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 ...

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...

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...

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...
