Brief Summary
Biliary obstruction is importantly influencing quality of life and survival of patients suffering from primary or secondary bile duct malignancies. The aim of this retrospective data analysis is to evaluate endoscopic radiofrequency ablation (RFA) with the HabibTM EndoHBP catheter for the treatment of malignant biliary obstruction. RFA procedures performed in Austria so far will be analyzed with regard to feasibility and safety of the technique. Therefore, the following parameters will be assessed: (among others) technical failures during the RFA procedure, complications during the RFA procedure, hospital stay, adverse events during hospital stay and until first clinical control after discharge (an expected average of 4 weeks after RFA procedure), 30-day and 90-day mortality. The results of this study should help to better understand important aspects of biliary RFA which may positively influence future applications of this method.

Outcome Measures
Primary Outcomes (1)
Number of RFA-procedures with technical failures
The technical feasibility in this study will be specified as ratio of all technically successful RFA-applications to all examinations in which RFA-use was intended. A RFA-application will be classified as technically successful if it is possible to introduce the RFA-catheter into the biliary system, place it adequately accross the malignant stricture, apply RFA-energy and withdraw the RFA-catheter after RFA-application.
During the respective RFA-examination (an expected average of 1 hour)
Secondary Outcomes (1)
Number of patients with interventional complications
During the respective RFA-procedure (an expected average of 1 hour)
Other Outcomes (3)
Hospital stay
Inpatient stay after RFA-procedure (an expected average of 5 days)
Number of patients with Adverse events as a Measure of Safety and Tolerability
During hospital stay and until first clinical control after discharge (an expected average of 4 weeks after RFA procedure)
Mortality
30 days and 90 days after RFA-procedure (calculating 30- and 90-day mortality rate), assessed retrospectively by screening clinical reports (including death reports) of the study patients on average 1 year after RFA-procedure
Study Arms (1)
Malignant biliary obstruction
EXPERIMENTALAll patients who underwent endoscopic radiofrequency ablation with the HabibTM EndoHBP as a treatment for malignant biliary obstruction in Austria between November 2010 and December 2012.
Interventions
Endoscopic radiofrequency ablation with the HabibTM EndoHBP catheter uses bipolar electrical energy for tissue coagulation and can be applied without any special patient preparation in the context of an endoscopic retrograde cholangiopancreatography (ERCP) examination to treat malignant biliary strictures.
ERCP is used to guide the RFA-catheter under radiological control to the location of the malignant stricture.
Used to apply radiofrequency energy to the malignant biliary stricture (see also intervention "endoscopic radiofrequency ablation")
