Peptic ulcer disease and gastritis Flashcards
Define Peptic ulcer disease and gastritis
peptic ulcer-5mm break in lining of stomach or duodenum, depth through the mucosa, not submucosa
Gastritis-inflammation of the stomach lining, often because of H pylori/NSAIDS. Erosive gastritis-smaller ulcers, not big enough to be considered ulcer. Non erosive-chronic
Aetiology and risk factors of Peptic ulcer disease and gastritis
The most common causes for all of these are-H.pylori infections and NSAID
rare causes include stress
usually due to imbalance between acid production and mucosal lining protection
H.pylori cause hypersecretion (by decreasing somatostatin/gastrin) of acid in duodenum which causes ulcer
but causes reducing of mucosa (and normal acid) in gastric ulcers
NSAID’s cause damage directly by trapping H ions and reducing COX enzymes-decrease lining
Autoimmune gastritis exists-damage to parietal cells
GASTRITIS often seen as stage before ulcers
Risk factors: Chronic use of NSAIDs H.pylori Smoking Age gastric-60-70, duodenal-40-50 Previous Hx of ulcers
Epidiemology of Peptic ulcer disease and gastritis
Ulcers are very common-main cause of dyspepsia in UK by far
Duodenal ulcers are much more common than gastric (80%-20%)
HPylori on the decline, and NSAID related on the rise, in the west
Signs and Sx of Peptic ulcer disease and gastritis
Duodenal-Dyspepsia especially AFTER meals, better during
Gastric-dyspepsia during meals, better after
Gastritis-dyspepsia worse with meals
always centre of epigastric
can have nausea and vom, better when eating
NO SIGNS OF MALIGNANCY
bad-upper gi bleed
can have Sx of aneamia as the ulcer bleed
Malena
Investigations of Peptic ulcer disease and gastritis
FBC-aneamia (if older patient-OGD needed)
PPI trial therapy-if responds most likely
If significant bleed-OGD
OGD is gold standard diagnostic
Urea breath test
H.pylori stool test (need to stop PPI 2 weeks before those)-so care not to do trial PPI first
Management of Peptic ulcer disease and gastritis
NSAID ulcers/gastritis-if Pylori negative-add PPI to NSAID, or stop NSAID if not getting better
2nd line H2 antagonist (famotidine)
H.pylori related Triple therapy PPI BD (normally OD) Amoxicillin then either clarythromycin or metronidazole
Complications of Peptic ulcer disease and gastritis
Ulcers-bleeds-chronic aneamia
Chronic-penetration-can go full depth and leak into other organ (pancreas)-might need surgery
Perforation-penetrate into peritoneum-shock and peritonitis
Gastric stenosis-Obstruction
Upper GI bleeds-life threatening
gastric cancer-H.pylori is main risk factor of adenocarcinoma
gastritis risks ulcers
Prognosis of Peptic ulcer disease and gastritis
With triple therapy -Ulcers heal within 4-8 weeks usually
but recurrence can be 20%
NSAID related-stopping the NSAID always does the trick
Erosive and Pylori gastritis also have good prognosis
