Caused by Trypanosoma cruzi, Chagas disease is responsible for public health problems greater in magnitude than those attributed to malaria, schistosomiasis, or leishmaniasis. A factor in the socioeconomic development of poor countries, Chagas disease can cause death due to a high parasitic burden during its acute phase due and irreversible damage in organs such as the heart, esophagus, and colon during its chronic phase, even when the number of parasites is minimal. For treating Chagas disease, benznidazole (BNZ) remains the drug of choice and, in Latin America, the only drug on the market for treating the disease...

Gastroesophageal reflux disease (GERD) and Barrett's Esophagus (BE), which are prevalent in the World Trade Center (WTC) exposed and general populations, negatively impact quality of life and cost of healthcare. GERD, a risk factor of BE, is linked to obstructive airways disease (OAD). We aim to identify serum biomarkers of GERD/BE, and assess the respiratory and clinical phenotype of a longitudinal cohort of never-smoking, male, WTC-exposed rescue workers presenting with pulmonary symptoms. Biomarkers collected soon after WTC-exposure were evaluated in optimized predictive models of GERD/BE...

BACKGROUND: Catheter ablation for atrial fibrillation has potential to cause esophageal thermal injury. Esophageal temperature monitoring during ablation is commonly used; however, it has not eliminated thermal injuries, possibly because conventional sensors have poor spatial sampling and response characteristics. To enhance understanding of temperature dynamics that may underlie esophageal injury, we tested a high-resolution, intrabody, infrared thermography catheter to continuously image esophageal temperatures during ablation...

BACKGROUND: The association of alcohol intake with the incidence of Barrett's esophagus (BE) has been inconsistent. Although hiatal hernia and male sex are well-known risk factors of BE, its effect on the association of alcohol intake with the incidence of BE remains unknown. AIM: To investigate whether the influence of alcohol intake on the occurrence of BE might differ depending on male sex and presence of hiatal hernia. METHODS: We utilized a database of 8031 patients that underwent upper endoscopy for health screening in a prospective, multicenter, cohort study (the Upper Gastro Intestinal Disease study)...

Gastrointestinal stromal tumors (GISTs) often arise in the stomach and small intestine, while esophageal GISTs are rare. Due to their rarity, clinicopathological data on esophageal GISTs are extremely limited, and this results in a lack of clear recommendations concerning optimal surgical management for esophageal GISTs. It is difficult to distinguish esophageal GIST from leiomyoma, the most frequent esophageal mesenchymal tumor, prior to resection, because the two types of tumors appear similar on computed tomography (CT), endoscopic ultrasound (EUS), and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET)...

Esophageal achalasia is a primary smooth muscle motility disorder specified by aperistalsis of the tubular esophagus in combination with a poorly relaxing and occasionally hypertensive lower esophageal sphincter (LES). These changes occur secondary to the destruction of the neural network coordinating esophageal peristalsis and LES relaxation (plexus myentericus). There are limited data on segmental involvement of the esophagus in adults. We report on the case of a 54-year-old man who presented initially with complete aperistalsis limited to the distal esophagus...

REVIEW
Dennis Yang, Peter V Draganov
OPINION STATEMENT: "Third space" endoscopy, also commonly referred as submucosal endoscopy, is founded on the principle that the deeper layers of the gastrointestinal (GI) tract can be accessed by tunneling in the submucosal space without compromising the integrity of the overlying mucosa. Peroral endoscopic myotomy (POEM), endoscopic submucosal dissection (ESD), and submucosal tunneling endoscopic resection (STER) are innovative techniques within the field of third space endoscopy in the management of esophageal disorders...

BACKGROUND: Systemic sclerosis (scleroderma) is frequently associated with both gastroesophageal reflux disease (GERD) and simultaneous esophageal dysmotility. Anti-reflux procedures in this patient population must account for the existing physiology of each patient and likely disease progression. We aim to compare perioperative and intermediate outcomes of fundoplication versus gastric bypass for the treatment of GERD. METHODS: After IRB approval, patients with systemic sclerosis undergoing fundoplication or gastric bypass for the treatment of GERD from 2004 to 2016 were identified...

BACKGROUND & AIMS: Barrett's Esophagus (BE) is a precursor to esophageal adenocarcinoma (EAC). Guidelines recommend that patients with nondysplastic BE (NDBE) undergo surveillance endoscopy every 3-5 years. We aimed to identify factors associated with surveillance endoscopy of patients with NDBE and identify trends in appropriate surveillance endoscopy of NDBE at a large tertiary care center. METHODS: We performed a retrospective analysis of data from a Barrett's Esophagus Registry, identifying patients with NDBE who underwent endoscopy in 2002 or later...

BACKGROUND: Adult schistosomes have a well-developed alimentary tract comprising an oral sucker around the mouth, a short esophagus and a blind ending gut. The esophagus is not simply a muscular tube for conducting blood from the mouth to gut but is divided into compartments, surrounded by anterior and posterior glands, where processing of ingested blood is initiated. Self-cure of rhesus macaques from a Schistosoma japonicum infection appears to operate by blocking the secretory functions of these glands so that the worms cease feeding and slowly starve to death...

Stem cells are defined by their capacities to self-renew and generate progeny of multiple lineages. The transcription factor SOX2 has key roles in the regulation of stem cell characteristics, but whether SOX2 achieves these functions through similar mechanisms in distinct stem cell populations is not known. To address this question, we performed RNA-seq and SOX2 ChIP-seq on embryonic mouse cortex, spinal cord, stomach and lung/esophagus. We demonstrate that, although SOX2 binds a similar motif in the different cell types, its target regions are primarily cell-type-specific and enriched for the distinct binding motifs of appropriately expressed interacting co-factors...

Gastroesophageal cancer is the sixth leading cause of cancer-related death worldwide. The 2 most common histologies are squamous cell carcinoma and adenocarcinoma, which has seen an increase in incidence correlating with an increase in obesity in developed countries. Gastroesophageal adenocarcinoma has a preponderance to metastasize early, making it a highly lethal cancer with a low 5-year survival rate of ∼15-25%. Therefore, for the majority of patients, treatment focuses on palliation and prolongation of survival...
