operative field contamination
Unintentional introduction of tumor cells into clean tissue planes during surgery.
Full Definition
Operative field contamination occurs when cancer cells are inadvertently introduced into previously clean tissue planes or body cavities during surgical procedures. This can result from instrument contamination, tumor cell spillage, or inadequate surgical technique. Contamination events may require immediate corrective measures such as copious irrigation, instrument changes, and extension of resection margins. The occurrence of operative field contamination must be documented as it may influence staging, prognosis, and adjuvant treatment decisions. Prevention strategies include careful tissue handling, frequent instrument changes, and isolation techniques.
Usage
Usage note: Document the source of contamination and corrective measures taken immediately.
