  1. Nonsteroidal Antiinflammatory Drugs (NSAIDs)
    1. Peptic ulcers occur in 5-20% of longterm NSAID use
  2. Helicobacter Pylori
    1. Duodenal Ulcer: 90-100% Prevalence

  3. Acid Induced Ulcers
    1. Idiopathic
    2. Zollinger-Ellison Syndrome

    7. Chronic Renal Failure
    8. Cirrhosis
  • Risk Factors
  • Symptoms
  1. Duodenal Ulcer
    1. Mid-Epigastric Pain, deep recurring ache
    2. Relieved with food or Antacids
    3. Aggravated by general irritants (below)
    4. Nocturnal pain is present
  2. Gastric Ulcer
    1. Mid-Epigastric Pain
    2. Relieved by Antacids
    3. Aggravated by food and general irritants (below)
    4. Constitutional symptoms
      1. Anorexia
      2. Weight loss
      3. Nausea or Vomiting
  • Red Flags
  • Presentations
  • Special cohorts
  1. Children (rare): Presents with poorly localized Abdominal Pain
  2. Elderly
    1. Presents asymptomatically or non-specifically (e.g. confusion, Abdominal Distention)
    2. High risk of perforation and mortality
  3. Stress Ulcers
    1. Presents in seriously ill hospitalized patients (Mechanical Ventilation, Burn Injury)
  4. Pregnancy
    1. See Dyspepsia in Pregnancy
  • Differential Diagnosis
  1. See Dyspepsia Causes
  2. See Medication Causes of Dyspepsia
  3. Most common misdiagnoses for Peptic Ulcer Disease
    1. Functional Dyspepsia
    2. Esophagitis
    3. Gastroesophageal Reflux
    4. Gastritis
    5. Gastroenteritis
  4. Less common misdiagnoses for Peptic Ulcer Disease
    1. Biliary tract disease (Cholecystitis, Cholelithiasis, Ascending Cholangitis)
    2. Celiac Sprue (Gluten Sensitive Enteropathy)
    3. Inflammatory Bowel Disease
    4. Irritable Bowel Syndrome
    5. Pancreatitis
    6. Appendicitis
  5. Uncommon misdiagnoses for Peptic Ulcer Disease

    2. Acute Coronary Syndrome
    3. Barrett Esophagus
    4. Gastric Cancer
    5. Ischemic bowel disease in the elderly
    6. Viral Hepatitis
    7. Zollinger-Ellison Syndrome
  • Diagnostics
  1. See Dyspepsia for evaluation protocol
  2. No additional investigation necessary if
    1. Symptoms consistent with Duodenal Ulcer and
    2. Medication leads to healing within 6 weeks
  3. Upper Endoscopy Indications
    1. Assess and reassess Gastric Ulcers
    2. Evaluate for Gastric Carcinoma in high risk groups
      1. See Dyspepsia Red Flags
  4. Upper GI with Follow Through
    1. May be sufficient for Duodenal Ulcers
  5. Helicobacter Pylori testing if ulcer not NSAID related
    1. See Helicobacter pylori Noninvasive Testing
  • Management
  • General Measures
  1. Avoid Gastric Irritants
  2. Avoid bland diets (not effective)
    1. May stimulate greater acid production
  • Management
  • Cause specific
  • Management
  • Refractory Peptic Ulcer
  1. Causes
    1. Persistent NSAID use
    2. Resistant Helicobacter Pylori infection
    3. Gastric Cancer
    4. Zollinger-Ellison Syndrome
  2. Measures
    1. Continue Proton Pump Inhibitors
    2. Consider surgical intervention in severe cases or those at high risk of complications
      1. Duodenal Ulcer: Vagotomy or Partial Gastrectomy
      2. Gastric Ulcer: Partial Gastrectomy
  • Prevention
  1. Avoid NSAIDs
    1. See NSAID Gastrointestinal Adverse Effects for risks (and prophylaxis options if NSAIDS are needed)
  • Prognosis
  1. Proton Pump Inhibitors have higher efficacy than H2 Antagonists
  2. On Proton Pump Inhibitor
    1. Duodenal Ulcers heal in 95% of cases within 4 week
    2. Gastric Ulcers heal in 80-90% of cases within 8 weeks
  3. Recurrence risk (Duodenal Ulcers)
    1. Non-smoker recurrence in 1 year: 60%
    2. Smoker recurrence in 1 year: >75%
  • Complications
  1. Complications occur in 25% of cases (especially in Elderly taking NSAIDs)
  2. Gastrointestinal Hemorrhage (15-20% of cases)
    1. See Upper Gastrointestinal Bleeding
  3. Gastrointestinal Perforation
    1. Incidence: 1 per 10,000 per year for non-NSAID related peptic ulcer perforation
    2. Presents with severe Abdominal Pain, Acute Abdomen, with regional inflammation (Pancreatitis, hepatitis)
    3. Lowest mortality (6-14%) is associated with the earliest management in younger patients without comorbidity
  4. Gastric Outlet Obstruction (rare)
    1. Duodenum narrows with recurrent or persistent ulceration and secondary inflammation and scarring
    2. Presents with Retching and hematemsis
    3. Evaluate differential diagnosis including cancer
