esophagus development

Anastomotic leakage (AL) is a dreaded complication following esophageal resection. No clear consensus exist for the optimal handling of this severe complication. The aim of this study was to describe the treatment outcome following AL. We conducted a retrospective cross-sectional study including all patients with AL operated with Ivor Lewis esophagectomy from 2010 to 2021 at Oslo University Hospital, Norway. 74/526 (14%) patients had AL. Patient outcomes were analyzed and categorized according to main AL treatment strategy; stent (54%), endoscopic vacuum therapy and stent (EVT + stent) (19%), nasogastric tube and antibiotics (conservative) (16%), EVT (8%) and by other endoscopic means (other) (3%)...

BACKGROUND: Gut microbiota(GM) have been proven associated with lots of gastrointestinal diseases, but its causal relationship with Gastroesophageal reflux disease(GERD) and Barrett's esophagus(BE) hasn't been explored. We aimed to uncover the causal relation between GM and GERD/BE and potential mediators by utilizing Mendelian Randomization(MR) analysis. METHODS: Summary statistics of GM(comprising 301 bacteria taxa and 205 metabolism pathways) were extracted from MiBioGen Consortium(N = 18,340) and Dutch Microbiome Project(N = 7,738), GERD and BE from a multitrait meta-analysis(NGERD =602,604, NBE =56,429)...

Exosomes are small extracellular vesicles (30-150 nm) that are formed by endocytosis containing complex RNA as well as protein structures and are vital in intercellular communication and can be used in gene therapy and drug delivery. According to the cell sources of origin and the environmental conditions they are exposed to, these nanovesicles are very heterogeneous and dynamic in terms of content (cargo), size and membrane composition. Exosomes are released under physiological and pathological conditions and influence the pathogenesis of cancers through various mechanisms, including angiogenesis, metastasis, immune dysregulation, drug resistance, and tumor growth/development...

BACKGROUND: Gastrointestinal (GI) dysfunction is a common non-motor feature of Parkinson disease (PD). GI symptoms may start years before the onset of motor symptoms and impair quality of life. Robust clinical trial data is lacking to guide screening, diagnosis and treatment of GI dysfunction in PD. OBJECTIVE: To develop consensus statements on screening, diagnosis, and treatment of GI dysfunction in PD. METHODS: The application of a modified Delphi panel allowed for the synthesis of expert opinions into clinical statements...

Consensus statement on smoking and vascular risk About 22% of the Spanish population are daily smokers. Men are more likely to smoke than women. In Spain, women between 15-25 years of age smoke as much or more than men. Every smoker should be assessed for: physical dependence on nicotine (Fagerström test), social and psychological dependence (Glover Nilsson test), level of motivation to quit (Richmond test), probability of therapy success (Henri-Mondor and Michael-Fiore tests), and stage of behavioral change development (Prochaska and DiClementi)...

PURPOSE: To identify the biodistribution and diagnostic performance of a novel fibroblast activation protein (FAP) targeted positron emission tomography (PET) tracer, [68 Ga]Ga-DOTA-GPFAPI-04, in patients with solid tumors in a head-to-head comparison with [18 F]F-FDG. METHODS: Twenty-six patients histologically proven with cancers of nasopharyngeal (n = 5), esophagus (n = 5), gastro-esophagus (n = 1), stomach (n = 7), liver (n = 3), and colorectum (n = 5) were recruited for [68 Ga]Ga-DOTA-GPFAPI-04 and [18 F]F-FDG PET/CT scans on consecutive days...

INTRODUCTION: We conducted a meta-analysis evaluating the overall risk of esophageal adenocarcinoma (EAC) in individuals with Helicobacter pylori infection, and a network meta-analysis to assess the role of H. pylori infection in the progression from Barrett's esophagus (BE) to EAC. EVIDENCE ACQUISITION: The MEDLINE, EMBASE and Cochrane databases were searched between 1988 and June 2023 for observational studies of H. pylori infection and the risk of EAC. Summary odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using the DerSimonian-Laird method...

IL-36 cytokines are emerging as beneficial in immunity against pathogens and cancers but can also be detrimental when dysregulated in autoimmune and autoinflammatory conditions. Interest in targeting IL-36 activity for therapeutic purposes is rapidly growing, yet many unknowns about the functions of these cytokines remain. Thus, the availability of robust research tools is essential for both fundamental basic science and pre-clinical studies to fully access outcomes of any manipulation of the system. For this purpose, a floxed Il1rl2 , the gene encoding the IL-36 receptor, mouse strain was developed to facilitate the generation of conditional knockout mice...

INTRODUCTION: The prevalence of Barrett's esophagus (BE) in France is unknown. However, the management of dysplastic BE in expert centers is recommended and reduces the risk of developing invasive adenocarcinoma. Our aim was to determine the burden of BE patients in the Paris Region. METHODS: We performed a retrospective study using the data from electronic medical records from the data warehouse of the 39 Greater Paris public hospitals (Entrepôt de données de santé de l' Assistance Publique- Hôpitaux de Paris) for the year 2018, and used natural language processing to search for occurrences of Barrett's esophagus in endoscopy and pathology reports...

BACKGROUND: Real-world clinical outcomes of and prognostic factors for nivolumab treatment for esophageal squamous-cell carcinoma (ESCC) remain unclear. This study aimed to evaluate real-world outcomes of nivolumab monotherapy in association with relevant clinical parameters in recurrent/unresectable advanced ESCC patients. METHODS: This population-based multicenter cohort study included a total of 282 patients from 15 institutions with recurrent/unresectable advanced ESCC who received nivolumab as a second-line or later therapy between 2014 and 2022...

PURPOSE: Systemic Sclerosis (SSc) is a rare connective tissue disorder characterized by autoimmunity, fibrosis, and vasculopathy that affects the skin and internal organs, including the gastrointestinal tract, particularly the esophagus. This article highlights the characteristics and clinical symptoms of esophageal involvement in patients with SSc. PATIENTS AND METHODS: This study was conducted between November 2022 to August 2023, including 26 already diagnosed cases of SSc in the Department of Rheumatology and Rehabilitation and Kurdistan Center for Gastroenterology and Hepatology-Sulaymaniyah, Iraq...

BACKGROUND AND OBJECTIVE: Barrett's esophagus (BE) is a precancerous condition that has the potential to develop into esophageal cancer (EC). Currently, there is a wide range of management options available for individuals at different pathological stages in Barrett's esophagus (BE). However, there is currently a lack of knowledge regarding their comparative efficacy. To address this gap, we conducted a network meta-analysis of published randomized controlled trials to examine the comparative effectiveness of all regimens...

BACKGROUND & AIM: Esophageal varices (EV) screening guidelines have evolved with improved risk stratification to avoid unnecessary esophagogastroduodenoscopy (EGD) in individuals with low bleeding risks. However, uncertainties persist in the recommendations for certain patient groups, particularly those with hepatocellular carcinoma (HCC) and/or receiving non-selective beta-blockers (NSBB) without prior endoscopy. This study assessed the efficacy of imaging in ruling out EVs and their high-risk features associated with bleeding in patients with cirrhosis and with HCC...

Background and Aim Surveillance of non-dysplastic Barrett's esophagus (BE) is recommended to identify progression to dysplasia; however, the most cost-effective strategy remains unclear. Mutation or aberrant expression of p53 has been associated with the development of dysplasia in BE. We sought to determine if surveillance intervals for BE could be stratified based on p53 expression. Methods A Markov model was developed for non-dysplastic BE. Patients with non-dysplastic BE (NDBE) underwent p53 immunohistochemistry (IHC) and those with abnormal p53 expression underwent surveillance endoscopy at 1 year, whilst patients with normal p53 expression underwent surveillance in 3 years...

BACKGROUND: The treatment of patients with end-stage achalasia with a sigmoid-shaped esophagus is particularly challenging. A modified technique (pull-down technique) has been developed to straighten the esophageal axis, but only a limited number of studies on this topic are available in the literature. This study aimed to compare the outcome of patients who underwent the pull-down technique with that of patients who had a classical laparoscopic Heller-Dor (CLHD) myotomy. METHODS: All patients with a radiologic diagnosis of end-stage achalasia who underwent an LHD myotomy between 1995 and 2022 were considered eligible for the study...

The pathophysiologies of achalasia and gastroesophageal reflux disease with Barrett's esophagus are highly distinct, though the clinical signs and symptoms of both are highly overlapped. The concomitant development of both achalasia and Barrett's esophagus is rare. We describe a case of a patient with a concomitant diagnosis of both pathologies and further explain the epidemiology of carrying both diseases simultaneously.

Objectives: Resveratrol has been implicated in the differentiation and development of human umbilical cord mesenchymal stem cells. The differentiation of into esophageal fibroblasts is a promising strategy for esophageal tissue engineering. However, the pharmacological effect and underlying mechanism of resveratrol on human umbilical cord mesenchymal stem cells differentiation are unknown. Here, we investigated the effects and mechanism of resveratrol on the differentiation of human umbilical cord mesenchymal stem cells...

INTRODUCTION AND IMPORTANCE: Lusory dysphagia (LD) is a rare disorder resulting from extrinsic vascular compression of the esophagus, is often associated with an aberrant right subclavian artery (ARSA). LD is characterized by abnormal development of the right fourth aortic arch during embryonic stages, leading to posterior coursing of the artery in 80 % of cases. Predominantly presenting as dysphagia, LD can occasionally manifest with laryngeal stridor or dyspnea, yet it often remains asymptomatic and incidentally discovered...

BACKGROUND: The aim of the study was to establish a weighted comprehensive evaluation model (WCEM) of image registration for cone-beam computed tomography (CBCT) guided lung cancer radiotherapy that considers the geometric accuracy of gross target volume (GTV) and organs at risk (OARs), and assess the registration accuracy of different image registration methods to provide clinical references. METHODS: The planning CT and CBCT images of 20 lung cancer patients were registered using diverse algorithms (bony and grayscale) and regions of interest (target, ipsilateral, and body)...

Eosinophilic esophagitis (EoE) and gastroesophageal reflux disease (GERD) share many histopathological features; therefore, markers for differentiation are of diagnostic interest and may add to the understanding of the underlying mechanisms. The nitrergic system is upregulated in GERD and probably also in EoE. Esophageal biopsies of patients with EoE (n = 20), GERD (n = 20), and healthy volunteers (HVs) (n = 15) were exposed to antibodies against inducible nitric oxide synthase (iNOS), nitrotyrosine, eosinophilic peroxidase, eotaxin-3, and galectin-3...
