Although EUS has enhanced our ability to diagnose and treat a wide variety of GI conditions, there are many controversial issues regarding the appropriate application of EUS techniques. In this review we discuss five controversial topics in EUS: the utility of EUS in staging of esophageal and gastric cancer; selection of appropriate needle gauge for fine needle aspiration (FNA); use of the stylet in FNA; and the emerging role of contrast agents in endoscopic ultrasound.en-USReviewsEndoscopic ultrasoundcontroversiesgastric canceresophageal cancercontrast enhancedfine needle aspirationJournal Article2014-04-1110.1093/gastro/got010
