Ultrasonic Tomography by Means of an Ultrasonic Fiberendoscope

Abstract

The diagnositc value of ultrasonic tomography of the upper abdominal organs is sometimes limited by bones and gas. Endoscopic ultrasonography (EUST) combines the advantages of the direct visualization of the upper GI tube and the ultrasonic imaging of adjacent organs. The ultrasonic probe consists of a 5 MHz array that generates a good resolution at the acustical focus, the endoscope is a conventional Olympus gastroscope type GFB3. The ultrasonic transducer is firmly attached to the distal end of the endoscope. Combined examinations are performed in 18 patients with biliary, pancreatic and hepatic disorders or postoperative changes. EUST may be of value not only for gastrointestinal but also for retroperitoneal, cardiac, and mediastinal diseases.

Endoscopic Ultrasonography and Contrast-Enhanced Endoscopic Ultrasonography

“…In the same year, Strohm et al [2 ]reported their experience with ultrasonic fiberendoscopy of the abdomen in 18 patients with known biliary, pancreatic, and hepatic disorders or postoperative anatomic changes. The pancreas could be studied in 50% of the patients, and the lesions in patients with known pancreatic malignancies were visualized.…”

Endoscopic ultrasound in the diagnosis of foreign bodies of the colon and rectum

“…Ten years ago, 60% of gastroenterologists were already using endoscopic ultrasound in the United States. [3][4][5][6][7][8][9][10] However, in other parts of the world such as Brazil, this method is still not widespread, especially within the public health system and in rural regions.…”

EUS-Guided Antitumor Therapy for Pancreatic Tumors

“…Endoscopic ultrasonography (EUS) was introduced to clinical medicine for more than 30 years ago [1][2][3] and has contributed to the diagnosis and management of pancreatic tumors. EUS scanning system can be divided into two categories: radial and linear, with both mechanical and electronic formats available in each.…”
