The application progress of endoscopic ultrasound in the diagnosis of gastrointestinal stromal tumor
The gastrointestinal stromal tumor(GIST)is a potentially malignant mesenchymal tumor.Different treat-ment strategies are selected for GIST with different malignant risks,such as follow-up,endoscopic therapy,surgical re-section or/and drug therapy.Therefore,early diagnosis and risk assessment of GIST are very important for the selection of treatment.Now,with the application of endoscopic techniques,endoscopic ultrasound(EUS),endoscopic elastic im-aging(EUS-EG),contrast-enhanced harmonic endoscopic ultrasound(CH-EUS),and endoscopic ultrasound-guided fine-needle aspiration/biopsy(EUS-FNA/EUS-FNB)have been applied in the diagnosis and risk assessment of GIST.Therefore,this article provided an overview of the application of the above checking methods in GIST.
