Small Animal Surgery
Core concepts
The small animal candidate must move fluidly between wound management, gastrointestinal and hepatobiliary surgery, urogenital procedures, orthopedic stabilization, and perioperative physiology. Know the phases of wound healing (hemostasis, inflammation, proliferation, remodeling), the difference between primary, delayed primary, and second-intention closure, and when to debride versus drain. Understand tension lines, blood supply of skin flaps, and the rationale for open wound management in contaminated fields.
Traps to expect
Questions love the 'most appropriate next step' phrasing. Distinguish stabilization from definitive repair: a blocked cat or a GDV needs resuscitation before anesthesia. Watch for distractors that confuse species-specific anatomy (e.g., feline urethra, canine biliary anatomy). Orthopedic questions often hinge on recognizing Salter-Harris classification or the difference between stable and unstable fractures. Antibiotic timing (within 60 minutes of incision for clean-contaminated procedures) is a frequent discriminator.
Worked example
A dog presents with a 3-day-old contaminated bite wound over the flank. The trap answer is 'primary closure after lavage.' The correct reasoning: contaminated, devitalized tissue requires surgical debridement, lavage, and open or delayed primary closure once granulation is established. Rule of thumb: never close a wound you cannot confidently debride to healthy bleeding tissue.
Exam strategy
Anchor each answer to the physiologic principle (perfusion, contamination, tension) rather than memorized protocols. Read the stem for stability cues and comorbidities that change the plan.
