Heterotopic gastric mucosa in the upper esophagus: a prospective study of 33 cases and review of literature

Endoscopy
E Jacobs, M F Dehou

Abstract

The prevalence of endoscopically diagnosed heterotopic gastric mucosa in the upper esophagus (HGMUE) has been reported in a few studies, and varies from 0.1 to 10%. Clinical relevance and possible association with other pathological conditions remain a matter of debate. A prospective study was carried out to determine the prevalence of HGMUE, the influence on it of age and sex, and to study the macroscopic and microscopic aspects of the lesion, its clinical relevance and possible association with other pathological conditions. A total of 674 new patients with upper digestive complaints or alteration of their state of health underwent upper gastrointestinal endoscopy, with special attention paid to the proximal esophagus when withdrawing the gastroscope. They had been carefully questioned, especially regarding possible complaints, which could have drawn attention to the upper esophagus. Heterotopic columnar epithelium in the proximal esophagus was found in 4.9 % of patients. No difference was observed according to age or sex. A mild to moderate chronic inflammatory infiltration of the heterotopic patch was observed in most cases, not related to the presence in the lesion of Helicobacter pylori, which was found in only one case. ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
