barrett's esophagus diagnosis

BACKGROUND & AIMS: Characterization of visible abnormalities in Barrett esophagus (BE) patients can be challenging, especially for unexperienced endoscopists. This results in suboptimal diagnostic accuracy and poor inter-observer agreement. Computer-aided diagnosis (CADx) systems may assist endoscopists. We aimed to develop, validate and benchmark a CADx system for BE neoplasia. METHODS: The CADx system received pretraining with ImageNet with consecutive domain-specific pretraining with GastroNet which includes 5 million endoscopic images...

BACKGROUND: Patients with gastroesophageal reflux (GERD) symptoms undergoing screening upper endoscopy for Barrett's esophagus (BE) frequently demonstrate columnar-lined epithelium (CLE), with forceps biopsies (FB) failing to yield intestinal metaplasia (IM). Repeat endoscopy is often necessary. AIM: Assess the yield of IM leading to a diagnosis of BE by the addition of Wide-Area Trans-epithelial Sampling (WATS-3D) to FB in the screening of GERD patients. METHODS: We performed a prospective registry study of GERD patients undergoing screening upper endoscopy...

OBJECTIVE: The causal associations of circulating lipids with Barrett's Esophagus (BE) and Esophageal Cancer (EC) has been a topic of debate. This study sought to elucidate the causality between circulating lipids and the risk of BE and EC. METHODS: We conducted two-sample Mendelian randomization (MR) analyses using single nucleotide polymorphisms (SNPs) of circulating lipids (n = 94,595 - 431,167 individuals), BE (218,792 individuals), and EC (190,190 individuals) obtained from the publicly available IEU OpenGWAS database...

Background: Barrett's esophagus and esophageal adenocarcinoma cases are increasing as gastroesophageal reflux disease increases. Using artificial intelligence (AI) and linked color imaging (LCI), our aim was to establish a method of diagnosis for short-segment Barrett's esophagus (SSBE). Methods: We retrospectively selected 624 consecutive patients in total at our hospital, treated between May 2017 and March 2020, who experienced an esophagogastroduodenoscopy with white light imaging (WLI) and LCI. Images were randomly chosen as data for learning from WLI: 542 (SSBE+/- 348/194) of 696 (SSBE+/- 444/252); and LCI: 643 (SSBE+/- 446/197) of 805 (SSBE+/- 543/262)...

SIGNIFICANCE: Endoscopic screening for esophageal cancer (EC) may enable early cancer diagnosis and treatment. While optical microendoscopic technology has shown promise in improving specificity, the limited field of view (<mml:math xmlns:mml="https://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mo><</mml:mo><mml:mn>1</mml:mn><mml:mtext>  </mml:mtext><mml:mi>mm</mml:mi></mml:mrow></mml:math>) significantly reduces the ability to survey large areas efficiently in EC screening...

BACKGROUND: The relationship among obesity, bariatric surgery, and esophageal adenocarcinoma (EAC) is complex, given that some bariatric procedures are thought to be associated with increased incidence of reflux and Barrett's esophagus. Previous bariatric surgery may complicate the use of the stomach as a conduit for esophagectomy. In this study, we presented our experience with patients who developed EAC after bariatric surgery and described the challenges encountered and the techniques used...

In patients with dysphagia that is not explained by upper endoscopy, high-resolution esophageal manometry (HRM) is the next logical step in diagnostic testing. This study investigated predictors of failure to refer for HRM after an upper endoscopy that was performed for but did not explain dysphagia. This was a retrospective cohort study of patients >18 years of age who underwent esophagogastroduodenoscopy (EGD) for dysphagia from 2015 to 2021. Patients with EGD findings that explained dysphagia (e.g. esophageal mass, eosinophilic esophagitis, Schatzki ring, etc...

Objective and Impact Statement: A clinically viable technology for comprehensive esophagus surveillance and potential treatment is lacking. Here, we report a novel multifunctional ablative gastrointestinal imaging capsule (MAGIC) technology platform to address this clinical need. The MAGIC technology could also facilitate the clinical translation and adoption of the tethered capsule endomicroscopy (TCE) technology. Introduction: Recently developed optical coherence tomography (OCT) TCE technologies have shown a promising potential for surveillance of Barrett's esophagus and esophageal cancer in awake patients without the need for sedation...

Absent contractility (AC), a motility disorder characterized by the absence of esophageal contractions while maintaining normal lower esophageal sphincter relaxation, is recognized as a distinctive major disorder of peristalsis on esophageal high-resolution manometry that warrants comprehensive understanding. This unique motility disorder often co-occurs with connective tissue, rheumatologic or autoimmune diseases, with scleroderma being the classic example. Symptoms of gastroesophageal reflux are common. AC can profoundly impact patients' lives and result in a spectrum of complications, including erosive esophagitis, esophageal candidiasis, Barrett's esophagus, and malnutrition...

Evaluating clinical care through quality-related metrics is increasingly common. There are now numerous quality statements and indicators related to the medical management of benign and pre-malignant esophageal diseases. Expert consensus leveraging evidence-based recommendations from published society guidelines has been the most frequently used basis for developing esophageal quality statements. While surgical care of patients with esophageal malignancies, including squamous cell carcinoma, has also been developed, those related to benign esophageal disease now include domains of diagnosis, treatment, and monitoring for gastroesophageal reflux disease, eosinophilic esophagitis (EoE), achalasia, and Barrett's esophagus (BE)...

BACKGROUND: Early adenocarcinoma mixed with a neuroendocrine carcinoma (NEC) component arising in the gastroesophageal junctional (GEJ) region is rare and even rarer in young patients. Here, we report such a case in a 29-year-old Chinese man. CASE SUMMARY: This patient presented to our hospital with a 3-mo history of dysphagia and regurgitation. Upper endoscopy revealed an elevated nodule in the distal esophagus 1.6 cm above the GEJ line, without Barrett's esophagus or involvement of the gastric cardia...

Cobblestone esophagus is a rare finding that has been previously described in cases of eosinophilic esophagitis (EoE), candidiasis , Barrett's esophagus, or severe reflux esophagitis from distal gastrointestinal obstruction. We describe a case of asymptomatic cobblestone esophagus secondary to bisphosphonate use.  A 67-year-old female was seen in the clinic for evaluation of microcytic anemia that was incidentally picked up on routine chronic disease follow-up. She had no gastrointestinal symptoms. She has been taking oral alendronate 70mg once a week for osteoporosis since a year ago...

INTRODUCTION: In the United States, clinical guidelines recommend daily use of proton pump inhibitors (PPIs) amongst individuals diagnosed with Barrett's esophagus to decrease the risk of progression to dysplasia and neoplasia. Prior studies documenting adherence to PPIs in this population have not characterized heterogeneity in adherence patterns. Factors that may relate to adherence are incompletely described. METHODS: We used administrative claims data from the Merative MarketScan Commercial Claims and Encounters database to conduct a retrospective study of adherence to prescription PPIs...

Although the risk of cancer progression in a Barrett's esophagus (BE) is very low, worrying about cancer is known as an important factor affecting HRQoL. The aim of this study was to determine the proportion of BE patients with high levels of worry for cancer, to compare outcomes of patients endoscopically treated for BE neoplasia (DBE), non-dysplastic BE patients (NDBE) and patients with reflux symptoms, and to examine associated factors. We performed a cross sectional, exploratory, self-administered questionnaire study using the cancer worry scale, and the reflux disease questionnaire...

Diagnosis and therapy of esophageal carcinoma is challenging and requires a multidisciplinary approach. The purpose of the updated German guideline "Diagnosis and Treatment of Squamous Cell Carcinoma and Adenocarcinoma of the Esophagus-version 3.1" is to provide practical and evidence-based advice for the management of patients with esophageal cancer. Recommendations were developed by a multidisciplinary expert panel based on an extensive and systematic evaluation of the published medical literature and the application of well-established methodologies (e...

2023 has been marked by numerous advancements in the fields of hepatology, liver transplantation, gastroenterology, and interventional endoscopy. These developments hold the promise of changing our daily practice while enhancing the diagnosis and treatment of various hepatic and gastroenterological conditions. Additionally, the European Association for the Study of the Liver (EASL) has issued recommendations for the management of hepatitis delta, acute-on-chronic liver failure, liver diseases of pregnancy, and intrahepatic cholangiocarcinoma...

OBJECTIVES: Although Barrett's esophagus (BE), especially ultra-short-segment BE (USSBE), is very frequently diagnosed in Japan, how subjects feel about receiving a diagnosis of BE is unclear. We therefore prospectively investigated cancer worry in subjects who received a BE diagnosis. METHODS: Self-administered questionnaires were sent to subjects who were diagnosed with BE at three health checkup institutes in Akita Prefecture, Japan. The cancer worry scale (CWS) was used to quantitatively assess the fear of developing cancer...

Goblet cell adenocarcinoma (GCA) is a rare and distinctive amphicrine tumor comprised of goblet-like mucinous cells and neuroendocrine cells. It is believed to originate from pluripotent stem cells located at the base of crypts. GCA predominantly arises from the appendix, with a few reported cases in extra-appendiceal locations such as the colorectum, small intestine, and stomach. In this case report, we present a unique instance of a 64-year-old male who initially received a diagnosis of neuroendocrine carcinoma in the distal esophagus based on biopsy but, following resection, was subsequently re-diagnosed with GCA arising from Barrett's esophagus...

Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC), and is caused by chronic gastroesophageal reflux. BE can progress over time from metaplasia to dysplasia, and eventually to EAC. EAC is associated with a poor prognosis, often due to advanced disease at the time of diagnosis. However, if BE is diagnosed early, pharmacologic and endoscopic treatments can prevent progression to EAC. The current standard of care for BE surveillance utilizes the Seattle protocol. Unfortunately, a sizable proportion of early EAC and BE-related high-grade dysplasia (HGD) are missed due to poor adherence to the Seattle protocol and sampling errors...

Gastroesophageal reflux disease (GERD) is common, with increasing worldwide disease prevalence and high economic burden. A significant number of patients will remain symptomatic following an empiric proton pump inhibitor (PPI) trial. Persistent symptoms despite PPI therapy are often mislabeled as refractory GERD. For patients with no prior GERD evidence (unproven GERD), testing is performed off antisecretory therapy to identify objective evidence of pathologic reflux using criteria outlined by the Lyon consensus...
