Surgery and Allied Specialties
What you must understand
Surgical questions test safe decision-making more than operative detail. Know the assessment of the acute abdomen, the differentiation of obstruction from ileus, the features of peritonitis and perforation, and the indications for immediate laparotomy. Understand shock - its types, the clinical signs that separate them, and the principles of damage-control resuscitation. Learn the classification and initial management of burns, the management of trauma along the primary survey (airway with cervical spine control, breathing, circulation, disability, exposure), and the signs of compartment syndrome and tension pneumothorax, both of which are clinical diagnoses requiring immediate action.
In general surgery, master the hernia types and their complications, the differential of a breast lump by age, the evaluation of thyroid swelling, the staging logic of colorectal and gastric cancer, and the principles of wound healing and surgical site infection. In urology, know the management of acute urinary retention, renal colic, and testicular torsion - the last being a surgical emergency where imaging must not delay exploration.
Traps that appear
Questions frequently present a stable-looking patient with a time-critical diagnosis. Tension pneumothorax, testicular torsion, necrotising fasciitis, and closed-loop obstruction all demand action rather than investigation. Distinguish strangulation from obstruction, and incisional from inguinal hernia. Beware of answers that describe an investigation when the question asks for immediate management.
Worked rule of thumb
For any acute surgical vignette, apply the two-minute rule: airway, breathing, circulation, then the single most likely diagnosis, then the immediate action. If the answer options include both an investigation and a definitive intervention, and the patient is unstable or the diagnosis is time-critical, choose the intervention.
Study strategy
Rehearse the primary survey aloud until it is automatic, and pair each common emergency with its single decisive management step.
