Barrett's esophagus is the metaplastic change of the squamous epithelium lining the distal esophagus into an intestinalized columnar epithelium that predisposes to esophageal adenocarcinoma development. The cell that gives rise to Barrett's esophagus has not been identified definitively, although several sources for the Barrett's esophagus cell of origin have been postulated. One possible source is a fully differentiated squamous epithelial cell or a squamous epithelial progenitor or stem cell native to the esophagus that, through molecular reprogramming, either transdifferentiation or transcommitment, could give rise to an intestinalized columnar cell...

INTRODUCTION: Patients with esophageal cancer frequently cannot tolerate thoracotomy due to their overall debilitated condition. Moreover, some patients have severe adhesions in the thoracic cavity. Eversion stripping of the esophagus is an option for resection in these patients. PRESENTATION OF CASE: A 64-year-old man was admitted to our institution with the chief complaint of epigastric pain. Endoscopic examination showed a protruding lesion 22cm from the incisors, with a superficial and circumferential mucosal irregularity on the distal side of the lesion...

Esophageal cancer is a serious malignancy with high mortality. The two common distinctive pathologic subtypes of esophageal cancer are squamous cell carcinoma and adenocarcinoma. These differ with regards to etiology, ethnic distribution, pathogenesis, and location in the esophagus. The precursor lesions are also unique to each subtype. Squamous cell carcinoma is more common in East Asia, is linked to smoking and tobacco use, more commonly involves the middle esophagus, and the precursor lesion is squamous dysplasia...

Esophagogastric landmarks are recognizable in the same way both in children and in adults, and palisade-shaped vessels can be observed at the distal position of esophageal mucosa, even in infants. Few studies have been done in respect to Barrett's esophagus (BE) in children. Incidence of endoscopically suspected BE among all children undergoing esophagogastroduodenoscopy (EGD) is approximately 0.25-1.4%, but can be up to 9.7% in patients with gastroesophageal reflux disease (GERD). Some data suggest that BE is an acquired disorder and point to the possibility of a congenital component in combination with severe mucosal injury...

Gastroesophageal reflux disease (GERD) clinically predisposes to columnar Barrett's metaplasia (BM) in the distal esophagus. We demonstrate evidence supporting the cellular origin of BM from reprograming or transcommitment of resident normal esophageal squamous (NES) epithelial cells in response to acid and bile (A + B) exposure using an in vitro cell culture model. The hTERT-immortalized NES cell line NES-B10T was exposed 5 min/day to an A + B mixture for 30 wk. Morphological changes, mRNA, and protein expression levels for the inflammatory marker cyclooxygenase-2; the lineage-determining transcription factors TAp63 (squamous), CDX2, and SOX9 (both columnar); and the columnar lineage markers Villin, Muc-2, CK8, and mAb Das-1 (incomplete phenotype of intestinal metaplasia) were assessed every 10 wk...

Extracorporeal Membrane Oxygenation (ECMO) for repair of tracheal injury during transhiatal esophagectomy Tracheal injury is a rare but potentially fatal complication of esophagectomies requiring prompt recognition and treatment. We describe a case of tracheal injury recognized in the operative period of an open transhiatal esophagectomy for squamous cell carcinoma of the mid to distal esophagus. When injury was discovered, attempts to improve oxygenation and ventilation by conventional methods were unsuccessful...

INTRODUCTION: Esophageal cancer (EC) and human immunodeficiency virus (HIV) are common in parts of South Africa. Squamous cell carcinoma of the esophagus in KwaZulu-Natal, South Africa presents generally in advanced stages and is mostly palliated by the deployment of self-expandable metal stent (SEMS). This study analyses these relationships between coexistent HIV infection, SEMS deployment, and survival scores. METHODOLOGY: Information on patients managed with SEMS between October 2013 and December 2014 was retrieved from a prospective database of EC and followed up until April 2015...

Verrucous carcinoma is a rare, slow-growing type of squamous cell cancer. Fewer than 50 patients with verrucous carcinoma in the esophagus have been described worldwide. In 2014, two male patients were diagnosed with verrucous carcinoma in the distal part of the esophagus. The endoscopic examinations showed a similar wart-like, white, irregular mucosa in both cases. The diagnosis was difficult to make since all biopsies taken from the affected area showed no malignancy. This cancer type has a relatively good prognosis when the diagnosis is finally obtained...

Esophageal squamous cell carcinoma (ESCC) is the commonest primary malignant esophageal tumor, which typically presents as endoscopically visible surface mucosal ulcerations, irregularities, or polyploidal masses. We here report a rare case of primary ESCC with completely intramural growth under a normal looking intact nondysplastic surface squamous epithelium disguising as a submucosal tumor. Upper gastrointestinal endoscopy-guided mucosal biopsy was negative for malignancy. Endoscopic ultrasound (EUS) revealed a heteroechoic solid mass originating from the muscularis propria of the distal esophagus...

A 57-year-old man with a past medical history of total laryngectomy for squamous cell carcinoma of the larynx was admitted to our institution 5 months after the procedure, for surgical resection of a local recurrence of the tumor. In the postoperative period, endoscopically guided placement of a nasogastric tube was scheduled, after previous failed attempts. Upper gastrointestinal endoscopy revealed an anastomotic dehiscence, 13 cm distal to the incisors, and a foreign body penetrating through the esophageal wall, 20cm distal to the incisors...

BACKGROUND AND OBJECTIVE: Diagnosis of esophageal diseases is often hampered by sampling errors that are inherent in endoscopic biopsy, the standard of care. Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal endomicroscopy technology that has the potential to visualize cellular features from large regions of the esophagus, greatly decreasing the likelihood of sampling error. In this paper, we report results from a pilot clinical study imaging the human esophagus in vivo with a prototype SECM endoscopic probe...

Barrett's esophagus is the condition in which metaplastic columnar epithelium that predisposes to cancer development replaces stratified squamous epithelium in the distal esophagus. Potential sources for the cell or tissue of origin for metaplastic Barrett's epithelium are reviewed including native esophageal differentiated squamous cells, progenitor cells native to the esophagus located within the squamous epithelium or in the submucosal glands or ducts, circulating bone marrow-derived stem cells, and columnar progenitor cells from the squamocolumnar junction or the gastric cardia that proximally shift into the esophagus to fill voids left by damaged squamous epithelium...

Barrett's esophagus (BO) is a preneoplastic condition described as the replacement of the stratified squamous epithelium of the distal esophagus with one that histologically presents as a diverse mixture of metaplastic glands resembling gastric or intestinal-type columnar epithelium. The clonal origins of BO are still unclear. More recently, we have begun to investigate the relationship between the various metaplastic gland phenotypes observed in BO, how they evolve, and the cancer risk they bestow. Studies have revealed that glands along the BO segment are clonal units containing a single stem cell clone that can give rise to all the differentiated epithelial cell types in glands...

Exciting new developments-pharmacologic, endoscopic, and surgical-have arisen for the treatment of many esophageal diseases. Refractory gastroesophageal reflux disease presents a therapeutic challenge, and several new options have been proposed to overcome an insufficient effectiveness of proton pump inhibitors. In patients with distal esophageal spasm, drugs and endoscopic treatments are the current mainstays of the therapeutic approach. Treatment with proton pump inhibitors (or antireflux surgery) should be considered in patients with Barrett's esophagus, since a recent meta-analysis demonstrated a 71% reduction in risk of neoplastic progression...

In the present study, clips were used as markers to evaluate displacement differences between proximal and distal ends of esophageal tumors and to test whether their internal target volume (ITV) margins should be determined separately. A total of 23 patients with mid-upper thoracic esophageal squamous-cell carcinoma, a tumor length of ≤8 cm and an esophageal lumen suitable for endoscopic ultrasonography were recruited for the present study. Clips were implanted endoscopically at the proximal and distal ends of the esophageal tumor (upper and lower clips)...

BACKGROUND: Esophagectomy may lead to impairment in gastric emptying unless pyloric drainage is performed. Pyloric drainage may be technically challenging during minimally invasive esophagectomy and can add morbidity. We sought to determine the effectiveness of intraoperative endoscopic injection of botulinum toxin into the pylorus during robotic-assisted esophagectomy as an alternative to surgical pyloric drainage. MATERIALS AND METHODS: We performed a retrospective analysis of patients with adenocarcinoma and squamous cell carcinoma of the distal esophagus or gastroesophageal junction who underwent robotic-assisted transhiatal esophagectomy (RATE) without any surgical pyloric drainage...
