Diagnosis of submucosal lesions of the upper gastrointestinal tract by endoscopic ultrasonography.

abstract：BACKGROUND:The natural history of a bleeding peptic ulcer with a tightly adherent blood clot remains uncertain. Controversy exists concerning removal of such blood clots at the bleeding ulcer base. This article presents the natural history of a bleeding peptic ulcer with a tightly adherent clot and defines the characte...
