 Biopsy of SEL(subepithelial lesions)became important with the establishment of the concept of gastrointestinal stromal tumors. Although bowling biopsy is available as a simple biopsy method, its low diagnostic ability is a problem. EUS-FNA(endoscopic ultrasound-guided fine-needle aspiration)has emerged as a solution, and it is now the first choice for SEL biopsy. EUS-FNA is excellent in that the tumor can be reliably punctured under the ultrasonic endoscope, and development of this special scope and puncture needle has made it possible to obtain diagnostic capability of ≧90%. Also, in recent years, an open biopsy method has been enforced. In this report, we will introduce the bowling and open biopsy methods, focusing on the fundamentals and tips for performing the EUS-FNA technique.
