Background and study aims The endoscopic report has a key role in quality improvement for gastrointestinal endoscopy. High quality standards have been set by the endoscopic societies in this field. Unlike other digestive endoscopy procedures, the quality of reporting in endoscopic ultrasound (EUS) has not been thoroughly evaluated and a reference standard is lacking. null null null null Methods We performed an international online survey concerning the attitudes of endosonographers towards EUS r...

ABSTRACT Background & Aims Indwelling plastic endoprosthesis in patients with disconnected pancreatic duct syndrome (DPDS) reduces the risk of pancreatic fluid collection (PFC) recurrence. Although lumen-apposing metal stents (LAMS) are used with increasing frequency for PFC drainage, they require timely removal and little is known about their effects in patients with DPDS and recurrence of PFC. Methods We performed a prospective study of patients who underwent endoscopic ultrasound-guided drain...

PURPOSE OF REVIEW Given the growing concerns about infection transmission from use of contaminated reusable duodenoscopes, technological advancements have been made that vary from modifications of existing designs to development of single-use devices. RECENT FINDINGS To circumvent mechanical limitations that preclude access to critical areas of a duodenoscope to perform thorough cleaning and disinfection, single-use disposable duodenoscopes have been developed. A thorough assessment of this tech...

Objective Single-use duodenoscopes have been recently developed to eliminate risk of infection transmission from contaminated reusable duodenoscopes. We compared performances of single-use and reusable duodenoscopes in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Design Patients with native papilla requiring ERCP were randomised to single-use or reusable duodenoscope. Primary outcome was comparing number of attempts to achieve successful cannulation of desired duct....

ABSTRACT Background & Aims Given the lack of procedure standardization, findings vary from analyses of pancreatic tissues collected by endoscopic ultrasound-guided fine-needle biopsy. It is not clear which needle and technique yield best specimen for analysis. We compared the specimen quality and accuracy of diagnoses made from samples collected by fine-needle biopsy needles using different collection techniques. Methods Patients found to have pancreatic masses during imaging (n=129) were random...

While there is consensus that the COVID-19 pandemic has negatively impacted delivery of routine clinical care and has put enormous stress on the financial status of healthcare systems, definitive data on the effect of this ongoing pandemic on individual subspecialties, such as interventional endoscopy, are lacking. In an audit, we projected a 7.3% decline in the annual procedural volume, 15.2% increase in anticipated procedure-related reimbursement and 22.6% loss in downstream revenue to the hea...

Objective While single-use and detachable-tip duodenoscopes have been recently developed to overcome risks of infection transmission, there are no reliable tools to objectively assess their technical performance. We evaluated the reliability and validity of a newly developed tool to assess the technical performance of reusable duodenoscopes. Methods An assessment tool was developed to measure duodenoscope performance based on three distinct criteria: maneuverability, mechanical/imaging character...

Although rare in occurrence, adverse events such as delayed bleeding and buried stent syndrome have been reported after lumen-apposing metal stents (LAMS) placement in patients undergoing endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs). In a prospective study, we observed delayed adverse events in 6.4% of 188 patients which occurred when the PFCs were 7 cm or smaller in size and the removal of LAMS was delayed beyond 4 weeks. LAMS are being increasingly preferr...
