Abstract:Insulinoma is a rare functional pancreatic neuroendocrine tumor characterized by excessive insulin secretion, which causes hypoglycemia. Advances in endoscopic technology have provided essential tools for the diagnosis and treatment of insulinoma. Early diagnosis and timely intervention, especially endoscopic intervention, can significantly improve survival and life quality of patients. Although insulinoma is mentioned in relevant domestic and international guidelines and consensus, there is still a lack of specific and normative implementation standards for the endoscopic diagnosis and treatment of insulinoma for reference. Therefore, Digestive Endoscopy Branch of Chinese Medical Association took the lead in organizing and inviting some experts in related fields in China to formulate Expert consensus on endoscopic diagnosis and treatment for insulinoma (2025). Based on the latest evidence-based medical evidence at home and abroad, and in accordance with the grading of recommendations assessment, development and evaluation (GRADE) system, the quality of the evidence related to endoscopic diagnosis and treatment was assessed and the strength of recommendations was classified. This consensus focuses on endoscopy-guided diagnostic and therapeutic approaches in order to provide specific references and practical guidance for standardized endoscopic diagnosis and treatment of insulinoma, and improve the quality of endoscopic diagnosis and treatment for insulinoma in China.
