Stomach Flashcards
(31 cards)
Most all non-NSAID induced gastritis caused by
H. pylori
Type A gastritis
Autoimmune - pernicious anemia
Involves the BODY of the stomach
Type B gastritis
H. pylori, involves the ANTRUM and BODY of stomach
H. pylori also associated w
PUD
Gastric Adenocarcinoma
Gastric Lymphoma
Diminishes local prostaglandin production in the stomach or duodenum
NSAIDs
Non NSAID, non H. Pyori gastriti
ALCOHOL
Diagnostic studies for gastritis
Endoscopy - biopsy, location/extent of gastritis, presence of H. pylori
Non invasive diagnostic study for H. pylori
Urea breath test
Fecal antigen testing
Any ulcer of the upper GI system (gastric, duodenal)
PUD
Most common cause of PUD
H. pylori
Lifetime risk of ulcer disease
5-10%
Equal for men and women
DDX for PUD
Dyspepsia Abdominal pain Nausea can also be associated with
Gastritis
Malignancy
Ischemic Heart Disease
How does bleeding w PUD typically manifest
Melena
Most common cause of nonhemorrhagic GI bleeds
PUD
Combo therapy for H. pylori
2-4 weeks
1) PPI with clarithromycin and amoxacillin OR clarithromycin with metronidazole
2) Bismuth salicylate with tetracycline, metranidazole, and PPI
Tx for patients with history of ulcer who require daily NSAID use, or a need for chronic steroids
Prophylactic treatment with
Misoprostol or PPI
Gastrin-secreting tumor, results in refractory PUD
Zollinger Ellison Syndrome
Percentage of PUD caused by ZES
1%
About 1/3 of gastrinomas are part of an autosomal dominant condition syndrome
Multiple Endocrine Neoplasm type I
Clinical feature of ZES that is different from PUD
More refractory
May present with secretory diarrhea that improves w H2 blockers or PPIs
Diagnosis of hypergastrinemia
Fasting gastrin level > 150ph/mL
Test needed to confirm presences of ZES
Secretin test
differentiates patients with Gastrinomas and peptic ulcer disease, even in the presence of acid blockers
ZES positive patients, gastrin levels will subsequently increase by > 200pg/mL
Signs of metastatic spread of gastric adenocarcinoma
Virchow’s node - Left Supraclavivular Lymphadenopathy
Sister Mary Joseph Nodule (umbilical nodule)
The presence of an umbilical nodule (Sister Mary Joseph nodule) and/or Virchow’s node (Left supraclavicular lymphadenopathy) indicates what
Metastasized gastric adenocarcinoma
