Study Notes

Definition of "Acute Abdomen"

An acute abdomen refers to a sudden onset of abdominal pain that suggests a serious underlying condition requiring urgent assessment and intervention.
It often presents with accompanying symptoms such as nausea, vomiting, fever, and changes in bowel habits.

Common Causes of an Acute Abdomen

Inflammatory Conditions
- Appendicitis
- Diverticulitis
- Pancreatitis
- Cholecystitis
Obstruction
- Bowel obstruction (due to adhesions, tumors, hernias)
- Gallstone ileus
Perforation
- Peptic ulcer perforation
- Trauma-related perforation
Vascular Issues
- Mesenteric ischemia
- Aortic aneurysm rupture
Other
- Intestinal ischemia
- PID (Pelvic Inflammatory Disease)
- Peritonitis (bacterial, tuberculous)

Eliciting Salient Features in History

Pain Characteristics: Onset, location, duration, intensity, and nature (sharp, dull, crampy).
Associated Symptoms: Fever, vomiting, diarrhea, constipation, urinary symptoms.
Past Medical History: Previous abdominal surgeries, known gastrointestinal diseases, and medications.
Social History: Diet, alcohol use, travel history, and exposure to illnesses.
Family History: Genetic predispositions to gastrointestinal diseases.

Examination of an Acute Abdomen

General Inspection: Look for signs of distress, guarding, or rigidity.
Vital Signs: Assess for fever, tachycardia, and hypotension.
Abdominal Examination:
- Palpation: Tenderness, rebound tenderness, and masses.
- Percussion: Assess for tympany or dullness (fluid).
- Auscultation: Listen for bowel sounds (normal, decreased, absent).
Rectal Examination: Check for blood in stool or masses.

Differential Diagnosis

Gastrointestinal Causes: Appendicitis, perforated ulcer, pancreatitis, bowel obstruction.
Genitourinary Causes: Ovarian torsion, ectopic pregnancy, urinary tract infection.
Vascular Causes: Mesenteric ischemia, aortic dissection.
Others: Myocardial infarction, pneumonia (referred pain).

Best Investigations Based on History

Laboratory Tests:
- Complete blood count (CBC): Check for leukocytosis or anemia.
- Electrolytes and renal function tests.
- Liver function tests (LFTs) if hepatobiliary disease is suspected.
- Urinalysis for urinary issues.
Imaging Studies:
- Ultrasound: Useful for gallbladder and pelvic pathology.
- CT Scan: Detailed view for appendicitis, bowel obstruction, pancreatitis.
- X-ray: May show bowel obstruction or perforation.

Management Plan

Stabilization:
- Monitor vital signs and provide IV fluids.
- Pain management.
Specific Treatment:
- Surgical intervention for appendicitis, perforation, or significant obstruction.
- Antibiotics for suspected infections (e.g., peritonitis).
Post-Operative Care:
- Monitor for complications (infection, bleeding).
- Gradual return to diet as tolerated.
Follow-Up:
- Schedule follow-up appointments to monitor recovery and address any further complications.

Definition of "Acute Abdomen"

Sudden onset of abdominal pain indicating a serious underlying condition needing urgent assessment and intervention.
Symptoms often include nausea, vomiting, fever, and changes in bowel habits.

Common Causes of an Acute Abdomen

Inflammatory Conditions encompass appendicitis, diverticulitis, pancreatitis, and cholecystitis.
Obstruction may occur due to bowel obstruction (adhesions, tumors, hernias) or gallstone ileus.
Perforation can result from peptic ulcers or trauma.
Vascular Issues include mesenteric ischemia and aortic aneurysm rupture.
Other causes involve intestinal ischemia, pelvic inflammatory disease (PID), and peritonitis (bacterial or tuberculous).

Eliciting Salient Features in History

Pain Characteristics: Evaluate onset, location, duration, intensity, and nature (sharp, dull, crampy).
Associated Symptoms: Note occurrences of fever, vomiting, diarrhea, constipation, and urinary issues.
Past Medical History: Consider previous abdominal surgeries, gastrointestinal diseases, and medication use.
Social History: Assess diet, alcohol consumption, travel experiences, and exposure to illnesses.
Family History: Investigate genetic predispositions to gastrointestinal conditions.

Examination of an Acute Abdomen

General Inspection: Observe for signs of distress, guarding, or abdominal rigidity.
Vital Signs: Check for fever, tachycardia, and hypotension.
Abdominal Examination:
- Palpation: Look for tenderness, rebound tenderness, and masses.
- Percussion: Identify tympany or dullness to assess fluid presence.
- Auscultation: Evaluate bowel sounds (normal, decreased, absent).
Rectal Examination: Inspect for blood in stool or masses.

Differential Diagnosis

Gastrointestinal Causes: Include appendicitis, perforated ulcers, pancreatitis, and bowel obstruction.
Genitourinary Causes: Examine for ovarian torsion, ectopic pregnancy, and urinary tract infections.
Vascular Causes: Rule out mesenteric ischemia and aortic dissection.
Others: Consider myocardial infarction and pneumonia, which can present with referred pain.

Best Investigations Based on History

Laboratory Tests:
- Complete blood count (CBC) to check for leukocytosis or anemia.
- Electrolytes and renal function tests to assess overall health.
- Liver function tests (LFTs) for suspected hepatobiliary disease.
- Urinalysis for possible urinary issues.
Imaging Studies:
- Ultrasound: Effective for assessing gallbladder and pelvic pathology.
- CT Scan: Provides detailed images for appendicitis, bowel obstruction, and pancreatitis.
- X-ray: Useful for detecting bowel obstruction or perforation.

Management Plan

Stabilization: Monitor vital signs, provide IV fluids, and manage pain effectively.
Specific Treatment: May require surgical intervention for appendicitis, perforation, or significant obstruction; antibiotics for suspected infections like peritonitis.
Post-Operative Care: Monitor for potential complications such as infection or bleeding; gradually return to diet as tolerated.
Follow-Up: Schedule appointments to assess recovery and manage any further complications.
