Strategic clinical approach to surgical emergencies for International Medical Graduates.
The MCCQE frequently tests the initial assessment and stabilization of patients presenting with acute abdominal pain. A systematic approach focusing on the "surgical sieve" and anatomical quadrants is essential for narrowing the differential diagnosis.
Biliary pathology is the most common cause of RUQ pain. Distinguishing between biliary colic, cholecystitis, and cholangitis is a frequent exam objective. Ultrasound remains the gold-standard initial investigation for RUQ pain in Canada.
Appendicitis is the "classic" surgical emergency. In the MCCQE, pay close attention to the Alvarado score and the use of CT imaging (with IV contrast) for confirmation in adults, while ultrasound is preferred in children and pregnant women to minimize radiation.
Management of the acute abdomen begins with the "ABCs" of resuscitation. For surgical candidates, pre-operative optimization is key. This includes fluid resuscitation, electrolyte correction, and, where indicated, the administration of broad-spectrum antibiotics.
The "5 Ws" of post-operative fever are a staple of Canadian medical exams. Identifying the timing of the fever is crucial for determining the likely cause:
