Workup

Labs

• Abdominal panel
  • CBC
  • Chemistry
  • LFTs + lipase
  • Coagulation studies (PT, PTT, INR), as a marker of liver function
• Urinalysis
  • Leukocytes will be present in 40% of patients
  • Urine pregnancy test (if age and sex appropriate)

Imaging

• Biliary ultrasound
• Consider CXR to assess for free air under the diaphram
  • If at risk for a perforated ulcer (e.g., age >55)
• Consider ECG
  • If may be cardiac in nature

Management
