#1 (25.2%)
Show abstract

Background and AimsEmergency admission with foreign body in the oesophagus (FBO) commonly requires endoscopic removal. Oesophageal food bolus obstruction is often due to eosinophilic oesophagitis (EoE). Patients with food bolus obstruction should undergo endoscopy and multilevel oesophageal biopsies to exclude EoE. This national retrospective study examined the management, including endoscopy and follow-up, of patients presenting as an emergency with FBO. MethodsThe Hospital Episode Statistics ...

Real World Experience and Clinical Utility of EsoGuard(R) - Interim Data from the Lucid Registry
2023-09-27 gastroenterology 10.1101/2023.09.26.23296162
#1 (25.1%)
Show abstract

BackgroundBarretts Esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), and guidelines exist for screening, surveillance, and treatment. However, historically most high-risk individuals have not been reliably screened, likely due to a combination of factors associated with patient/physician awareness and use of upper endoscopy (UE) as the traditional screening test. EsoGuard(R) (EG) is a DNA biomarker assay, and EsoCheck(R) (EC) is a non-invasive, swallowable capsule de...

Potassium-competitive acid channel blockers versus Proton-Pump inhibitors in the prevention of post-endoscopic peptic ulcer rebleeding: A systematic review and meta-analysis
2026-03-06 gastroenterology 10.64898/2026.03.02.26346403
#1 (24.8%)
Show abstract

Introduction Vonoprazan, a new oral potassium-competitive acid blocker (PCAB), has shown promise in terms of superior acid suppression when compared to Proton pump inhibitors (PPIs). We evaluated the efficacy of PCABs versus PPIs in preventing rebleeding in high-risk peptic ulcer patients after endoscopic hemostasis. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines, we conducted a comprehensive search for relevant studies across Medline...

#1 (23.8%)
Show abstract

BackgroundChronic nausea and vomiting syndromes (CNVS), gastroparesis and functional dyspepsia (FD) are complex disorders. Body Surface Gastric Mapping (BSGM), a new test of gastric function, using Gastric Alimetry(Alimetry, New Zealand) may be useful for de-escalating healthcare utilisation. This study aimed to define healthcare costs and estimate health economic impacts of implementing this test in patients with chronic gastroduodenal symptoms. MethodsConsecutive patients at a tertiary referr...

#1 (23.7%)
Show abstract

BackgroundGastric cancer remains a major cause of cancer mortality worldwide, including in intermediate-risk countries. While endoscopic screening has proven effective in high-risk populations, its impact and economic value in intermediate-risk settings remain uncertain. ObjectiveThis systematic review and meta-analysis aimed to evaluate the effectiveness and cost-effectiveness of endoscopic screening for gastric cancer in these countries. DesignA systematic review and meta-analysis was conduc...

#1 (23.0%)
Show abstract

Background/ObjectiveThere is a paucity of data on the management of gastrointestinal (GI) bleeding in patients with COVID-19 amid concerns about the risk of transmission during endoscopic procedures. We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19. MethodsIn this retrospective analysis, 24 of 1342 (1.8%) patients with COVID-19, presenting with GI bleeding from 22 April to 22 July 2020, were included. ResultsThe mean age of patients was 45.8{+/...

2020-04-11 gastroenterology 10.1101/2020.04.10.20057976
#1 (22.8%)
Show abstract

Background and AimsThere is a high unmet need for the treatment of gastroparesis and studies of NK1-R antagonists suggest potential benefit in reducing the symptoms of nausea and vomiting. We hypothesized that tradipitant, an NK1-R antagonist, would be effective in treating patients with idiopathic or diabetic gastroparesis. MethodsIn a randomized, double-blind, placebo-controlled study across 47 U.S. sites, 152 gastroparesis patients were randomized to receive oral 85mg BID tradipitant (n=77) ...

2026-01-27 gastroenterology 10.64898/2026.01.26.26344849
#1 (22.7%)
Show abstract

ObjectivesGastric cancer (GC) is a leading cause of cancer mortality in the United States (U.S.), yet no routine screening strategy exists. Opportunistic upper endoscopy (EGD) performed during screening colonoscopy (EGD-SC) may provide a practical early detection approach. We evaluated the feasibility, acceptability, patient perspectives, and diagnostic yield of EGD-SC. MethodsThis single-center, open-label, single-arm prospective trial enrolled adults aged 45-80 years scheduled for colonoscopy...

#1 (22.5%)
Show abstract

BackgroundUnderwater endoscopic mucosal resection (UEMR) is an emerging alternative to conventional endoscopic mucosal resection (CEMR). We intended to compare both techniques for colorectal polyp resection. MethodsA comprehensive search of several databases to identify studies published until November 2021 was performed. Inclusion criteria included studies comparing UEMR to CEMR in adult patients. The calculation was done by standard meta-analysis methodology, and heterogeneity was assessed us...

'It's a helluva journey': A qualitative study of patient and clinician experiences of nausea and vomiting syndromes and functional dyspepsia
2022-08-10 gastroenterology 10.1101/2022.08.09.22278607
#1 (20.1%)
Show abstract

BackgroundChronic gastroduodenal disorders including chronic nausea and vomiting syndrome, gastroparesis, and functional dyspepsia, are challenging to diagnose and manage. The diagnostic and treatment pathways for these disorders are complex, costly and overlap substantially; however, experiences of this pathway have not been thoroughly investigated. This study therefore aimed to explore clinician and patient perspectives on the current clinical pathway. MethodsSemi-structured interviews were c...

2022-12-09 gastroenterology 10.1101/2022.12.08.22283167
#1 (19.3%)
Show abstract

ObjectivesCurcumin has been claimed to have gastrointestinal benefits, including dyspepsia, a common disorder that could be managed in a primary care setting with behavioral and dietary modifications as well as over-the-counter medications. This study aimed to compare the efficacy of curcumin versus omeprazole in improving patient-reported outcomes. DesignPatients with functional dyspepsia were randomized to curcumin alone (C), omeprazole alone (O), or curcumin plus omeprazole (C+O). Patients i...
