Development and validation of artificial neural networks model for detection of Barrett’s neoplasia: a multicenter pragmatic nonrandomized trial (with video)
The aim of this study was to develop and externally validate a computer-aided detection (CAD) system for the detection and localization of Barrett’s neoplasia and assess its performance compared with that of general endoscopists in a statistically powered multicenter study by using real-time video sequences.Expanding the role of pneumatic dilation for nonachalasia patients: a comparative study
Treatment options for nonachalasia obstructive disorders of the esophagogastric junction (EGJ) are limited. The aim of this study was to assess the treatment efficacy of pneumatic dilation (PD) for the disorders of EGJ outflow obstruction (EGJOO) and postfundoplication EGJ obstruction (PF-EGJO) and to assess attitudes regarding training in PD.Novel classification for adverse events in GI endoscopy: the AGREE classification
Standardized registration and evaluation of adverse events (AEs) are essential to assess the safety of endoscopic procedures. We propose a novel classification system, named adverse events in GI endoscopy (AGREE), adapted from a widely accepted surgical tool.Cost-effectiveness analysis of optimal diagnostic strategy for patients with symptomatic cholelithiasis with intermediate probability for choledocholithiasis
EUS, MRCP, and intraoperative cholangiogram (IOC) are the recommended diagnostic modalities for patients with intermediate probability for choledocholithiasis (IPC). The relative cost-effectiveness of these modalities in patients with cholelithiasis and IPC is understudied.Single-use duodenoscope for ERCP performed by endoscopists with a range of experience in procedures of variable complexity
Expert endoscopists previously reported ERCP outcomes for the first commercialized single-use duodenoscope. We aimed to document usability of this device by endoscopists with different levels of ERCP experience.Utility of palliative EUS-guided biliary drainage using lumen-apposing metal stents: a prospective multicenter feasibility study (with video)
Biliary drainage with ERCP is successful in only 80% to 90% of cases of extrahepatic cholangiocarcinoma and pancreatic cancer. We present the results of a multicenter prospective study assessing the safety, feasibility, and quality of life of patients after EUS-guided biliary drainage (EUS-BD) with lumen-apposing metal stents after failed ERCP.Comparing diagnostic accuracy of current practice guidelines in predicting choledocholithiasis: outcomes from a large healthcare system comprising both academic and community settings
The American Society for Gastrointestinal Endoscopy (ASGE) 2010 guidelines for suspected choledocholithiasis were recently updated by proposing more specific criteria for selection of high-risk patients to undergo direct ERCP while advocating the use of additional imaging studies for intermediate- and low-risk individuals. We aim to compare the performance and diagnostic accuracy of 2019 versus 2010 ASGE criteria for suspected choledocholithiasis.Improvement in insulin resistance and estimated hepatic steatosis and fibrosis after endoscopic sleeve gastroplasty
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the United States and is closely associated with obesity and insulin resistance (IR). Weight loss is the best treatment for NAFLD. Endoscopic sleeve gastroplasty (ESG) is a promising endoscopic procedure for treatment of obesity. Our aim is to evaluate the change in IR and estimated hepatic steatosis and fibrosis after ESG.The status of training in new technologies in advanced endoscopy: from defining competence to credentialing and privileging
The landscape of advanced endoscopy continues to evolve as new technologies and techniques become available. Although postgraduate advanced endoscopy fellowships have traditionally centered on ERCP and diagnostic EUS, the breadth of training has increased over the years in response to the ever-growing demand for therapeutic endoscopy. The increasing diversity and complexity of emerging endoscopic techniques accompanied by the shift in focus toward competency-based medical education requires innovative changes to the curriculum that will ensure adequate training yet without compromising best patient practices.Coronavirus (COVID-19) outbreak: what the department of endoscopy should know
Italy recorded its first case of confirmed acute respiratory illness because of coronavirus on February 18, 2020, soon after the initial reports in China. Since that time, Italy and nations throughout the world have adopted very stringent and severe measures to protect populations from spread of infection. Despite these measures, the number of infected people is growing exponentially, with a significant number of patients developing acute respiratory insufficiency. Endoscopy departments face significant risk for diffusion of respiratory diseases that can be spread via an airborne route, including aspiration of oral and fecal material via endoscopes.Endoscopic submucosal dissection with suturing for the treatment of weight regain after gastric bypass: outcomes and comparison with traditional transoral outlet reduction (with video)
Although traditional transoral outlet reduction (TORe) involves argon plasma coagulation (APC) before endoscopic suturing, modified endoscopic submucosal dissection (ESD) has also been used. This study aims to evaluate the safety and efficacy of modified ESD-TORe in comparison with traditional APC-TORe.Ergonomic endoscopy: An oxymoron or realistic goal?
The current endoscope design is not ergonomic. There is a high prevalence of endoscopy-related injury reported in the literature, and studies have demonstrated high-risk biomechanical exposures during the performance of routine colonoscopy. Endoscopy ergonomics focuses on understanding the endoscopist’s interaction with the endoscope and the endoscopy unit and re-designing these tasks to minimize the risk of endoscopy-related injury. The discussion to date has focused on what the endoscopist can do to minimize his or her risk of injury.Endoscopic sleeve gastroplasty in the management of overweight and obesity: an international multicenter study
Obesity is a pandemic affecting approximately 700 million adults worldwide, with an additional 2 billion overweight. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive endoscopic bariatric therapy that involves remodeling of the greater curvature in an effort to reduce gastric capacity and delay gastric emptying. A variety of ESG suture patterns has been reported. This study is the first to use a uniform “U” stitch pattern across all centers to simplify technical aspects of the procedure and limit cost.Setting minimum standards for training in EUS and ERCP: results from a prospective multicenter study evaluating learning curves and competence among advanced endoscopy trainees
Minimum EUS and ERCP volumes that should be offered per trainee in “high quality” advanced endoscopy training programs (AETPs) are not established. We aimed to define the number of procedures required by an “average” advanced endoscopy trainee (AET) to achieve competence in technical and cognitive EUS and ERCP tasks to help structure AETPs.Preoperative predictors of choledocholithiasis in patients presenting with acute calculous cholecystitis
Markedly increased liver chemistries in patients presenting with acute calculous cholecystitis (AC) often prompt an evaluation for concomitant choledocholithiasis (CDL). However, current guidelines directing the workup for CDL fail to address this unique population. The aims of this study are to define the range of presenting laboratory values and imaging findings in AC, develop a model to predict the presence of concurrent CDL, and develop a management algorithm that can be easily applied on presentation.An international, multicenter, comparative trial of EUS-guided gastrogastrostomy-assisted ERCP versus enteroscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy
ERCP is challenging in patients with Roux-en-Y gastric bypass (RYGB) anatomy. EUS-guided gastrogastrostomy (GG) creation is a promising novel technique to access the excluded stomach to facilitate conventional ERCP. We aimed to compare procedural outcomes and adverse events (AEs) between EUS-guided GG-assisted ERCP (EUS-GG-ERCP) and enteroscopy-assisted ERCP (e-ERCP) in patients with RYGB.
