Summary
Brief summary (as posted)
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.

- label
- Malignant biliary obstruction
- description
- All 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.
- interventionNames
- Procedure: Endoscopic radiofrequency ablation
- Procedure: Endoscopic retrograde cholangiopancreatography (ERCP)
- Device: HabibTM EndoHPB catheter
Primary outcomes (1)
- measure
- Number of RFA-procedures with technical failures
- timeFrame
- During the respective RFA-examination (an expected average of 1 hour)
- description
- 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.
