The effects of tranexamic acid on the histopathology of defect healing in an porcine model after gastric and colonic endoscopic submucosal dissection.

Introduction: There is limited data on the histopathological effects of hemostatic agents (HAs) used during endoscopic submucosal dissection (ESD). We used an porcine model to compare the tissue effects of tranexamic acid (TXA) and adrenaline (epinephrine) compared to controls.

Methods: Standard ESD, using a 2 mm flash-knife, was performed in three pigs.

Sedation and Endoscopy-Assisted High-Resolution Manometry (SEA-HRM) in Patients Who Previously Failed Standard Esophageal Manometry.

Esophageal high-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders, but it may be poorly tolerated and unsuccessful. We sought to evaluate a protocol for sedation and endoscopy-assisted (SEA) HRM in patients who previously failed standard HRM and assess patient perspectives towards it. Adult patients who previously failed HRM were prospectively enrolled.

Evaluation of Acute Terminal Ileitis in Hospitalized Patients: Development of a Predictive Model to Distinguish Crohn's Disease from Other Etiologies.

: Terminal ileitis (TI) is often identified on CT scans in emergency settings. Diagnosing Crohn's disease (CD) as a cause of TI is crucial due to its significant long-term implications. This study aimed to differentiate CD from other causes of acute TI and develop a predictive model for CD diagnosis.

Prior abdominal surgery as a potential risk factor for colonic diverticulosis or diverticulitis.

Background: Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions and these may lead to increased intraluminal colonic pressure.

Aim: To assess whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis.

A Novel Model to Predict Inadequate Bowel Preparation Prior to Colonoscopy Incorporating Patients' Reactions to Drinking the Laxative.

Background And Aims: Prior studies have identified predictors of inadequate preparation with limited success. We aimed to build a model that could predict the likelihood of inadequate preparation by also including factors related to the patient's reaction to drinking the laxative preparation.

Methods: Demographic, clinical, and preparation-related data were prospectively collected on patients undergoing colonoscopy.

Technical Success in Performing Esophageal High-Resolution Manometry in Patients with an Epiphrenic Diverticulum.

High-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders, yet it can be poorly tolerated and technically challenging. Epiphrenic diverticula (ED) are located in the distal esophagus and are associated with underlying motility disorders. ED patients (2008-2022) were retrospectively compared to achalasia patients (2008-2022) and all other patients (2021-2022) who underwent HRM at a single center.

Predictors of Underlying Esophageal Motility Disorders in Patients Presenting with Esophageal Candidiasis.

Objectives: Esophageal motility disorders (EMDs) are a known risk factor for esophageal candidiasis (EC), but this relation has not been described particularly well. We sought to evaluate the predictors of underlying EMDs in patients presenting with EC.

Methods: Cases of EC at a single medical center between 2010 and 2021 were identified retrospectively based on the code.

Ethnic Differences in Anorectal Manometry Findings in Patients With Fecal Incontinence: Results From a Multiethnic Cohort According to the London Classification.

Background/aims: Clinical rates of fecal incontinence (FI) are known to vary based on race and ethnicity. It is unclear if anorectal manometry (ARM) findings in patients with FI differ based on ethnicity.

Methods: High-resolution ARM studies performed between 2014-2021 due to FI at 2 hospitals with multiethnic populations were retrospectively reviewed.

Correlation between Lower Esophageal Sphincter Metrics on High-Resolution Manometry and the Clinical Presentation of Patients with Newly Diagnosed Achalasia.

Background: Achalasia is characterized by aperistalsis with poor relaxation of the lower esophageal sphincter (LES). We aimed to systematically assess whether LES metrics on high-resolution manometry (HRM) correlate with the symptomatic or endoscopic presentation of patients with achalasia.

Methods: A retrospective study was performed at two tertiary medical centers.

Integrated Relaxation Pressure (IRP) Distinguishes between Reflux-Predominant and Dysphagia-Predominant Phenotypes of Esophageal "Absent Contractility".

Background: Patients with absent contractility (AC) often suffer from either reflux or dysphagia. It remains unclear what factors determine which phenotype patients present with. We sought to evaluate if high-resolution manometry metrics, especially integrated relaxation pressure (IRP), could explain this.

Video Capsule Endoscopy Has a Minor Long-term Therapeutic Impact on Patients with Iron Deficiency Anemia.

Background: One of the main causes of iron deficiency anemia (IDA) is chronic gastrointestinal blood loss. The use of video capsule endoscopy (VCE) after negative bidirectional endoscopy in patients with IDA is controversial.

Objectives: To evaluate the effect of VCE in the management and long-term outcomes of IDA patients.

The Natural History of Esophageal "Absent Contractility" and Its Relationship with Rheumatologic Diseases: A Multi-Center Case-Control Study.

(1) Background: Absent contractility (AC) is an esophageal motility disorder defined as a normal integrated relaxation pressure with 100% failed peristalsis. We sought to clarify the natural history of this disorder and its relationship with rheumatologic diseases, such as systemic sclerosis (scleroderma). (2) Methods: We retrospectively identified patients with AC based on high-resolution manometry findings at three referral institutions and then matched them with controls with esophageal complaints who had normal manometries.

The effect of direct-acting antiviral regimens and telemedicine on the treatment of inmates with hepatitis C virus infection in Israeli prisons.

Background: Direct-acting antiviral (DAA) regimens and telemedicine services are both options for treating hepatitis C virus (HCV) within the prison setting. We aimed to compare factors associated with HCV treatment success over the past decade in Israeli prisons, specifically the influence of DAAs and telemedicine.

Methods: We retrospectively reviewed the medical records of inmates with HCV infection in Israeli prisons from 2010 through 2020.

The Effect of a Didactic Course on Gastroenterology Nurses' Knowledge and Interest in Anorectal Manometry.

Anorectal manometry may be performed by a nurse or physician, yet little has been written about what training is needed. Additionally, many gastroenterology nurses receive little exposure to motility studies such as anorectal manometry, limiting their ability to learn these procedures. We therefore sought to evaluate whether a short didactic course on anorectal manometry would increase nurses' knowledge about the procedure and stimulate their interest in becoming trained to perform it.

Real world management of esophageal ulcers: analysis of their presentation, etiology, and outcomes.

Background And Study Aims: Esophageal ulcers are a rare cause of upper gastrointestinal morbidity and may be due to different etiologies. We sought to systematically evaluate patients with esophageal ulcers and describe their presentations, endoscopic findings, etiologies, treatments, and outcomes.

Patients And Methods: Patients diagnosed with esophageal ulcers over an 11-year period were retrospectively identified from our institution's electronic medical records.

Effect of inflammatory bowel disease and related medications on COVID-19 incidence, disease severity, and outcome: the Israeli experience.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic raised concerns among inflammatory bowel disease (IBD) patients fearing an increased risk of infection and poor outcomes. We aimed to evaluate the incidence of COVID-19 among IBD patients; its influence on disease severity and outcome; its relationship to medication use and how the pandemic affected IBD management.

Methods: An anonymous questionnaire was posted online to members of the Israel Crohn's Disease and Ulcerative Colitis Foundation (November 2020-January 2021).

New-Onset of Crohn's Disease Is Associated with Antistreptolysin O Positive Titers.

Objective: Different infectious agents have been presumed to be candidates acting as an etiologic factor or trigger of Crohn's disease (CD). Group A (GAS) is a common human infection agent that can also trigger post-infectious immune-mediated conditions. The current study aimed to examine whether the immunogenic activity induced by GAS may trigger new-onset of CD.
