- Relieves with defecation
- no weight loss or bleeding
Duodenal ulcers caused pain how long after meals? Relieved by?
2 to 5 hours after a meal. Food or antacids.
If food worsens gastric pain - think?
Gastric ulcer
Gastric cancer can present with dysphasia if? Persistent vomiting if? Early satiety it?
In the cardiac region of the stomach. Blocking the pyloric channel. Mass effect or infiltration of the stomach wall.
When should patients undergo endoscopy for dyspepsia?
- Older than 45 years who present with new onset dyspepsia
- Patients with alarm symptoms (weight-loss, recurrent vomiting, dysphasia, bleeding, anemia)
- Symptoms have failed to respond to empiric therapy
In younger patients with no alarm features - strategy for dyspepsia?
Urea breath test or H. pylori antibody test
Problem with H. pylori antibody test?
Will remain positive for life even after successful treatment
Cancers associated with H. pylori?
Gastric carcinoma and gastric MALT lymphoma
Treatment for H. pylori?
Clarithromycin, amoxicillin and a PPI
Major cause of duodenal and gastric ulcers not caused by H. pylori? Mech?
NSAIDs. Inhibit prostaglandin synthesis resulting in reduced secretion of mucus and bicarb and decreased mucosal bloodflow

Zollinger-Ellison syndrome. Serum gastrin levels greater than 1000
Free perforation into the abdominal cavity may cause?

#Alcohol #NSAIDs #H pylori #Portal hypertension #Stress (trauma, burns, sepsis, uremia)

B12
Test to diagnose erosive gastritis?
#Endoscopy to diagnose #H pylori testing
H pylori testing options?
#endoscopic biopsy – most accurate/invasive #Serology – negative test excludes infection but lacks specificity (current versus old infection?) #Urea breath testing – positive only in activity fiction # stool antigen – positive only in active infection
When to give stress ulcer prophylaxis?
#Mechanical ventilation #head trauma #burns #Coagulopathy
Role of alcohol and tobacco in PUD?
Delay healing of ulcers (do not cause ulcers)
