Abstract: Gastrointestinal stromal tumor (GIST) is a common mesenchymal tumor of the gastrointestinal tract, with potential malignancy, non-specific clinical manifestations, and difficult preoperative diagnosis. In the past, surgical treatment was mainly relied on. In recent years, the development of endoscopic examination and endoscopic ultrasound technology has improved the diagnostic and pathological tissue acquisition capabilities of GIST. Endoscopic treatment has obvious advantages. This article aims to review the endoscopic diagnosis and treatment methods of GIST.
