The role of endoscopic ultrasound (EUS) in the detection of pancreatic islet cell tumours is reviewed. Functioning islet cell tumours are frequently small at presentation (90%< 2 cm). Advances in cross-sectional imaging with CT and MRI have resulted in improved detection rates of these small lesions. The sensitivity of EUS in the detection of insulinoma is similar to helical or multislice CT, i...

Endoscopic ultrasound-guided biliary drainage (EUS-BD) has been increasingly reported as an alternative to percutaneous transhepatic biliary drainage in failed endoscopic retrograde cholangiopancreatography. Moreover, conversion to EUS-BD can be a good alternative when transpapillary biliary drainage is technically possible but complicated by cholangitis because EUS-BD enables one-step internal...

Advances in echoendoscopes and their processors have significantly expanded the role of EUS and its clinical applications.The diagnostic and therapeutic capabilities of EUS continue to evolve and improve. EUS has made a large impact on patient care but comes with significant startup and maintenance costs. As improved technology continues to enhance image resolution while decreasing the size of ...

Background and study aims  Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esopha...

BACKGROUND Previous assessments of endoscopic ultrasound (EUS) classification of esophageal cancer are dominated by symptomatic patients with advanced stage disease. Fewer data exist on EUS errors in a cohort balanced between early and advanced disease. PURPOSE Assess EUS errors in classification of esophageal cancer in a more balanced cohort, and identify clinical and tumor characteristics a...

AIM To evaluate the accuracy of endoscopic ultrasound (EUS) in early esophageal cancer (EC) performed in a high-volume tertiary cancer center. METHODS A retrospective review of patients undergoing esophagectomy was performed and patients with cT1N0 and cT2N0 esophageal cancer by EUS were evaluated. Patient demographics, tumor characteristics, and treatment were reviewed. EUS staging was compa...

BACKGROUND AND AIMS There is no evidence of postoperative metastasis of gastric gastrointestinal stromal tumors (GISTs) smaller than 2 cm. The aim of this study was to evaluate the clinical usefulness of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) for gastric subepithelial lesions (SELs) smaller than 2 cm. PATIENTS AND METHODS Using a prospectively maintained EUS-FNA databas...

BACKGROUND AND OBJECTIVES Endoscopic ultrasound (EUS)-guided biliary drainage techniques are alternative procedures in cases of obstructive jaundice with altered anatomy or failed ERCP. Complications related to EUS-guided antegrade drainage (EUS-AD) are still present in up to 10% of cases, and combination of procedures is sometimes suggested to avoid adverse events. The purpose of our study is ...

Percutaneous-assisted transprosthetic endoscopic therapy (PATENT) is a novel endoscopic technique recently developed which uses a nonnatural orifice to gain access to the gastrointestinal tract for performance of interventional procedures during a single session [1]. PATENT permits endoscopic retrograde cholangiopancreatography (ERCP) in patientswith longlimb Roux-en-Y gastric bypass (RYGB) and...

21 After spinal cord injury (SCI), the neurogenic bladder is observed to develop asynchronous 22 bladder and external urethral sphincter (EUS) contractions in a condition known as detrusor 23 sphincter dyssnergia (DSD). Activation of the EUS spinal controlling center located at upper 24 lumbar spinal cord may contribute to reduce EUS dyssynergic contractions and decrease urethral 25 resistance ...
