Peptic ulcer & aspirin Flashcards
Peptic ulcer?
It is mucosal defect in the portion of gastrointestinal tract exposed to acid and pepsin secretion
What increases the risk?
Infection with H pylori
Use of aspirin and NSAIDS
Minor factors: use of warfarin & corticosteroids
Complications?
Penetration - gastro content erodes to adjacent organs like liver and pancreas
Perforation - gastro content enter the peritoneum, causing peritonitis
Hemorrhage - bleeding with vomiting and black faeces
Pathophysio?
imbalance of aggresive and defensive factors
Diagnosis
Not easy to differentiate PUD and gastriris based on symptoms.
Differentiate = endoscopy and contrast radiography
Diagnose H pylori= gastric mucosal biopsy culture, 13c urea breath test, ELIDA test on H pylori immunoglobulins
Causes of gastritis & PUD
H pylori - it moves deep into the mucosal gel which coats the gastric mucosa and hence disrupt its function
NSAIDS, aspirin - inhibit mucosal enzyme, cyclooxygenase, hence reducing mucosal PGE, cannot produce mucus
Gastrinoma - gastrin secretion tumor, secretes gastrin till ulceration occurs
Alcohol
Severe Stress
Symptoms of PUD
Pain in the upper abdomen
Pain usually occurs when stomach is empty
Gastric ulcer - sharp pain in the stomach after eating
Duodenal ulcer - pain relieved by eating
Nausea & vomiting (green/bloody)
Bloating
Severe = vomiting large amt of blood, rapid bleeding in stomach, feeling of faint
Treatment of PUD
Endoscopy used to see the ulceration area and obtain a biopsy
Neutralize acid by antacid
Decrease acid production by using H2 receptor antagonist or proton pump inhibitor
