Abstract:In 2018, led by Zhongshan Hospital, Fudan University, Chinese consensus on endoscopic diagnosis and management of gastrointestinal submucosal tumor (version 2018) jointly formulated by experts was developed. This consensus is the first expert consensus on the endoscopic diagnosis and management of gastrointestinal submucosal tumors (SMT) in China, which has achieved strong response at home and abroad once it was published, and has standardized the endoscopic diagnosis and management process of SMT in daily work. Digestive endoscopy has developed rapidly in recent years, and great progress has been made in endoscopic ultrasound diagnosis, endoscopic excision and suture in the past 5 years. It is urgent to develop a new expert consensus on endoscopic diagnosis and management of SMT by combining new concepts, new technologies and new experience of endoscopic diagnosis and management. Therefore, led by the Endoscopy Center of Zhongshan Hospital, Fudan University, a consensus updating working group was established to analyze the new evidence in recent years on the basis of the original consensus and form relevant recommendations, with a view to provide reference and guidance for clinicians engaged in the diagnosis and management of SMT and related staff in grass‑roots medical institutions.
