Mucosal Barrier of the Stomach

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Histology of the Large Intestine

Histology of the Large Intestine

The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

Histology of the Small Intestine

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Peptic Ulcer

Peptic Ulcer

Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...

Histology of the Gastrointestinal (GI) Tract

Histology of the Gastrointestinal (GI) Tract

The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

Poliomyelitis

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Summary

A rare enteric muco-submucosal elongated polyp (EMSEP) was found in the jejunum and successfully removed via endoscopic polypectomy. Further research is needed to understand EMSEP and its relation to colonic counterparts.

Area of Science:

Gastroenterology
Endoscopy
Pathology

Background:

Colonic muco-submucosal elongated polyps (CMSEP) are rare, long, and slender lesions.
Similar lesions outside the colon are exceptionally uncommon.

Observation:

A case of enteric muco-submucosal elongated polyp (EMSEP) was identified in the jejunum.
The EMSEP was determined to be the source of gastrointestinal bleeding.

Findings:

Endoscopic polypectomy using double balloon enteroscopy (DBE) was performed to remove the bleeding EMSEP.
Histological examination of the resected specimen showed features consistent with CMSEP.

Implications:

Advancements in enteroscopy may increase the detection rate of EMSEPs.
Further investigation is required to elucidate the similarities and differences between CMSEPs and EMSEPs.
