[Section Outline]

Signs and Symptoms!!navigator!!

History

  • NSAID, aspirin
  • Smoking
  • Previous history of PUD
  • Family history of stomach cancer
  • Abdominal pain
  • Diarrhea
  • Weakness

Physical Exam

  • Abdominal tenderness
  • Signs of anemia
  • Guaiac-positive stool

Essential Workup!!navigator!!

Diagnostic Tests & Interpretation!!navigator!!

Lab

  • Normal lab values in uncomplicated ulcer disease
  • CBC:
    • Low hematocrit with bleeding
    • Leukocytosis with perforation/penetration
  • Amylase/lipase:
    • Elevated with perforation/penetration
    • Pancreatitis is in differential diagnosis
  • Electrolytes, BUN/creatinine, glucose for critically ill
  • Type and cross-match for significant blood loss
  • H. pylori testing (urea breath test, H. pylori antibodies, IgG)

Imaging

  • CXR abdominal series:
    • Evaluate for perforations/obstructions

Diagnostic Procedures/Surgery

  • ECG:
    • For elderly patients
    • Myocardial ischemia is in differential diagnosis
  • Endoscopy:
    • Procedure of choice
    • Outpatient unless significant hemorrhage
    • Allows for biopsies of gastric/duodenal ulcers for presence of H. pylori
    • Detects malignant gastric ulcers
  • Upper GI series:
    • Single contrast barium diagnoses 70-80%
    • Double contrast diagnoses 90%
  • Gastrin level is elevated in Zollinger-Ellison syndrome

Admission Criteria

  • Gastric obstruction
  • Perforation
  • Active upper GI bleed
  • Melena
  • Uncontrolled pain
  • Anemia requiring transfusion

Discharge Criteria

  • Unremarkable physical exam with normal CBC and heme-negative stools
  • If heme-positive stools, discharge if stable vital signs, normal hematocrit, and negative NGT aspiration for upper GI hemorrhage

Issues for Referral

Outpatient GI evaluation and endoscopy

Follow-up Recommendations!!navigator!!

Pearls and Pitfalls

  • H. pylori infection is the most common cause of PUD
  • NSAID-induced PUD is frequently silent
  • Dyspeptic symptoms are nonspecific
  • Endoscopy is diagnostic and should include H. pylori screening
  • Treatment should include H. pylori eradication and H2 blockers or PPIs
  • Complications include perforations, hemorrhage, anemia
  • Failure to follow up may result in failure to diagnose gastric cancer
