intraoperative staging
Pronunciation: in-trah-OP-er-ah-tiv STAY-jing
The assessment of tumor extent and spread during surgery to guide immediate surgical decisions and treatment planning.
Full Definition
Intraoperative staging involves the real-time assessment of tumor characteristics, extent of local invasion, and presence of metastatic disease during surgical exploration. This process includes visual inspection, palpation of structures, evaluation of lymph nodes, assessment of peritoneal surfaces, and may incorporate techniques such as frozen section analysis, ultrasound, or other imaging modalities. The findings directly influence surgical decision-making, including the extent of resection required, feasibility of curative versus palliative approaches, and need for additional procedures such as lymphadenectomy or multivisceral resection.
Usage
Usage note: Distinct from preoperative staging; focuses on surgical findings that impact immediate decisions.
