Mohammad Yaghoobi, Yaser Meeralam, Khalil Al-Shammari
BACKGROUND AND AIMS: There is a wide range of reported sensitivity and specificity for endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of the choledocholithiasis with lack of a proper meta-analysis of diagnostic test accuracy (DTA) using head-to-head comparison. Here, we aimed at comparing the diagnostic accuracy of EUS and MRCP in detecting choledocholithiasis using appropriate methodology recommended by the Cochrane Collaboration. METHODS: A comprehensive electronic literature search up to January 2017 was done by 2 reviewers for prospective cohort studies comparing EUS and MRCP to reference standard in detecting choledocholithiasis...

BACKGROUND: Endoscopic ultrasound with fine-needle aspiration (EUS-FNA) is the most efficacious way to collect specimens from a solid lesion adjacent to the gastrointestinal tract and is performed with an internal stylet during puncture. However, its reinsertion into the needle is time-consuming. Controversy surrounds whether quality of cytology specimen improves with stylet use. We performed a meta-analysis comparing the use of stylet versus no stylet with EUS-FNA of gastrointestinal-related masses...

BACKGROUND: Ultrasound is accurate in the detection of Crohn's disease. Our aim was to identify ultrasound parameters contributing to inflammatory disease activity, develop a simple score, and validate this score prospectively. METHODS: This study comprised 2 single-center investigations. The first was a retrospective study on a population that had received colonoscopies (as a gold-standard diagnostic) within 60 days of ultrasound. The second was a prospective study on 2 populations: patients requiring induction with adalimumab and patients on adalimumab maintenance therapy...

BACKGROUND: Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606-622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al...

Endoscopic ultrasound (EUS) and endoscopic resection play an important role in gastric submucosal tumor. However, there were few articles regarding EUS and endoscopic resection of gastric schwannomas. Our aim was to evaluate the role of EUS and endoscopic resection in treating gastric schwannomas.We retrospectively reviewed 14 patients between March 2012 and April 2016 with gastric schwannomas and who received EUS and endoscopic resection. EUS characteristics, endoscopic resection, tumor features, and follow-up were evaluated in all the patients...

Background and study aims Treatment strategies for clinical (c)T2N0M0 esophageal adenocarcinoma (EAC) are subject to debate owing to the relative inaccuracy of tumor staging by endoscopic ultrasound (EUS), with profound implications in overstaged patients. We aimed to evaluate the final histological diagnosis of patients initially staged as having a cT2 tumor by EUS, and to assess the value of endoscopic reassessment by an interventional endoscopist, followed by an endoscopic resection when deemed feasible...

BACKGROUND AND AIMS: Based on the Next Accreditation System, trainee assessment should occur on a continuous basis with individualized feedback. We aimed to validate endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) learning curves among advanced endoscopy trainees (AETs) using a large national sample of training programs and to develop a centralized database that allows assessment of performance in relation to peers. METHODS: ASGE recognized training programs were invited to participate and AETs were graded on ERCP and EUS exams using a validated competency assessment tool that assesses technical and cognitive competence in a continuous fashion...

INTRODUCTION: In patients with lung cancer, left adrenal glands (LAG) suspected for distant metastases (M1b) based on imaging require further evaluation for a definitive diagnosis. Tissue acquisition is regularly performed using conventional EUS-FNA. The aim of this study was to investigate the success rate of endoscopic ultrasound guided fine-needle aspiration using the EBUS scope (EUS-B-FNA) for LAG analysis. METHODS: This is a prospective multicenter study in consecutive patients with (suspected) lung cancer and suspected mediastinal and LAG metastases...

INTRODUCTION: Endosonography guided celiac plexus neurolysis is efficacious in the management of severe pain due to advanced pancreatic cancer. Although endoscopic ultrasound (EUS) guided celiac neurolysis (CN) is mostly a safer procedure than the percutaneous posterior approach, severe complications such as paraplegia have been reported. CASE REPORT: We describe a patient with advanced adenocarcinoma of the pancreas and severe pain who developed irreversible paraplegia after EUS guided CN...

Gastric duplication is an uncommon condition in adults representing only 4-8% of all gastrointestinal duplications. It develops as a cystic growth within the thick gastric wall that is surrounded by a layer of smooth muscle and lined with gastric mucosa. It is usually asymptomatic but may present with nonspecific abdominal symptoms as well as cyst-related complications such as gastrointestinal (GI) bleeding, ulceration and even pancreatitis. They are difficult to distinguish from other gastric submucosal lesions and may also mimic a gastrointestinal tumor (GIST) or mucinous cyst of the pancreas...

BACKGROUND & AIMS: Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the GI tract. Fine needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. METHODS: This is a multicenter, prospective randomized clinical trial from six large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion...

BACKGROUND AND STUDY AIMS: Intra-abdominal and mediastinal lymphadenopathy are often difficult to diagnose, particularly in the absence of a primary lesion. Endosonography (EUS)-guided fine-needle aspiration and cytology (FNAC) has provided an easy and safe access to these lymph nodes, sparing the use of invasive and costly interventions. The main aim of this study is to assess the specificity, sensitivity, and predictive value of EUS-guided FNAC in the diagnosis of benign and malignant lymph nodes...

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 drainage not traversing the tumor. Herein, we report a case of recurrent cholangitis due to hemobilia and cholecystitis due to tumor involvement to the cystic duct after transpapillary stent placement, which was successfully managed by conversion to EUS-BD and EUS-guided gallbladder drainage in one session...

BACKGROUND AND OBJECTIVE: Needle-based confocal laser endomicroscopy (nCLE) under endoscopic ultrasound guidance is a newly developed imaging technique for pancreatic lesions and lymph nodes, enabling a subcellular level of resolution. The confocal miniprobe is an invasive instrument designed to be reused up to 10 times. Therefore, a method that ensures the complete elimination of microbial contaminants on the device is necessary. We studied the bactericidal efficacy of the Stella™ system, which purports to achieve this objective...

BACKGROUND AND OBJECTIVES: The safety and utility of endoscopic ultrasound (EUS) for the evaluation and management of gastrointestinal (GI) tract disorders among adults has been established. The literature on safety and efficacy in a pediatric referral population (under 21 years of age) is limited. We hypothesized that EUS is safe and useful in the pediatric population. We reviewed the pediatric EUS experience at a single tertiary-care system. We describe the indications, findings, safety, technical success rate, and impact on clinical outcomes...

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 to evaluate the efficacy and safety of EUS-AD with transhepatic access in case of technical success...
