Disturbance in Digestion Flashcards
Gastritis
inflammation of the gastric/stomach mucosa
- older adults
Gastritis
Acute Gastritis
- several hours - few days
- → gangrenous/perforate mucosa → scarring → obstruction/pyloric stenosis
- more severe form form is caused by ingestion of strong acid/alkali
- → severe illness
Acute Gastritis (Gastritis)
Erosive
caused by:
* local irritants (aspirin, NSAIDs)
* gastric radiation therapy
Acute Gastritis (Gastritis)
Nonerosive
caused by H. pylori infection
Gastritis
Chronic Gastritis
- repeated exposure
- most often from H. pylori infection
- in devt. of PU, gastric cancer, gastric mucosa-associated lymphoid tissue lymphoma
- caused by gastropathy
- w/ Hashimoto thyroiditis, Addison d., Grave’s d.
Gastritis
Pathophysiology
mucosal barrier → disrupted/damaged → irritants (gastric juices) → inflammation

PUD (Treatment)
Billroth I
creation of anastomosis bet. duodenum and gastric remnants
gastroduodenostomy
feeling of fullness and dumping syndrome
PUD (Treatment)
Billroth II
sewing a loop of jejunum to the gastric remnant
gastrojejunostomy
dumping syndrome, anemia, wieght loss
