Single-use duodenoscopes and duodenoscopes with disposable end caps
Arvind J. Trindade, Andrew Copland, Amit Bhatt, Juan Carlos Bucobo, ... David R. Lichtenstein
doi : 10.1016/j.gie.2020.12.033
Volume 93, Issue 5, May 2021, Pages 997-1005
Multidrug-resistant infectious outbreaks associated with duodenoscopes have been documented internationally. Single-use duodenoscopes, disposable distal ends, or distal end cap sealants could eliminate or reduce exogenous patient-to-patient infection associated with ERCP.
Computer-aided diagnosis of esophageal cancer and neoplasms in endoscopic images: a systematic review and meta-analysis of diagnostic test accuracy
Chang Seok Bang, Jae Jun Lee, Gwang Ho Baik
doi : 10.1016/j.gie.2020.11.025
Volume 93, Issue 5, May 2021, Pages 1006-1015.e13
Diagnosis of esophageal cancer or precursor lesions by endoscopic imaging depends on endoscopist expertise and is inevitably subject to interobserver variability. Studies on computer-aided diagnosis (CAD) using deep learning or machine learning are on the increase. However, studies with small sample sizes are limited by inadequate statistical strength. Here, we used a meta-analysis to evaluate the diagnostic test accuracy (DTA) of CAD algorithms of esophageal cancers or neoplasms using endoscopic images.

Molecular analysis of EUS-acquired pancreatic cyst fluid for KRAS and GNAS mutations for diagnosis of intraductal papillary mucinous neoplasia and mucinous cystic lesions: a systematic review and meta-analysis
Thomas R. McCarty, Swathi Paleti, Tarun Rustagi
doi : 10.1016/j.gie.2020.12.014
Volume 93, Issue 5, May 2021, Pages 1019-1033.e5
Although molecular analysis of pancreatic cyst fluid may aid pancreatic cyst classification, clinical practice remains highly variable. Therefore, we performed a systematic review and meta-analysis to evaluate the diagnostic performance of KRAS and GNAS mutations in EUS-acquired pancreatic cyst fluid for diagnosis of intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic lesions (MCLs).

Pocket-creation method versus conventional method of endoscopic submucosal dissection for superficial colorectal neoplasms: a meta-analysis
Qingshan Pei, Huimei Qiao, Mingyan Zhang, Guangchuan Wang, ... Yongjun Shi
doi : 10.1016/j.gie.2021.01.007
Volume 93, Issue 5, May 2021, Pages 1038-1046.e4
The pocket-creation method (PCM) is a newly developed strategy for colorectal endoscopic submucosal dissection (ESD). However, its superiority over the conventional method (CM) has not been established. The aim of this meta-analysis was to evaluate the efficacy and safety of PCM-ESD compared with CM-ESD for superficial colorectal neoplasms (SCNs).

With an increasing number of women joining procedural fields, including gastroenterology, optimizing the work environment for learning, teaching, and clinical practice is essential to the well-being of both physicians and their patients. We queried female and male gastroenterologists on their beliefs toward the endoscopy suite environment, as well as their experiences in learning and teaching endoscopic skills.

doi : 10.1016/j.gie.2020.10.001
Volume 93, Issue 5, May 2021, Pages 1060-1064.e1
Elective endoscopy resumed in our outpatient ambulatory center after instituting the preprocedure policy of a confirmed negative coronavirus disease 2019 (COVID-19) reverse transcriptase polymerase chain reaction (RT-PCR) status performed 72 hours before a scheduled procedure as mandated by the state of Illinois. In addition, all patients were required to contemporaneously complete the American Society for Gastrointestinal Endoscopy (ASGE) COVID-19 risk screening questionnaire published April 28, 2020 as outlined in the ASGE guidance document for reopening GI endoscopy during the COVID-19 pandemic. The aim of our study is to report the outcomes of 1000 patients who successfully completed the clinical aspects of the ASGE COVID-19 risk screening questionnaire and whose RT-PCR tests were valid for interpretation.

Volume 93, Issue 5, May 2021, Pages 1065-1073.e3
At present, the surveillance strategy for premalignant esophageal lesions in China is based solely on the pathologic diagnosis in Lugol’s chromoendoscopy (LCE). In this study, we sought to determine the degree to which various unstained features under LCE may lead to improved ability to predict the risk of progression in esophageal lesions.

Volume 93, Issue 5, May 2021, Pages 1077-1085.e1
A gastrostomy tube is often required for inpatients requiring long-term nutritional access. We compared the safety and outcomes of 3 techniques for performing a gastrostomy: percutaneous endoscopic gastrostomy (PEG), fluoroscopy-guided gastrostomy by an interventional radiologist (IR-gastrostomy), and open gastrostomy performed by a surgeon (surgical gastrostomy).

EUS-guided gastroenterostomy (EUS-GE) is increasingly used as an alternative to surgery and enteral stent placement to manage gastric outlet obstruction (GOO). However, no data are available on the learning curve (LC) for EUS-GE. Defining the LC is necessary to create adequate subspecialty training programs and quality assurance.

Comparing a conventional and a spring-and-loop with clip traction method of endoscopic submucosal dissection for superficial gastric neoplasms: a randomized controlled trial (with videos)

Volume 93, Issue 5, May 2021, Pages 1097-1109
Several traction methods have sought to overcome the technical difficulties of endoscopic submucosal dissection (ESD). However, traction direction has remained limited in most of these methods, with lack of clarity about the optimal method and traction direction for gastric ESD. A spring-and-loop with clip (SLC) has been developed as a multidirectional traction device. Here, we investigated whether SLC traction-assisted ESD (SLC-ESD) improved procedure-related outcomes compared with conventional ESD (C-ESD) among patients with superficial gastric neoplasms.

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.

EUS-guided FNA is recommended as a first-line procedure for the histopathologic diagnosis of pancreatic cancer. Molecular analysis of EUS-FNA samples might be used as an auxiliary tool to strengthen the diagnosis. The current study aimed to evaluate the diagnostic performances of K-ras testing using droplet digital polymerase chain reaction (ddPCR) and a novel single-nucleotide variant (SNV) assay performed on pancreatic EUS-FNA samples.

One of the difficulties in performing endoscopic submucosal dissection (ESD) is the lack of retraction during submucosal dissection. The development of the EndoMaster EASE System (EndoMaster Pte Ltd, Singapore) aims to enhance the safety and efficacy of ESD through 2 flexible robotic arms for tissue retraction and dissection. This is a preclinical animal study to evaluate the performance of colorectal ESD using the latest version of the EndoMaster EASE System.
