A surgeon removed section of tissues how would he confirm that cut margin
doesn't contain any suspicious tissue intraoperatively?
1) Punch biopsy
2) Brush biopsy
3) Frozen section
4) Exfoliative cytology
๐ Explanation:
The frozen section procedure is the examination of tissue to make a rapid microscopic diagnosis of a specimen while surgery is taking place. It is often used in oncological surgery to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin.
The technical name for this procedure is cryosection. The report given by the
pathologist is usually limited to a "benign" or "malignant diagnosis, and
communicated to the surgeon operating via intercom. When operating on a previously confirmed malignancy, the main purpose of the pathologist is to
inform the surgeon if the surgical margin is clear of residual cancer, or if
residual cancer is present at the surgical margin
Advantages of frozen section biopsy:
If more tissue is needed to make an accurate diagnosis, the surgeon is able to
obtain an additional sample, avoiding a second operation.
If the tissue is determined to be cancerous and is amenable to surgery, the mass
can b removed at that time
If the tissue is determined to be benign (not cancerous), then the mass may not
always need to be removed and the surgery can end.
