The stratified squamous epithelium of the esophagus shows a proliferative basal layer of keratinocytes that undergo terminal differentiation in overlying suprabasal layers. Esophageal pathologies, including eosinophilic esophagitis, gastroesophageal reflux disease, Barrett's esophagus, squamous cell carcinoma, and adenocarcinoma, cause perturbations in the esophageal epithelial proliferation-differentiation gradient. Three-dimensional (3D) culture platforms mimicking in vivo esophageal epithelial tissue architecture ex vivo have emerged as powerful experimental tools for the investigation of esophageal biology in the context of homeostasis and pathology...

BACKGROUND: An association between inlet patches and proximal esophageal adenocarcinomas is currently suspected because of numerous case reports of simultaneous occurrence of both diseases. AIMS: To analyze whether inlet patches are significantly associated with proximal esophageal adenocarcinomas in a large population. METHODS: Computerized search of pathology and EGD reports revealed 398 cases of esophageal adenocarcinomas among 156,236 EGDs (performed on 106,510 patients) diagnosed by histopathology performed at Royal Oak/Troy, William Beaumont Hospitals, 2003-2016...

Endoscopic optical coherence tomography (OCT) has emerged as a valuable tool for advancing our understanding of the histomorphology of various internal luminal organs and studying the pathogenesis of relevant diseases. To date, this technology affords limited resolving power for discerning subtle pathological changes associated with early diseases. In addition, it remains challenging to access small luminal organs or pass through narrow luminal sections without potentially causing trauma to tissue with a traditional OCT endoscope of a 1-1...

A multi-LU-domain-containing protein denoted C4.4A exhibits a tightly regulated membrane-associated expression in the suprabasal layers of stratified squamous epithelia such as skin and the esophagus, and the expression of C4.4A is dysregulated in various pathological conditions. However, the biological function of C4.4A remains unknown. To enable further studies, we evaluated the expression of C4.4A in monolayer cultures of normal human keratinocytes and in tissue-engineered skin substitutes (TESs) produced by the self-assembly approach, which allow the formation of a fully differentiated epidermis tissue...

PURPOSE OF REVIEW: To summarize the literature regarding appropriate endoscopic sampling and surveillance protocols for common inflammatory diseases of the digestive tract. Gastroenterologists increasingly use endoscopy with mucosal biopsy to detect inflammatory diseases, assess response to therapy, and monitor for progression to dysplasia. RECENT FINDINGS: Many diseases show a patchy distribution in the digestive tract and there may be poor correlation between the endoscopic appearance and presence of histologic abnormalities...

Introduction. Button battery ingestion is considered an emergency situation in pediatric patients that needs to be managed promptly; otherwise, it may lead to serious and potentially lethal complications, especially when it is impacted in the esophagus. Less attention has been given in cases where the battery passes into the stomach, with guidelines for emergency intervention being based on the presence of symptoms. Case Report. We present a case of an 18-month-old male patient who presented to our emergency department after button battery ingestion...

INTRODUCTION: Fibrovascular polyps (FVPs) are benign tumors that commonly occur in the cervical esophagus. Few cases of FVPs of the hypopharynx have been reported, but there has been no English review concerning hypopharyngeal FVPs (hFVPs). Here, we report a case of a vast hFVP, and we also review 13 hFVP cases found in the English literature (PubMed search) including our case. CASE DESCRIPTION: A 41-year-old man with respiratory distress and regurgitation of a mass was referred to our hospital...

Patrick J McLaren, James P Dolan
In recent years, a number of endoluminal procedures such as endoscopic resection and thermal ablation have emerged as less invasive treatment options for early esophageal cancer. These therapies have demonstrated excellent oncologic outcomes for dysplasia as well as intramucosal cancers. However, few studies have directly compared long-term outcomes of endoscopic therapy versus traditional esophagectomy. Current esophagectomy techniques now deliver consistently good outcomes in the hands of experienced surgeons at high volume centers, and this option should be considered an important treatment consideration for early esophageal cancer...

Esophageal cancer (EC) is the most invasive disease associated with inclusive poor prognosis. EC usually is found as either adenocarcinoma (EAC) or squamous cell carcinomas (ESCC). ESCC forms in squamous cells and highly occurs in the upper third of the esophagus. EAC appears in glandular cells and ordinarily develops in the lower one third of the esophagus near the stomach. Barrett's esophagus (BE) is a metaplastic precursor of EAC. There is a persistent need for improving our understanding of the molecular basis of this disease...

Leiomyomas of the gastrointestinal tract are mostly found in the esophagus, stomach, and colon. Genetic information about them is very limited and no fusion genes have been described. We present herein cytogenetic and molecular genetic analyses of two gastrointestinal leiomyomas found in the esophagus and small intestine. The esophageal leiomyoma had the karyotype 45,Y,der(X)t(X;6)(p22;p21),inv(2)(p23q35),add(6)(p21),-11[cp6]/46,XY[7].

BACKGROUND: Most of benign esophageal strictures caused by gastroesophageal reflux are short segments and can be treated by an endoscopic dilatation, but cases of long-segment stenosis requiring an esophagectomy are rare. CASE PRESENTATION: A 62-year-old woman had undergone emergency surgery for a giant ovarian tumor rupture at another hospital. A duodenal perforation occurred after surgery but improved with conservative treatment. She had undergone long-term nasogastric tube placement for 4 months because she was on a mechanical ventilator and did not receive proton pump inhibitors (PPIs)...

BACKGROUND: Eosinophilic esophagitis (EoE) is a rapidly emerging, chronic inflammatory, genetically impacted disease of the esophagus, defined clinically by symptoms of esophageal dysfunction and, pathologically, by an eosinophil-predominant tissue infiltration. However, in four EoE families, we have identified patients presenting with EoE-typical and corticosteroid-responsive symptoms, but without tissue eosinophilia. The aim of this study was to clinically and immunologically characterize these patients with EoE-like disease...

INTRODUCTION: Endoscopic therapy has revolutionized the treatment of Barrett's esophagus with high-grade dysplasia (HGD) or intramucosal adenocarcinoma by allowing preservation of the esophagus in many patients who would previously have had an esophagectomy. This paradigm shift initially occurred at high-volume centers in North America and Europe but now is becoming mainstream therapy. There is a lack of uniform guidelines and algorithms for the management of these patients. Our aim was to review important concepts and pitfalls in the endoscopic management of superficial esophageal adenocarcinoma...

A 62-year-old woman, who had dysesthesia in the throat, and polyposia the previous year, was admitted in a coma because of respiratory failure. Computed tomography scans demonstrated dilatation of the esophagus and stenosis of the trachea. After emergency intubation, extubation was not possible due to a collapsed trachea, so we performed a tracheostomy. The tracheoscopy from the stoma showed an esophagus-like trachea due to disappearance of the tracheal cartilage and the straight pattern on the membranous portion, and the lumen deformed with coughing...
