ASGE 2023 Masterclass EUS: Principles, Best Practices & Innovative Paradigms (Virtual) | February 2023-EUS Ablation: Are We There Yet?

Video Transcription

Video Summary

In this video, the speaker discusses the technique of endoscopic ultrasound (EUS) guided ablation therapy, specifically focusing on ethanol injection and radiofrequency ablation (RFA) for pancreatic tumors. The speaker explains the indications for ethanol injection, which include functional neuroendocrine tumors or insulinoma, non-functional neuroendocrine tumors larger than two centimeters in patients who are not fit for surgery or refuse surgery. They also discuss the technique for ethanol injection, emphasizing the importance of confirming the hypervascular nature of the tumor with contrast-enhanced EUS before injecting alcohol into the tumor. The speaker also shares data on the efficacy and adverse events of ethanol injection. The speaker then moves on to discuss RFA as an alternative ablation therapy and describes the steps involved in RFA, including checking the lesion with contrast-enhanced EUS, advancing the RFA needle into the tumor, and delivering energy to ablate the tumor tissue. The speaker also discusses the adverse events and follow-up protocol for RFA and presents data on the clinical success and adverse events of RFA in pancreatic tumors. The video concludes by highlighting the need for standardization and more data on the effectiveness of these ablation therapies for pancreatic tumors.
