Technology Status Evaluation Reports

Technology status evaluation reports provide a review of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Reports are based on an evaluation of medical literature and a search of the MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database to identify the reported adverse events of a given technology. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided. Technology status evaluation reports are scientific reviews based on expert consensus and are provided solely for educational and informational purposes.

The members of the ASGE Technology Committee provide ongoing conflict of interest (COI) disclosures throughout the development and publication of all documents in accordance with the ASGE Policy for Managing Declared Conflicts of Interests.

If you have any questions or suggestions, please contact Customer Support at Info@asge.org.

The following information is intended only to provide general information and not as a definitive basis for diagnosis or treatment in any particular case. It is very important that you consult your doctor about your specific condition.

Background Radiofrequency ablation (RFA) uses thermal energy to accomplish targeted tissue destruction. Within the GI tract, RFA was initially studied for the treatment of dysplastic Barrett’s esophagus (BE), and this continues to be a common application. Indications for RFA within the GI tract continue to evolve. It has been used in the treatment of esophageal squamous cell dysplasia, gastric antral vascular ectasia (GAVE), radiation proctopathy, cholangiocarcinoma, and pancreatic neoplasia, among other conditions.1, 2, 3, 4, 5, 6, 7, 8, 9 This report focuses on devices and techniques used to perform RFA in the GI tract. Technology under review RFA devices use an electrosurgical generator connected to bipolar electrode arrays to deliver thermal energy to tissue. Electricity travels through tissue between alternating positive and negative poles along the electrode arrays of the RFA device in the radiofrequency range of 450 to 500 kHz. This current generates thermal energy within tissue in direct contact with the radiofrequency (RF) electrode, resulting in coagulation necrosis of the targeted tissue. The spacing and geometry of the electrodes on the RFA device and the preset parameters (energy, power) within the RFA generator allow achievement of a consistent depth of ablation. For instance, in the treatment of mucosal pathologic conditions, the dosimetry is designed to yield an ablation depth to the muscularis mucosae (700-800 μm deep).10, 11
