Endoscopic treatment of gastroesophageal reflux disease (GERD) is becoming more and more popular, but there is no industry guidance for its application. In order to standardize the endoscopic treatment of GERD, Committee of Gastroesophageal Reflux Disease, Chinese Association of Gastroenterologist and Hepatologist, and Esophageal Diseases Group of Chinese Society of Digestive Endoscopology organized domestic experts in relevant fields to search and discuss relevant literatures at home and abroad, hold four expert seminars, and form this expert consensus. The expert consensus involves the diagnosis of GERD, evaluation before endoscopic treatment, guidance and effect evaluation of endoscopic treatment, as well as management and follow-up after GERD endoscopic treatment.
