Endosonography was carried out in a patient with an extensive juxtapapillary tumour. Radiology and endoscopy were unable to distinguish a villous adenoma from an invasive carcinoma. Endosonography revealed a mucosal hypoechoic tumour without penetration into the submucosa and muscularis propria. The common bile duct, pancreatic duct, and pancreas were normal. Lymph node abnormalities were not f...

UNLABELLED Anal fistula is a benign inflammatory disease with unclear etiology which develops in approximately 10 in 100 000 adult patients. Surgical treatment of fistulae is associated with a risk of damaging anal sphincters. This usually happens in treating high fistulae, branched fistulae, and anterior ones in females. In preoperative diagnosis of anal fistulae, endosonography and magnetic r...

CONTEXT The identification of a bulging covered by normal epithelium is a common finding during an upper gastrointestinal endoscopy. OBJECTIVE To compare the endoscopic and endosonography findings in the differential diagnosis of the gastrointestinal bulging (subepithelial tumor or extrinsic compression). METHOD Patients referred by endosonography with bulging of upper gastrointestinal trac...

BACKGROUND Endosonography has been successfully used in staging gastrointestinal cancer, but its value is as yet undetermined in laryngology. METHODS This prospective study includes 84 patients undergoing microlaryngoscopy for laryngeal cancer. The results of endosonography were compared with those of CT and MRI in the 76 surgical cases. RESULTS In the assessment of laryngal cancer, endoson...

BACKGROUND/AIMS Endosonography is an effective diagnostic tool for evaluating pancreatobiliary diseases. However, it is scarcely used in our healthcare system because of limited resources and scarcity of trained personnel. The aim of this study was to evaluate the role of endosonography in patients presenting with extrahepatic biliary obstruction in the Indian subcontinent. METHODS Fifty cons...

CONTEXT Mediastinal nodal staging is recommended for patients with resectable non-small cell lung cancer (NSCLC). Surgical staging has limitations, which results in the performance of unnecessary thoracotomies. Current guidelines acknowledge minimally invasive endosonography followed by surgical staging (if no nodal metastases are found by endosonography) as an alternative to immediate surgical...

BACKGROUND Theoretical testing provides the necessary foundation to perform technical skills. Additionally, testing improves the retention of knowledge. OBJECTIVES The aims of this study were to develop a multiple-choice test in endosonography for pulmonary diseases and to gather validity evidence for this test. METHODS Initially, 78 questions were constructed after informal conversational ...

Patients may be referred for endosonography after endoscopic resection of polyps because of cancer identified in the histologic specimen. To assess the effects of electrocautery-induced tissue changes on tumor staging by endosonography, endosonography findings after endoscopic removal of large polyps were correlated with surgical and endoscopic pathology. Endosonography findings revealed irregu...

OBJECTIVES In patients with lung cancer, endosonography has emerged as a minimally invasive method to obtain cytological proof of mediastinal lymph nodes, suspicious for metastases on imaging. In case of a negative result, it is currently recommended that a cervical mediastinoscopy be performed additionally. However, in daily practice, a second procedure is often regarded superfluous. The goal ...

An obstructed biliary system is usually drained by endoscopic retrograde cholangiopancreatography, and when this is unsuccessful, the standard alternative technique is percutaneous transhepatic biliary drainage. Surgical biliary bypass may also be required. In recent years, endosonography has transformed from a solely diagnostic procedure to one with therapeutic capabilities. Endosonography-gui...
