Meta-analysis: Impact of intragastric balloon therapy on NAFLD-related parameters in patients with obesity.

Background: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease affecting approximately 25% of adults in the western world. Intragastric balloon (IGB) is an endoscopic bariatric therapy -a therapeutic endoscopic tool that has shown promise in inducing weight loss. Its role in the treatment of NAFLD is yet to be established.

Higher Ustekinumab Levels in Maintenance Therapy are Associated with Greater Mucosal Healing and Mucosal Response in Crohn's Disease: An Experience of 2 IBD Centers.

Background: Ustekinumab (UST), a human monoclonal antibody that binds the p40 subunit of interleukin 12 (IL-12) and IL-23, is licensed for induction and maintenance therapy of moderate to severe inflammatory bowel disease (IBD). To date, there is limited data published on any potential association between ustekinumab serum trough levels and mucosal healing in order to guide treatment strategies and appropriate dosing.

Aim: This study aims to identify a relationship between maintenance ustekinumab serum trough levels and mucosal healing and/or response in patients with Crohn's disease in an observational cohort study.

EUS-guided choledochoduodenostomy with electrocautery-enhanced lumen-apposing metal stents in patients with malignant distal biliary obstruction: multicenter collaboration from the United Kingdom and Ireland.

Background And Aims: EUS-guided choledochoduodenostomy (EUS-CDD) with an electrocautery-enhanced lumen-apposing metal stent (EC-LAMS) has emerged as a viable method of establishing biliary drainage in patients with malignant distal biliary obstruction (MDBO). Our aim was to assess the efficacy, safety, and outcomes in patients with MDBO who underwent EUS-CDD with an EC-LAMS.

Methods: A retrospective review of consecutive patients with MDBO who underwent EUS-CDD with EC-LAMSs at 8 tertiary institutions across the United Kingdom and Ireland between September 2016 and November 2020 was undertaken.

Gender equality in academic gastroenterology: a review of gastroenterology literature over four decades.

Background: Historically males have dominated the physician ranks, although in recent years, there has been an increase in the proportion of female doctors to redress this imbalance. With such attention being paid to gender equality in society, this study aimed to characterise the changing prevalence of female authorship of peer-reviewed published research with in the field of gastroenterology.

Aims: In order to quantitatively assess the growth of female gastroenterologists, we decided to examine the changing face of gender equality within the field of academic gastroenterology from 1971 to 2010.

The optimal management of anti-drug antibodies to infliximab and identification of anti-drug antibody values for clinical outcomes in patients with inflammatory bowel disease.

Purpose: Secondary loss of response (LOR) to infliximab (IFX) commonly occurs. One cause is the development of anti-drug antibodies (ADAs). Evidence regarding the optimal management of ADAs is lacking.

Irish data on the safety and efficacy of vedolizumab in the treatment of inflammatory bowel disease.

This study reviews the safety and efficacy of treatment with vedolizumab for patients with inflammatory bowel disease across 9 Irish hospitals. It generates valuable and timely real-world data on treatment outcomes to add to the existing evidence base. Our population represents a refractory cohort with most patients previously exposed to at least one anti-TNFa agent and expressing an inflammatory phenotype.

Measuring the value of endoscopic retrograde cholangiopancreatography activity: an opportunity to stratify endoscopists on the basis of their value.

Introduction: As finite healthcare resources come under pressure, the value of physician activity is assuming increasing importance. The value in healthcare can be defined as patient health outcomes achieved per monetary unit spent. Even though some attempts have been made to quantify the value of clinician activity, there is little in the medical literature describing the importance of endoscopists' activity.

A randomized trial comparing winged versus conventional plastic stents for malignant bile duct strictures.

Background And Study Aims: Stent insertion at endoscopic retrograde cholangiopancreatography (ERCP) is an established therapy for managing malignant biliary obstruction. Conventional plastic stents with a tubular design are most commonly used despite limited patency. Plastic stents with a winged design may theoretically increase the duration of stent patency.

Therapeutic Endoscopic Ultrasound.

Endoscopic ultrasound (EUS) technology has evolved dramatically over the past 20 years, from being a supplementary diagnostic aid available only in large medical centers to being a core diagnostic and therapeutic tool that is widely available. Although formal recommendations and practice guidelines have not been developed, there are considerable data supporting the use of EUS for its technical accuracy in diagnosing pancreaticobiliary and gastrointestinal pathology. Endosonography is now routine practice not only for pathologic diagnosis and tumor staging but also for drainage of cystic lesions and celiac plexus neurolysis.

Gastrointestinal Endoscopic Ultrasound-Guided Fine-Needle Aspiration Biopsy Specimens: Adequate Diagnostic Yield and Accuracy Can Be Achieved without On-Site Evaluation.

Background: Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is the preferred method for biopsying the gastrointestinal tract, and rapid on-site cytological evaluation is considered standard practice. Our institution does not perform on-site evaluation; this study analyzes our overall diagnostic yield, accuracy, and incidence of nondiagnostic cases to determine the validity of this strategy.

Design: Data encompassing clinical information, procedural records, and cytological assessment were analyzed for gastrointestinal EUS-FNA procedures (n = 85) performed at Vancouver General Hospital from January 2012 to January 2013.

Propofol use in endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.

Compared to standard endoscopy, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are often lengthier and more complex, thus requiring higher doses of sedatives for patient comfort and compliance. The aim of this review is to provide the reader with information regarding the use, safety profile, and merits of propofol for sedation in advanced endoscopic procedures like ERCP and EUS, based on the current literature.

Impact of magnetic resonance enterography in the management of small bowel Crohn's disease.

Introduction: Magnetic resonance enterography (MRE) is a relatively new imaging modality that involves small bowel distension with orally administered fluid. Few studies have assessed its impact on patient management.

Aim: The aim of this study was to determine whether MRE influenced the management of patients with established small bowel Crohn's disease (CD).

Inter-endoscopist agreement in diagnosis of Barrett's oesophagus.

Objective: To assess how interpretation of abnormalities at the oesophago-gastric junction (OGJ) when making a diagnosis of Barrett's oesophagus (BO) varies between endoscopists and to examine the impact of the endoscopy experience on these decisions.

Design/setting: Members of the Irish Society of Gastroenterology who regularly perform gastroscopy were invited to participate in a web based image assessment study.

Interventions: Questions were posed to ascertain level of endoscopy experience, and participants were asked to indicate the presence or absence of BO in 12 endoscopic images of the OGJ.
