Intraoperative consultation, also quick section and frozen section, is when a surgeon requests an opinion during an operation so that they can appropriately manage a patient. It is abbreviated IC.

Why intraoperative consultations are done

Reasons why IC are done:[1]

  1. Determine diagnosis & appropriate extent of operation ~ 50%.
  2. Margins status - 15%.
  3. Triage tissue ~ 10%.
  4. Inform family ~ 8%.
  5. Sufficient tissue? ~ 8%.

Why intraoperative consultations may be refused

  • Tissue is the issue - not enough of it.
  • Infectious case.
  • Management - it won't make a different.
    • Diagnosis won't make a difference.
    • Cannot make the diagnosis.
      • Bone tumours.
