 Gastrointestinal submucosal tumors(SMT), including both benign and malignant lesions, are often incidentally detected during gastrointestinal endoscopy. SMTs are often difficult to diagnose using conventional endoscopic images and forceps biopsies. It is important to observe the tumor location and echo findings in the EUS layer structure. EUS-FNA is a safe and accurate histological examination for SMTs, which has undergone technical and equipment advances, allowing the tumor to be reliably punctured. EUS-FNA examination is requested when the SMT is solid and/or is suspected to the origin of the fourth layer, even for tumors of <20mm.
