Which tool is used for the proper handling of sentinel nodes during surgery?

Sentinel nodes are critical in cancer surgeries, particularly in procedures like sentinel lymph node biopsy, as they indicate potential metastasis. The correct handling of these nodes is essential for accurate pathological evaluation and to ensure that the surgical site is free from cancer cells.

Using a specimen cup for the handling of sentinel nodes allows for safe and contamination-free transfer of the tissue from the surgical area to pathology. The specimen cup is designed to preserve the integrity of the tissue, protecting it from damage that might occur if forceps, scissors, or scalpels were used to directly manipulate the nodes. Furthermore, specimen cups are often designed to be airtight, which can help in preserving the tissue for proper examination.

In contrast, instruments like scalpels, forceps, and scissors, while important in various surgical tasks, are less suited for the delicate handling required for sentinel nodes. These tools could potentially cause trauma to the tissue, leading to inaccurate assessments when the nodes are examined post-surgery. Therefore, the use of a specimen cup is the most appropriate choice for handling sentinel nodes during surgical procedures.
