The recent increase in the incidence of superficial esophageal cancer and promising developments in potentially curative endoscopic therapies have placed endoscopic ultrasound in a central position with regard to decision making. This is a review of the literature to determine the role of endoscopic ultrasound and high frequency probe ultrasonography in the assessment of superficial esophageal ...
IntroductIon Endoscopic ultrasonography (EUS) and EUSguided fine-needle aspiration (EUS-FNA) are now well-established modalities in the evaluation of mediastinal and abdominal lesions. In the thorax, EUSFNA has been repeatedly demonstrated to be effective in the diagnosis and staging of esophageal and lung cancer as well as the evaluation of lymphadenopathy.1 Several case reports have shown EUS...
Endoscopic ultrasonography (EUS) has recently emerged as an alternative means of providing data for patients with portal hypertension that is more accurate, less invasive and reproducible. It is well established that video-echo endoscopy, with combined endoscopic and sonographic examination, is comparable to endoscopy in diagnosing esophageal varices, but is more sensitive in diagnosing the pre...
Gastric lymphangioma is a rare benign gastric tumor composed of unilocular or multilocular lymphatic spaces. On gastrofiberscopy a submucosal tumor covered with smooth transparent normal mucosa is revealed in the stomach with or without a stalk. Endoscopic ultrasonography has become an indispensable tool for differentiating these gastric tumors. Treatment of lymphangioma depends on its size, lo...
Mucosa-associated lymphoid tissue lymphoma mainly arises in the stomach, with fewer than 30% arising in the small intestine. We describe here two cases of primary duodenal mucosa-associated lymphoid tissue lymphoma which were evaluated by endoscopic ultrasonography. A 52-year-old man underwent endoscopy due to abdominal pain, which demonstrated a depressed lesion on duodenal bulb. Endoscopic ul...
