Intraoperative consultation

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. 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.
