Endoscopic ultrasonography in the evaluation of XXXX and extramucosal cysts of the esophagus.

@entity1 @entity154 @entity5 @entity2910 @entity28129 @entity2909
BACKGROUND/AIMS: @entity2909 is the most common type of @entity5 , whereas extramucosal cysts of the esophagus are @entity154 frequently asymptomatic in the adult and in most cases detected incidentally on chest x-ray. It is worthwhile considering these conditions together, because they present similar diagnostic and surgical problems. Conventional imaging tests do not lead to a precise diagnosis. The purpose of this study was to evaluate the use of endoscopic ultrasonography in the diagnosis of, and planning of treatment modalities for, these conditions. METHODOLOGY: Fifteen @entity1 with @entity2910 and seven @entity1 with extramucosal @entity28129 were studied with endoscopic ultrasonography using an Olympus GF- EU-M3 instrument with a 7.5-12 MHz echoprobe. In all @entity1 , the results of endoscopic ultrasonography were compared with the histology of the resected specimens. RESULTS: The histology of the resected specimens confirmed the endosonographic diagnosis in all @entity1 . No @entity5 was found in any specimen. CONCLUSIONS: Endoscopic ultrasonography is very accurate in visualizing these lesions and differentiating cystic from solid submucosal esophageal masses; in addition, the test can establish the exact location of the mass in relation to the esophageal wall and mediastinum. Therefore, endoscopic ultrasonography has a great impact in confirming the diagnosis of @entity2909 and extramucosal cysts of the esophagus and facilitates therapeutic decision-making because of its capacity to clearly define the size, layer of the origin, and pattern of the mass.
