title: Visceral vascular anomalies.
abstract: Gastrointestinal endoscopy is an essential modality often used for initial diagnostic assessment and staging of visceral vascular anomalies, especially when bleeding is the presenting symptom. Some lesions have a pathognomonic appearance on endoscopy. Others are less clearly identifiable and require a multidisciplinary assessment, including histopathology, for a correct diagnosis. Proper application of nomenclature is crucial to prevent the institution of improper therapies. Advanced endoscopic methods, including endosonography and various hemostatic techniques, are useful to evaluate the depth and character of gastrointestinal wall involvement and to provide minimally invasive treatment when appropriate.
