Gastrointestinal endoscopic ultrasonography

Medical Clinics of North America, 2002
Although conventional endoscopy provides excellent visualization of gastrointestinal mucosa, it provides little information about intramural or nearby extramural lesions. The imaging of intraabdominal structures by conventional transabdominal ultrasound is degraded by ultrasound energy attenuation with distance.

Interventional endoscopic ultrasonography

Journal of Gastroenterology and Hepatology, 2009
AbstractEndoscopic ultrasonography (EUS) is the combination of endoscopy and intraluminal ultrasonography. This allows use of a high frequency transducer, which, due to the short distance to the target lesion, enables ultrasonographic images of high resolution to be obtained.

Endoscopic Ultrasonography of the Esophagus

World Journal of Surgery, 2000
AbstractEndoscopic ultrasonography (EUS) is a generally accepted technique for the preoperative staging of malignant tumors in the upper and lower gastrointestinal tracts. In particular, EUS has been considered the method of choice in diagnosing esophageal carcinoma due to the relative ease in performing the examination and the accuracy of staging ...

Endoscopic ultrasonography in achalasia

Gastroenterology, 1989
Six patients with known achalasia were examined by endoscopic ultrasonography before dilatation therapy. At the level of the lower esophageal sphincter, a typical enlargement of the echolayer corresponding to the muscularis propria was observed in 5 cases.

Endoscopic Ultrasonography of the Pancreas

Gastrointestinal Endoscopy Clinics of North America, 1995
The pancreas is the most technically demanding area to image with EUS. This technique, however, has found a clinical niche in evaluating patients with pancreatic cancer to determine resectability and likely will play a prominent role in the future in diagnosis through ultrasonographically directed FNA.

Endoscopic ultrasonography in pancreatitis

Annals of the College of Surgeons of Hong Kong, 2000
Endoscopic ultrasonography (EUS) is a useful imaging modality in the investigation of pancreatitis which provides a high‐resolution image of the pancreas and adjacent structures. In patients with ‘idiopathic’ pancreatitis diagnosed by conventional radiologic methods, EUS may help to identify the aetiology by detecting occult pancreatic neoplasm ...

Quality Indicators for Endoscopic Ultrasonography

The American Journal of Gastroenterology, 2006
Endoscopic ultrasonography (EUS) has become integral to the diagnosis and staging of gastrointestinal (GI) and mediastinal mass lesions. EUS-guided fine-needle aspiration (FNA) allows the endoscopist to obtain tissue or fluid for cytologic and chemical analysis, adding to the procedure’s utility.

Present and future of endoscopic ultrasonography

Digestive and Liver Disease, 2005
Endoscopic ultrasonography and endoscopic ultrasonography-guided fine needle aspiration are well-established techniques, encompassing a variety of diagnostic and therapeutic applications. Along with traditional indications that constitute everyday clinical practice in all endoscopic ultrasonography centres, new indications are emerging that resemble ...

ENDOSCOPIC ULTRASONOGRAPHY OF THE PANCREAS IN THE DOG

Veterinary Radiology & Ultrasound, 1998
Endoscopic ultrasonography was done in 12 normal adult dogs to investigate its efficacy in visualization of the pancreas. The endoscopic ultrasonographic device used in the present study had a curved‐array ultrasound transducer mounted in front of the objective lens.

Endoscopic ultrasonography: a preliminary report

Gastrointestinal Endoscopy, 1985
In order to define normal endoscopic ultrasonographic anatomy with particular emphasis on the pancreas, we studied 25 patients using a prototype ultrasound fiberoptic endoscope (model GF-UM1) and endoscopic ultrasound observation unit (model EU-M1) developed by the Olympus Corporation.
