Iran General Surgery Board Exam common mistakes
Iran General Surgery Board Exam · Understand the traps and how to avoid them.
When asked to choose the next step in a trauma scenario, candidates jump straight to CT scanning or definitive operative repair instead of first completing the primary survey and stating the resuscitation endpoint (e.g., responding to 1–2 L crystalloid or blood, transient responder, non-responder).
Exam stems are long and the dramatic injury (ruptured spleen, widened mediastinum) dominates attention; candidates recall the definitive management from textbooks and skip the ABCDE/decision-node step the question is actually testing.
What to do instead
Before answering any trauma item, write one line: 'Primary survey done? Hemodynamic class? Responder status?' Then select the option that matches that node. Practise 30 stems where the correct answer is 'continue resuscitation and reassess' rather than 'operate'.
In shock and burn questions, candidates calculate fluid volumes with the wrong formula or wrong weight/timing (e.g., using the Parkland formula total as the hourly rate, or forgetting that the first 8 hours are counted from the time of injury, not from arrival).
Multiple formulas (Parkland, Brooke, maintenance 4-2-1, ATLS classes) are memorized as isolated numbers without a mental model of what each one estimates.
What to do instead
Build a one-page formula sheet and always annotate units, denominator (per %TBSA, per kg), and clock start. Answer 20 burn/shock calculations aloud, stating 'half in first 8 h from injury' each time.
Candidates answer perioperative risk questions using gestalt ('looks high risk') instead of naming and applying a specific validated tool and its thresholds - ASA class, Revised Cardiac Risk Index, Caprini, or NSQIP risk calculator - and cannot state which patients need preoperative cardiac stress testing versus proceeding.
Risk assessment is learned on the ward by imitation rather than by explicit criteria, and guidelines on when testing changes management are rarely read in full.
What to do instead
Memorize the RCRI variables and the rule that testing is indicated only when it will change management; memorize Caprini cut-offs for chemoprophylaxis. For each of 15 vignettes, write the score and the resulting action before looking at options.
On hernia and abdominal wall items, candidates classify by appearance rather than by the anatomic defect and its relation to the inguinal ligament and inferior epigastric vessels, and they confuse direct/indirect/pantaloon and femoral hernias when the stem describes an emergency presentation.
Inguinal anatomy is studied as a diagram once and not rehearsed as a decision algorithm; femoral hernia's higher strangulation risk is under-weighted.
What to do instead
Draw the myopectineal orifice from memory daily for a week, labelling the inferior epigastric vessels, and state for each hernia type: typical age/sex, relation to vessels, strangulation risk, and repair principle (tension-free mesh vs. Shouldice vs. emergency approach).
For hepatobiliary and pancreatic stems, candidates pick an operation without first interpreting the key laboratory/imaging pattern (e.g., choledocholithiasis vs. ascending cholangitis vs. gallstone pancreatitis) or without applying severity scoring (Tokyo guidelines, Atlanta classification, Child-Pugh/MELD) that determines timing and whether ERCP or surgery comes first.
Disease names are recognized, but the branch points that change management are not consolidated; pancreatitis severity and cholangitis urgency are commonly blurred.
What to do instead
Build decision trees for RUQ pain and for pancreatitis: first branch on severity and on presence of cholangitis/obstruction, then on timing (urgent ERCP within 24 h for cholangitis, cholecystectomy timing by severity). Rehearse the Child-Pugh and MELD components until reproducible.
In endocrine and breast items, candidates choose surgery before completing the biochemical or cytological workup - e.g., operating on a thyroid nodule without TSH and ultrasound risk stratification/FNA, or proceeding to axillary dissection without sentinel node status and receptor profile.
Surgical instinct plus memorable operations (total thyroidectomy, modified radical mastectomy) crowd out the staged diagnostic algorithm the question is testing.
What to do instead
For every endocrine/breast stem, force a three-column answer: 'biochemistry → imaging/cytology → operation'. Memorize which test is first-line for each organ (TSH then FNA for thyroid; aldosterone/renin for Conn; dexamethasone suppression for Cushing; triple assessment for breast).
On vascular questions, candidates cannot place the level of arterial occlusion from the clinical pattern (claudication distance, absent pulses, rest pain, acute vs. chronic) and therefore choose the wrong imaging or revascularization strategy; they also mismanage acute limb ischemia by delaying revascularization or giving thrombolysis where surgery is indicated.
Vascular examination findings are memorized as lists rather than as a map from pulse level to occlusion site; Rutherford classification for acute limb ischemia is often not applied.
What to do instead
Learn a pulse-to-lesion table (femoral/popliteal/pedal) and the Rutherford acute ischemia categories with the 'threatened vs. irreversible' boundary. For 15 vignettes, state occlusion level, imaging choice (duplex first, CTA if intervention planned), and revascularization modality before reading options.
Candidates answer pediatric and neonatal items with adult physiology - e.g., using adult fluid boluses (wrong mL/kg), ignoring that neonates tolerate less blood loss before shock, or misjudging which congenital anomaly requires immediate versus delayed operation (e.g., bilious vomiting in a neonate is a surgical emergency until proven otherwise).
Pediatric surgery is a small share of adult training, so adult defaults fill the gap; weight-based dosing and age-specific vital signs are not rehearsed.
What to do instead
Memorize a pediatric card: 10–20 mL/kg boluses, weight = (age+4)×2 kg approximation, age-specific heart and respiratory rates, and a red-flag list (bilious emesis, imperforate anus, absent femoral pulses, scrotal swelling). Drill 20 neonatal vignettes stating 'emergency vs. elective' explicitly.
In transplantation and surgical oncology items, candidates focus on the technical operation and ignore the selection/immunology layer - HLA matching and crossmatch, induction vs. maintenance immunosuppression, rejection timing and treatment, or the multidisciplinary sequence (neoadjuvant vs. adjuvant therapy, margin and lymph node principles) that the stem is actually asking about.
These topics are perceived as subspecialty knowledge and are deferred; candidates memorize operations but not eligibility criteria or the oncologic principles behind them.
What to do instead
Create two compact tables: (1) transplant - matching, crossmatch, hyperacute/acute/chronic rejection timing and management, common drug toxicities; (2) oncology - neoadjuvant vs. adjuvant indications, R0/R1/R2 meaning, sentinel node principles, and MDT sequence for breast, colorectal and gastric cancer.
On ethics, consent, error disclosure and Iranian regulatory items, candidates answer with general good intentions ('be honest', 'explain the risk') instead of the specific legal/professional rule - elements of valid informed consent, who may consent for an incompetent patient, mandatory reporting duties, documentation and disclosure procedure after an adverse event.
These questions look easy and are answered quickly without recalling the exact statutory or professional-code requirement; candidates also import foreign legal assumptions.
What to do instead
Memorize the consent elements (capacity, voluntariness, disclosure of material risks/alternatives, documentation), the hierarchy for surrogate consent, and the steps of open disclosure. Review the current Iranian medical council/health ministry regulations and hospital accreditation requirements on consent, error reporting and patient rights, and answer each vignette by naming the rule applied.
