Clinical-Stomach Disorders Flashcards
What is Portal hypertension gastropathy
Congestion of the capillaries and venules of the gastric mucosal and submucosal layers
What can be given in the case of portal hypertensive gastropathy to reduce recurrent bleeding
Propranolol or nadolol
What is the most common clinical manifestation of erosive gastritis
Upper GI bleeding, resulting in hematemesis, “coffee ground” emesis, or bloody aspirate during nasogastric suction
*Usually not hemodynamically significant bleeding
During hemorrhagic gastritis, what is the method of diagnosis and what is the state of inflammation
Upper endoscopy, which will not show significant inflammation on histology
What is the location of Type A gastritis
Body predominant
In Type A gastritis, what are the autoimmune mechanisms associated with
- achlorhydria
- pernicious anemia
- gastric cancer risk
What antibodies are present in the majority of type A gastritis
Antibodies to parietal cells
What is the process of Achlorhydria
- Hypergastrinemia due to loss of regulation on G cells
- Hyperplasia of ECF cells (due to increased gastrin)
What can achlorydia lead to
Small multi centric carcinoid tumors
What population is more common for pernicious anemia gastritis
Females
What are the effects of pernicious anemia gastritis
- Megablastic anemia (due to decrease IF secretion and B12 absorption)
- Autoimmune destruction of gastric fundic mucosa
- Increased risk for gastric adenocarcinoma
What is the cause of Type A gastritis
Rare autoimmune disorder involving the fundic glands
What is the location and cause of type B gastritis
Antral dominated infection with H. Pylori
H pylori is associated with an increased risk of which condition
Gastric cancer
What is the characteristic morphology associated with Menetrier disease
Giant thickened gastric folds in the body of the stomach
What are the symptoms of Menetrier disease
-Chronic protein loss, leading to anasarca (general swelling throughout the body)
Where does peptic ulcer disease most commonly occur
Duodenal bulb and stomach
What are the typical descriptions given by the patient for peptic ulcer disease
- gnawing
- dull
- aching
- “hunger like”
What are the signs of peptic ulcer bleeding
“Coffee grounds” emesis
- hematemesis
- melena
- hematochezia
What is the rule of thumb for exclusion of nasogastric lavage fluid without blood with regards to active bleeding of a duodenal ulcer
Does not rule it out
What is the prevalence of H pylori in duodenal bleeds, and what is the cause
70-90% and due to increased gastric acid secretion
What is the prevalence of H. Pylori in gastric ulcers and what is the cause
Infection of the gastric body decreased acid secretion
