Chinese expert consensus on radiofrequency therapy for gastroesophageal reflux disease 2024

Abstract

Objective: Radiofrequency (RF) therapy is a minimally invasive procedure used to treat gastroesophageal reflux disease (GERD). During the procedure, electrodes are meticulously inserted into the lower esophageal sphincter and cardiac muscle through a gastroscope. By applying heat at various layers and sites around the gastroesophageal junction, the treatment intends to augment the junction's pressure and reduce tissue compliance. This process may also desensitize the esophagus, thereby preventing reflux and relieving symptoms. RF therapy boasts a high success rate and a low risk of adverse effects, making it an increasingly popular choice. However, there is a lack of consensus regarding its indications, contraindications, and the evaluation processes for pre- and postoperative care. To enhance the precision of patient selection and the technical execution of RF therapy, it is imperative to consolidate and standardize its clinical application in China. This will ensure the therapy's safety and efficacy are optimized. Methods: Between December 2022 and April 2024, a group of 25 Chinese endoscopists, each with experience in over 50 radiotherapy procedures, engaged in six rounds of consensus discussions. The discussions focused on several key aspects of the procedure. During these discussions, each item was put to a vote among the experts. A consensus was reached when an item received agreement from at least 80 ​% of the participants. Results: The expert group, comprising 25 specialists from 22 different institutions, had an average experience of over 50 RF procedures. These experts engaged in comprehensive discussions on a total of eight critical items, covering the full spectrum of the procedure, including indications, contraindications, basic working conditions and preparation, preoperative preparation, surgical process and technical skills, postoperative management, therapeutic effects, complications and prevention. The group successfully reached a consensus on all these items, ensuring a standardized approach to RF procedures. Conclusion: This consensus summarized and standardized the clinical application of anti-reflux RF therapy in China. Adoption of this consensus will improve the precision of patient selection and technical implementation, thereby enhancing the safety and effectiveness of anti-reflux radiofrequency therapy.
