Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
Underlying the epithelium is the lamina propria, which contains myofibroblasts, blood vessels, nerves, and several different immune cells, and the muscularis mucosa which is a layer of smooth muscle that aids in the action of continued peristalsis and catastalsis along the gut.
Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion" in this context means damage that is limited to the mucosa, which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), the basement membrane, and the lamina propria.
Reactive gastropathy is morphologically distinct entity [3] [4] that can be separated from gastritis, which by definition has a significant inflammatory component.. As a reactive gastropathy may mimic a (true) gastritis symptomatically and visually in an endoscopic examination, it may incorrectly be referred to as a gastritis.
In humans, it is about one mm thick, and its surface is smooth, soft, and velvety. It consists of simple secretory columnar epithelium, an underlying supportive layer of loose connective tissue called the lamina propria, and the muscularis mucosae, a thin layer of muscle that separates the mucosa from the underlying submucosa.
The afflicted colon's histologic findings include thickening of the muscularis propria, submucosal fibrosis, a cobblestone-like appearance, and persistent mucosal inflammation. [8] With relative rectal sparing, imaging can demonstrate diffuse narrowing, shortening, and loss of haustration of the colonic lumen.
CT abdomen, coronal section, showing characteristic large rugal folds in the stomach. A cyst is also seen in the liver. The large folds of the stomach, as seen in Ménétrier disease, are easily detected by x-ray imaging following a barium meal or by endoscopic methods. Due to the thickened rugae folds, it is said to have a cerebriform (brain ...
