BACKGROUND The negative predictive value of endoscopic ultrasonography-guided fine needle aspiration for the diagnosis of solid pancreatic lesions remains low, and the biopsy specimens are sometimes inadequate for appropriate pathological diagnosis. AIMS To evaluate the usefulness of a novel method of contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for the ...

The aim of this study was to prospectively evaluate endoscopic ultrasonography and microscopic examination of duodenal bile in the diagnosis of cholecystolithiasis not detected by conventional ultrasonography. Forty five consecutive patients (26 females, 19 males, mean age: 50 years) with suspected cholecystolithiasis and at least two normal transcutaneous ultrasonography examinations were incl...

It is estimated that 3.4% of patients qualified for cholecystectomy due to cholelithiasis have a coexisting choledocholithiasis. For decades, endoscopic ascending retrograde cholangiopancreatography has been the golden diagnostic standard in cases of suspected choledocholithiasis. The method is associated with a relatively high rate of complications, including acute pancreatitis, the incidence ...

Innovations in stent technology and technological advances in endoscopic ultrasonography have led to rapid expansion of their use in the field of gastrointestinal diseases. In particular, endoscopic ultrasonography-guided metal stent insertion has been used for the management of pancreatic fluid collection, bile duct drainage, gallbladder decompression, and gastric bypass. Endoscopic ultrasonog...

Objective: To investigate diagnostic value and clinical significance of ultrasonic contrast and endoscopic ultrasonography in preoperative staging of gastric carcinoma. Methods: 65 patients with gastric cancer were randomly selected from our hospital from February 2015 to February 2017 as the study objects and all of them were treated with ultrasonic contrast and endoscopic ultrasonography foll...
