What is pyloric mucosal diaphragm?

What is pyloric mucosal diaphragm?

Abstract. Fifty-six adult patients with antral mucosal diaphragms have been reported in the literature. These abnormalities are located at the antrum of the stomach at variable distances from the pylorus and are composed of mucosa which encloses a membrane of submucosa without involvement of muscularis or serosa.

Does H. pylori invade gastric mucosa?

Helicobacter pylori has been considered to be non-invasive and to rarely infiltrate the gastric mucosa, even though there is an active Th1 immune response in the lamina propria of the H. pylori-infected stomach.

What does the pyloric mucosa consist of?

The pyloric glands contain mucus-secreting cells. Several types of endocrine cells are found in throughout the gastric mucosa. The pyloric glands contain gastrin-producing cells (G cells); this hormone stimulates acid production from the parietal cells.

What is pyloric inflammation?

Helicobacter pylori (H. pylori) is a gram-negative bacterium that causes chronic inflammation (infection) in the stomach and duodenum and is a common contagious cause of ulcers worldwide. These bacteria are sometimes termed “ulcer bacteria.”

What does abnormal mucosa in the antrum mean?

Antrum mucosa erythematous defined means erythema, or redness, of the lining of the distal portion of the stomach. Antral mucosal erythema is commonly seen in patients with gastritis. Helicobacter pylori is a common cause for antral erythema, usually diagnosed with a biopsy taken during an endoscopy.

What toxins Does H. pylori release?

At the epithelial cell level H. pylori enzymes generate toxic molecules: ammonia (urease), lysolecithin (phospholipases) and acetaldehyde (alcohol dehydrogenase). The harmful effects of ammonia have been studied the most intensively and seem to be a likely mechanism of pathogenicity.

What are the symptoms of pyloric stenosis in adults?

Conclusion: Adult Idiopathic hypertrophic pyloric stenosis (AIHPS) is a rare disease which is also underreported due to a difficulty in diagnosis. The most common symptoms of AIHPS are postprandial nausea, vomiting, early satiety, and epigastric pain as seen in our patient.
