Endoscopic treatment for reflux esophagitis is mainly minimally invasive endoscopic procedures, including radiofrequency ablation, fundoplication, and anti-reflux mucosal resection. Reflux esophagitis is a type of gastroesophageal reflux disease (GERD), a group of diseases in which acid reflux leads to breakage of the esophageal mucosa and clinical manifestations of acid reflux and heartburn in patients. The disease is mainly treated by medication, including drugs that inhibit gastric acid secretion, protect the mucosa, and promote gastrointestinal dynamics. Endoscopic treatment can also be considered for patients with more severe disease and ineffective drug treatment. Endoscopic treatment mainly involves minimally invasive endoscopic surgery, which is currently in the exploratory stage, and includes radiofrequency ablation, gastric fundoplication, and anti-reflux mucosal resection. Among them, radiofrequency ablation studies have shown some efficacy, and fundoplication and other procedures can also be considered, with better safety, but the long-term efficacy remains to be proven. Patients with reflux esophagitis should go to the hospital in time, and choose the treatment plan under the guidance of the doctor, so as not to delay the condition.
