  • 22. The differential is broad . A good H&P is crucial.
  • 23. Table 36-2 Emergency Medicine: A Comprehensive Study Guide, 6th ed. Most Common Causes of Acute Abdominal Pain Final Diagnosis Proportion Nonspecific abdominal pain (NSAP) 34% Appendicitis 28% Biliary tract disease 10% Acute gynecologic disease 4%    Salpingitis 68%    Ovarian cyst 21%    Ectopic 6%    Incomplete abortion 5% Small bowel obstruction 4% (2% if <50yo) Pancreatitis 3% Renal colic 3% Perforated peptic ulcer 3% Cancer 2% Diverticular disease 2% Other (<1% each) 6%
  • 24. Patient Management Recommendations: Evaluating Abdominal Pain (ACEP Clinical Policies) Guidelines. 1. Do not restrict the differential diagnosis solely by the location of the pain. 2. Do not use the presence or absence of a fever to distinguish surgical from medical etiologies of abdominal pain. Options. 1. Use serial evaluations over several hours to improve the diagnostic accuracy in patients with unclear causes of abdominal pain. 2. Collect a complete data set before reaching a differential diagnosis; consider a systemic data collection tool, such as a formatted chart. 3. Perform a stool for occult blood test in patients with abdominal pain. 4. Perform a pelvic examination in female patients with abdominal pain.
