Specimen Retrieval
Process of extracting resected tissue from the operative field while maintaining specimen integrity and preventing tumor spillage.
Full Definition
Specimen retrieval is a critical component of oncologic surgery that involves the safe extraction of resected tissue while preserving specimen integrity for pathological analysis and preventing tumor cell spillage. In minimally invasive surgery, this typically requires the use of extraction bags or specimen pouches to contain the specimen during removal through small incisions. Proper technique prevents port site metastases and maintains the oncologic benefits of the procedure. The choice of retrieval method depends on specimen size, tumor type, and operative approach, with emphasis on avoiding specimen fragmentation or contamination.
Usage
Usage note: Emphasize containment methods used to prevent spillage, especially in minimally invasive procedures.
