Pyloric Obstruction01:11

Pyloric Obstruction

34
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Gastritis II: Pathophysiology

43
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...

Gastritis-II: Pathophysiology

1.9K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Gastritis-I: Introduction and Types

3.7K
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Hormones Secreted by the Stomach

2.9K
Enteroendocrine cells, accounting for only 1% of stomach epithelial cells, play a significant role in digestion and are classified by their digestive hormone secretions.
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Oncology

Background:

  • Glomus tumors (GTs) are typically benign neoplasms arising from glomus cells.
  • They commonly occur in distal extremities, rarely involving visceral organs.
  • Gastric GTs present unique diagnostic and management challenges.

Observation:

  • A patient presented with exsanguinating hematemesis and severe anemia due to a rare gastric glomus tumor.
  • Initial diagnostic tests were inconclusive, necessitating further investigation.
  • Contrast-enhanced computed tomography identified a duodenal soft tissue density lesion.

Findings:

  • A 3 × 2.5 × 2 cm mass was surgically located at the pylorus.
  • Histopathology confirmed the diagnosis of a glomus tumor.
  • Immunohistochemistry showed smooth muscle actin and focal CD34 expression.

Implications:

  • This case underscores the importance of considering rare diagnoses in unexplained gastrointestinal bleeding.
  • Surgical intervention is crucial for diagnosis and treatment of symptomatic gastric GTs.
  • Further research into the molecular characteristics of visceral GTs may improve diagnostic accuracy.
