  • Dysphagia.
  • Regurgitation.
  • Radiologic evidence of distal esophageal narrowing.
  • Absence of esophageal peristalsis on esophageal manometry.

H. pylori

6

What is the tx for H. pylori infection?

14 days of

MOC = metronidazole, omeprazole, clarithromycin

or

ACO = ampicillin, clarithromycin, omeprazole

O - obstruction (gastric outlet obstruction)

P - perforation

12

What is the purpose of the Ranson criteria?

predict mortality after pancreatitis

13

What are the elements of the Ranson criteria and how is the score interpreted?

 

Criteria present at 0 hours:

  • Age >55 years old (1 point)
  • WBC >16,000/mm(3) (1 point)
  • Glucose >200 mg/dL (1 point)
  • LDH >350 U/L (1 point)
  • AST >250 U/L (1 point)

Criteria present at 48 hours:

  • Hematocrit fall of 10% or greater (1 point)
  • BUN rise of 5 mg/dL or more despite fluids (1 point)
  • Serum Calcium <8 mg/dL (1 point)
  • pO2 <60 mmHg (1 point)
  • Base deficit >4 meq/L (1 point)
  • Fluid sequestration >6000 mL (1 point)

Interpretation:

0-2 Points: Mortality 0-3 percent
3-5 Points: Mortality 11-15 percent
6-11 Points: Mortality >=40 percent
