EUS is well established for differentiation of subepithelial lesions, for T-staging of luminal gastrointestinal and pancreaticobiliary malignancies, for differentiation of benign pancreaticobiliary disorders and for diagnostic tissue acquisition, which can be achieved by EUS-guided fine needle aspiration or by EUS-guided fine needle biopsy ...

Endosonographically, various mediastinal anatomical landmarks and stations can be visualized by transesophageal scanning, thus providing arranged systematic examination of the mediastinum. In addition, the correct position during the examination is crucial for EUS-guided procedures such as tissue sampling and drainage of mediastinal abscesses.

2021年3月1日 · The stations contain anatomical landmarks which could be used to locate the transducer and to identify areas that have not been scanned. EUS of the BD can be done from the stations as follows: Station 1: the fundus of stomach (liver); Station 2: body of stomach (and antrum); Station 3: duodenal bulb; Station 4: descending duodenum [4], [5], [6].

EUS combines two basic modalities—endoscopy, which aids in luminal visualization, and high-frequency acoustic waves, which are utilized to image parts of the gastrointestinal tract, internal organs, blood vessels, and lymph nodes in its proximity [19,20].

2016年1月15日 · This chapter suggests a detailed station approach to EUS examination. The areas discussed in detail include: normal gastric and esophageal wall layers; mediastinum; pancreaticobiliary examination stations; and rectum gastric and esophageal wall.

EUS can identify lymph nodes in the posterior and inferior mediastinum. Stations 8 and 9 are accessible, as are posterior nodes at station 7 (Fig. 1).

Endoscopic ultrasonography (EUS) is considered a superior investigation when compared to conventional ultrasonography for imaging gall bladder (GB) lesions as it can provide...

2021年1月8日 · Endosonographically, various mediastinal anatomical landmarks and stations can be visualized by transesophageal scanning, thus providing arranged systematic examination of the mediastinum. In addition, the correct position during the examination is crucial for EUS-guided procedures such as tissue sampling and drainage of mediastinal abscesses.

The “ABCs of EUS: A Complete Roadmap” provides 17 narrated videos comprising of: EUS videos; literature discussion with slides of key points; diagrams and CT scans of regional anatomy along with animations to explain scope position and view orientation.

Endoscopic ultrasound (EUS) combines ultrasound and conventional endoscopy technologies to see beyond the walls of the gastrointestinal tract. EUS allows endoscopists to visualize all five layers of the GI tract, as well as surrounding tissue and organs.
