Video Tip: Radiofrequency Energy Delivery | November 2021-Radiofrequency Energy Delivery

Video Transcription

So let's talk about some endoscopic interventions  as we finish up the talk. The first dimension is radiofrequency energy delivery. This is the strata system, for those of you who may be familiar with it,  where ablation is performed delivery of that radiofrequency energy delivery at six levels in the area of the esophagogastric junction. It's done as an outpatient endoscopy,  and it does not preclude the use of other antireflux measures in the future. We don't really know why it works. Compliance was thought to be the reason, but it can be reversible.  There is not necessarily a bulking up of the tissue, but it does seem to work, and there's a nice meta-analysis that was put out with over 1,400 patients before,  showing improvement in symptom scores, as well as improvement in esophageal acid exposure. It does not work in patients who have any significant hiatal hernia,  and it is thought to be the weakest of the antireflux anatomic interventions that we have, but can be durable in its response, and in certain patients, for example,  those who had a sleeve gastrectomy already, those who are not stable enough to undergo a longer antireflux intervention and need a temporizing measure,  like a pre-lung transplant patient, this may be something that we can consider for those folks. Thank you.

Video Summary

In this video, the speaker discusses endoscopic interventions, specifically focusing on radiofrequency energy delivery using the Strata system. This outpatient procedure involves delivering radiofrequency energy at six levels near the esophagogastric junction. While the mechanism of action is not fully understood, it has shown promising results in improving symptoms and reducing esophageal acid exposure, according to a meta-analysis of over 1,400 patients. However, it is not effective for patients with significant hiatal hernia and is considered a relatively weak antireflux intervention. It may be suitable for certain patients, such as those who have already undergone a sleeve gastrectomy or require a temporary measure before a lung transplant. No credits were mentioned.
