New Techniques Accuracy of Endoscopic Ultrasonography in Upper Gastrointestinal Submucosal Lesions: a Prospective Multicenter Study

Abstract

The accuracy of EUS in differentiating between submucosal tumors and extraluminal compressions is substantially superior to that of endoscopy, but EUS is still inadequate for differential diagnosis between benign and malignant submucosal tumors. However, EUS is still the best method of visualizing submucosal lesions precisely. The influence of EUS on the further management in these patients remains to be examined in subsequent studies.
