INTRODUCTION Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) is an accurate method of diagnosing and staging gastrointestinal and thoracic malignancy. A key issue in maximizing FNA accuracy is to ensure that an adequate specimen is obtained. On-site cytopathology increases the diagnostic yield of EUS-FNA. However, this increases the time(More)
INTRODUCTION The endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has emerged as a minimally invasive and safe method for material procurement in the differential diagnosis of subepithelial lesions (SEL) of upper gastrointestinal tract (UGT), especially in suspicious lesions of gastrointestinal stromal tumors (GIST). There are few studies(More)
