Background and study aims  The low sensitivity of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), especially for the diagnosis of serous cystadenomas (SCAs), can be associated with diagnostic uncertainty that can regularly lead to unnecessary surgical procedures. Needle-based confocal laser endomicroscopy (nCLE) used with EUS-FNA improves diagnostic accuracy, helping to reduce un...

Background. The utility of repeat EUS in patients with suspicion for pancreatic cancer after non-diagnostic EUS-FNA study is not well established. Aim. Determine the accuracy of repeat EUS-FNA in patients with suspected pancreatic cancer and prior non-diagnostic EUS-FNA. Methods. Retrospective cohort study. Results. From 2002 to 2008 in our institution 28 patients underwent repeat EUS-FNA for s...

BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is a common technique for assessing the pancreas and the biliary system; however, the potential complications have raised concern among endoscopists and patients. Recently, the need of endoscopic ultrasound (EUS) as an additional tool of assessment before the ERCP procedure has been increasing. The need of EUS in developing countr...

introduction and aims: prior investigators have proposed microlithiasis as a causative factor for occult gallbladder diseases. endoscopic ultrasonography (eus) is potentially far more sensitive than transabdominal ultrasonography (tus) in visualizing small stones. the aim of this study was to investigate the role of endoscopic ultrasounography (eus) in the diagnosis of microlithiasis in patient...

background : the portal system and azygos vein are the main drainage systems during portal hypertension. this study aims to compare the diameter of these veins by endoscopic ultrasonography (eus) inpatients with and without chronic liver disease (cld). materials and methods : during one year, patients with cld enrolled as the study group. patients who underwent eus for other reasons during the ...

Endoscopic retrograde cholangiography (ERCP) is widely used as a first-line therapy for biliary drainage. ERCP occasionally fails owing to anatomical or technical problems, despite high reported success rates. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has recently emerged as an effective alternative biliary drainage method after unsuccessful ERCP. EUS-BD can be essentially divided ...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, i...

obstructed hepaticojejunostomy loop treated by one-step endoscopic ultrasound-guided gastroenterostomy Endoscopic ultrasound (EUS)-guided gastroenterostomy is an experimental procedure that is emerging as a minimally invasive alternative to surgical bypass and to luminal endoscopic stent placement [1,2]. We report successful treatment of a 50-year-old woman who was referred withmalignant obstru...

Endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections and of the gallbladder and bile duct after failure of standard procedures is becoming an attractive minimally invasive alternative to percutaneous drainage [1–3]. These procedures have been facilitated by the development of a specifically designed lumen-apposing self-expandable metal stent (LA-SEMS) and electrocautery-e...

Background: Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) is a novel modality in the treatment of solid tumours. The aim study to evaluate technical feasibility, safety and efficacy multiple-round EUS-RFA with low power for unresectable pancreatic cancer.
