Surgery – MCCQE1 High-Yield Notes

Surgery questions in the MCCQE1 focus on diagnosis and initial management of acute surgical conditions, trauma assessment, and recognizing post-operative complications.

🔑 Key Topics for MCCQE1

Acute abdomen approach: history, physical, investigations (CBC, lipase, imaging)
Appendicitis: RLQ pain, Alvarado score, CT confirmation, laparoscopic appendectomy
Bowel obstruction: SBO vs LBO, causes, X-ray findings, NG tube decompression
Acute cholecystitis: RUQ pain, Murphy sign, ultrasound, laparoscopic cholecystectomy
Pancreatitis: Ranson criteria, CT severity index, supportive management
Peptic ulcer disease: H. pylori testing/treatment, PPI, surgical indications
GI bleeding: upper vs lower, hemodynamic stabilization, endoscopy
Trauma (ATLS): primary survey ABCDE, massive transfusion protocol
Tension pneumothorax: clinical diagnosis, immediate needle decompression
Abdominal aortic aneurysm: >5.5 cm or symptomatic → surgical repair
Hernias: inguinal (direct vs indirect), femoral, incisional – strangulation signs
Thyroid nodule: FNA, Bethesda classification, indications for surgery
Breast lump: triple assessment (clinical + imaging + biopsy), sentinel node biopsy
Post-op fever 5 Ws: Wind (1-2d), Water (3d), Wound (5-7d), Walking (DVT), Wonder drugs
Pre-operative assessment: cardiac risk (RCRI), pulmonary optimization, medication management

⚠️ High-Yield Clinical Pearls

Appendicitis: Rovsing sign, psoas sign – if perforated → broad-spectrum antibiotics first
Tension pneumothorax: Do NOT wait for X-ray – needle decompression 2nd ICS MCL immediately
Bowel obstruction: Closed-loop = surgical emergency (risk of strangulation)
Pancreatitis: NPO + aggressive IV fluids + pain control (morphine is fine)
AAA screening: Ultrasound for men aged 65–75 who ever smoked (one-time screen)
Post-op fever day 1-2: Atelectasis (Wind) → incentive spirometry, ambulation

📊 Quick Reference Table

Condition	Key Investigation	Management
Appendicitis	CT abdomen/pelvis	Laparoscopic appendectomy
Cholecystitis	Ultrasound RUQ	Lap cholecystectomy (early)
Pancreatitis	Lipase >3x normal	IV fluids, NPO, analgesia
Tension PTX	Clinical diagnosis	Needle decompression NOW
Upper GI bleed	Endoscopy	PPI IV + endoscopic hemostasis
