Study Notes
Acute Abdominal Pain
- Abdominal pain is a common complaint in outpatient settings.
- Many causes, both acute and chronic, can be evaluated.
- Prompt, focused evaluation is needed for causes with high morbidity and mortality.
- Differentiating diagnosis requires understanding pathophysiology, clinical presentation, course, and initial management.
- Focused history, physical exam, and appropriate testing are crucial.
- Abdominal pain is a frequent complaint (over 13.5 million visits in 2002).
- Patients often present first to primary care physicians.
- Pain can be a benign symptom or a life-threatening condition.
- This review outlines a framework for diagnosis.
Abdominal Anatomy, Physiology, and Pathology
- Abdominal viscera is innervated with nociceptive afferents.
- Pain patterns include visceral, parietal, and referred pain.
- Visceral pain is typically dull and poorly localized.
- Parietal pain is sharp and well localized.
- Referred pain occurs when visceral afferents enter the spinal cord at the same level as somatic afferents.
- Understanding anatomy and innervation allows for differential diagnosis based on location and distribution.
History and Physical Examination
- Thorough history of the patient's condition is essential.
- Previous medical history, medications, and substance abuse history are key elements.
- Quality, location, onset, duration, intensity, radiating symptoms, precipitating and relieving factors are needed.
- Physical examination includes general observations, vital signs, abdominal inspection, palpation, and auscultation.
- Importance of focused physical examination.
- Important findings such as guarding, rebound tenderness, or abnormal organ enlargement should be noted.
Diagnostic Considerations
- Red Flags indicating possible serious conditions.
- History, physical exam, and/or lab and imaging tests are used.
- Plain abdominal radiographs are often initial imaging tests.
- Computed tomography (CT) is a sensitive and specific modality for evaluating abdominal pain.
- Ultrasound may be useful for evaluating hepatobiliary issues.
- CT, MRI, Doppler ultrasound, conventional CT may be used for specific conditions.
- Patients with suspected acute conditions should be evaluated rapidly by specialists.
- High-cost and unavailability of some diagnostic tools.
Specific Abdominal Conditions
- Cholecystitis: Inflammation of the gallbladder, often due to gallstones, causes right upper quadrant pain and tenderness.
- Cholangitis: Infection of the bile ducts, usually associated with gallstones, presents with fever, jaundice, and right upper quadrant pain.
- Acute Pancreatitis: Inflammation of the pancreas, often from gallstones or alcohol abuse, characterized by severe epigastric pain radiating to the back.
- Appendicitis: Inflammation of the appendix, frequently leading to right lower quadrant pain.
- Diverticulitis: Inflammation of diverticula (small pouches) in the colon, typically causing left lower quadrant pain.
- Ischemic Bowel Disease: Reduced blood flow to the intestines, leading to abdominal pain and potential necrosis or perforation.
- Peptic Ulcer Disease (PUD): Erosions in the lining of the stomach or duodenum, resulting in pain that can vary in severity.
- Abdominal Aortic Aneurysm (AAA): Localized swelling in the abdominal aorta, which can lead to rupture—a potentially life-threatening condition.
- Inflammatory Bowel Disease (IBD): Includes Crohn's disease and ulcerative colitis, both with the potential for acute complications such as toxic megacolon, severe inflammation, and perforation.
Special Populations
- Elderly patients, patients with compromised immune systems, pregnant individuals, and patients under the influence of substances warrant specific consideration in the diagnostic approach given potential differences and presentations of common conditions.
