intraoperative frozen section
Rapid pathological examination of tissue during surgery to guide immediate surgical decision-making.
Full Definition
Intraoperative frozen section is a rapid histopathological technique used during gynecologic surgery to provide immediate diagnostic information that influences surgical decision-making. The procedure involves freezing tissue samples, cutting thin sections, and staining them for immediate microscopic examination by a pathologist. In gynecologic surgery, frozen sections are commonly used to assess lymph node status, determine malignancy in ovarian masses, evaluate surgical margins, and guide the extent of surgical resection. While generally accurate, frozen section has limitations and may require permanent section confirmation for definitive diagnosis.
Usage
Usage note: Note limitations of frozen section and need for permanent section confirmation when relevant.
