Peptic ulcer disease

Background

• Recurrent ulcerations in the stomach and proximal duodenum
• Majority of cases related to H. pylori or NSAID use
  • H. pylori found in 30-40% of U.S. population
  • NSAIDs inhibit prostaglandin synthesis (decreases mucus and bicarb production)

Diagnosis

• Burning epigastric pain
  • May awaken pt at night (gastric contents empty)
• Abrupt onset of severe pain may indicate perforation
• Abrupt onset of back pain may indicate penetration into the pancreas
• The following symptoms are NOT associated w/ PUD:
  • Postprandial pain, food intolerance, nausea, retrosternal pain, belching

Work-Up

• CBC (r/o anemia)
• LFTs
• Lipase
• ?Acute abd series
• ?RUQ US
• ?ECG
• ?Troponin

Differential Diagnosis

Epigastric Pain

• Gastroesophageal reflux disease (GERD)
• Peptic ulcer disease with or without perforation
  • Zollinger-Ellison syndrome
• Gastritis
• Pancreatitis
• Gallbladder disease
  • Acute cholecystitis
  • Cholangitis
  • Symptomatic cholelithiasis
  • Acalculous cholecystitis
• Myocardial Ischemia
• Splenic Infarctionenlargement/rupture/aneurysm
• Pericarditis/Myocarditis
• Aortic dissection
• Hepatitis
• Pyelonephritis
• Pneumonia
• Pyogenic liver abscess
• Fitz-Hugh-Curtis Syndrome
• Hepatomegaly due to CHF
• Bowel obstruction
• SMA syndrome
• Pulmonary embolism
• Bezoar
• Ingested foreign body

Treatment

• Stop NSAIDs and Etoh
• Eradicate H. pylori if identified in symptomatic pt
  • Triple Therapy: PPI + clarithromycin 500mg BID + (amoxicillin 1g or metronidazole 500mg) BID x 10-14d
  • Quadruple Therapy: PPI + bismuth subsalicylate 524 mg QID + metronidazole 250 mg QID and tetracycline 500 mg QID x 10-14d
• PPI
  • Generally heal ulcers faster than H2 blockers
  • Omeprazole 20-40mg QD
• H2 Blockers
  • Famotidine 20-40mg QD
  • Ranitidine 75-150mg BID

Disposition

• Normally outpatient management, unless complication (see below)

Red Flags

Any of the following suggest need for endoscopy referral:

• Age >55yr
• Unexplained weight loss
• Early satiety
• Persistent vomiting
• Dysphagia
• Anemia or GI bleeding
• Abdominal mass
• Persistent anorexia
• Jaundice

Complications

• Hemorrhage
  • Upper GI Bleeding
• Perforation
  • Most commonly occurs in anterior wall of duodenum.
  • Abrupt onset of severe epigastric pain
  • Pts may not have history of ulcer-like sx
  • Consult surgery
• Obstruction
  • Occurs due to:
    • Scarring of gastric outlet
    • Edema due to active ulcer
