INTRODUCTION: Clinical guidelines recommend surveillance of patients with Barrett's esophagus (BE). However, the surveillance intervals in practice are shorter than policy recommendations. We aimed to determine how this policy-practice gap affects the costs and benefits of BE surveillance. METHODS: We used the Netherlands as an exemplary Western country and simulated a cohort of 60-year-old patients

OBJECTIVES: Exposure to ionizing radiation remains a hazard for patients and healthcare providers. We evaluated the utility of an artificial intelligence (AI)-enabled fluoroscopy system to minimize radiation exposure during image-guided endoscopic procedures. METHODS: We conducted a prospective study of 100 consecutive patients who underwent fluoroscopy-guided endoscopic procedures. Patients underwent

The phase II mongersen (GED-0301) trial produced unparalleled success rates in Crohn's disease and generated much hope for a crippling disease. Unfortunately, the subsequent phase III trial was terminated early because of a lack of efficacy. We discuss the differences in trial design that may have contributed to these disparate findings and how these findings may serve as a lesson in subsequent therapeutic

OBJECTIVES: The prevalence of psychiatric disease in patients with eosinophilic esophagitis (EoE) is not fully characterized. We aimed to determine the prevalence of psychiatric disease and centrally acting medication use in a cohort of children and adults with EoE and evaluated whether psychiatric disease affects the EoE clinical presentation. METHODS: We conducted a retrospective study of newly diagnosed

OBJECTIVES: Delayed postpolypectomy bleeding (DPPB) is a relatively common adverse event. Evidence is conflicting on the efficacy of prophylactic clipping to prevent DPPB, and real-world effectiveness data are lacking. We aimed to determine the effectiveness of prophylactic clipping in preventing DPPB in a large screening-related cohort. METHODS: We manually reviewed records of patients who underwent

In this edition of the journal, there is an important nested case-control study from investigators at Kaiser Permanente, Northern California. Proton pump inhibitor exposure for 10 or more years was not associated with any increased risk of gastric cancer. Small observed increased risks of colorectal, hepatocellular, and pancreatic cancers with 10 or more years of exposure are likely to have been spurious

OBJECTIVES: There are only limited data on the survival outcomes after transplanting HCV RNA–positive liver into HCV RNA–negative recipients. The objective of our study was to determine whether there were graft and patient survival differences when HCV-negative patients received HCV RNA (nucleic acid amplification testing [NAT] positive)–positive liver grafts. METHODS: We queried the United Network

OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) and sarcopenia have a close association with an increased risk of atherosclerotic cardiovascular disease (ASCVD). This study investigated the influence of NAFLD and sarcopenia on ASCVD risk. METHODS: Data from the 2008–2011 Korean National Health and Nutrition Examination Surveys database were analyzed (n = 7,191). The sarcopenia index was calculated

OBJECTIVES: We performed a study to assess the effects of a quality improvement (QI) initiative on the rates of postvariceal bleeding surveillance upper endoscopy (EGD). METHODS: We identified patients with cirrhosis hospitalized with variceal bleeding and assessed the rates of timely (≤4 weeks) EGD before and after a QI initiative.

The relevance of functional gastrointestinal (GI) disorders and their impact on quality of life for many patients has become an increasingly important topic in gastroenterology. A gastroenterologist can expect to see 40% of patients for motility and functional GI disorders, thus highlighting the necessity for physicians to have a strong foundation of knowledge in treatment strategies for these patients

OBJECTIVES Infliximab (IFX) or adalimumab (ADA) use in patients with inflammatory bowel disease (IBD) leads to increased risk of tuberculosis (TB). This meta-analysis evaluated the factors which determine this risk, with special focus on local TB incidence. METHODS All studies until January 31, 2019, which reported the development of TB in patients with IBD on IFX/ADA, were included after searching

Chronic pancreatitis (CP) is historically defined as an irreversible inflammatory condition of the pancreas leading to varying degrees of exocrine and endocrine dysfunction. Recently however, the paradigm for the diagnosis has changed in that it breaks with the traditional clinicopathologic-based definition of disease, focusing instead on diagnosing the underlying pathologic process early in the disease

Cap-assisted and chromo-colonoscopy are 2 techniques which may increase adenoma detection; however, chromo-colonoscopy is limited by increased time requirement. In this edition of The American Journal of Gastroenterology, Kim et al. present data from a randomized controlled trial comparing standard colonoscopy with an arm using both techniques (CAP/CHROMO). The indigo carmine was applied using a simpler

OBJECTIVES: Cardiac dysfunction has been implicated in the genesis of hepatorenal syndrome (HRS). It is unclear whether a low cardiac output (CO) or attenuated contractile response to hemodynamic stress can predict its occurrence. We studied cardiovascular hemodynamics in cirrhosis and assessed whether a diminished cardiac reserve with stress testing predicted the development of HRS on follow-up. METHODS:

INTRODUCTION Patients hospitalized with myocardial infarction (MI) are at risk of gastrointestinal bleeding because of the need for antiplatelet agents and/or anticoagulation. The data regarding the safety of endoscopy after MI are limited. This study sought to assess mortality rates of patients hospitalized with acute MI who require esophagogastroduodenoscopy or colonoscopy using the National Inpatient

OBJECTIVES Symptoms are inconsistently associated with esophageal motor findings on high-resolution manometry (HRM). We aimed to evaluate predictors of dysphagia severity, including esophageal hypervigilance and visceral anxiety, among patients evaluated with HRM. METHODS Adult patients undergoing HRM at 4 academic medical centers (United States and France) were prospectively evaluated. HRM was completed

OBJECTIVES Severe alcoholic hepatitis (sAH) confers substantial mortality, but the disease course is difficult to predict. As iron parameters are attractive outcome predictors in other liver diseases, we tested their prognostic ability in sAH. METHODS Serum ferritin, transferrin, iron, transferrin saturation, nontransferrin-bound iron, soluble transferrin receptor, and hepcidin were measured in 828

OBJECTIVES The risk of noncardia gastric cancer is increased in the presence of gastric intestinal metaplasia. We aimed to identify demographic and lifestyle factors independently associated with the risk of gastric intestinal metaplasia. METHODS We used data from a cross-sectional study of patients attending primary care and endoscopy clinics at the Michael E. DeBakey VA Medical Center in Houston

OBJECTIVES It was suggested that normalization of serum alanine aminotransferase (ALT) levels at 1 year of antiviral treatment is associated with a lower risk of hepatic events in patients with chronic hepatitis B (CHB). However, it remains unclear whether earlier ALT normalization is associated with lower hepatocellular carcinoma (HCC) risk, independent of fatty liver or cirrhosis and on-treatment
