Description
Over the last decade, Endoscopic
Ultrasonography (EUS), has been the most significant
advance for imaging the gastrointestinal (GI) tract wall
and adjacent organs. EUS can provide unique
information essential to the diagnosis of both benign
and malignant disease that is often otherwise
obtainable only by surgical intervention. EUS is able
to provide detailed imaging of the five layers of the
gastrointestinal (GI) wall (seven layers with higher
frequencies) and its ability to characterise intra-mural
lesions is un-parralled.1 Due to its high accuracy in
identifying Tumour (T) and Node (N) involvement
in the locoregional staging of esophageal cancer, it is
now the recommended imaging tool for the
management of surgically resectable lesions.2
