Specimen-driven Ioarm

Specimen orientation establishes the spatial relationship between the excised tissue and its surgical margins. This allows the relevant edges to be identified accurately during rapid assessment and helps the surgical team connect an abnormal finding with the corresponding location in the operative field. Clear orientation therefore supports targeted, rather than indiscriminate, decisions about further tissue removal.

Rapid imaging or pathological assessment provides information while the operation is still in progress, rather than after closure. If disease is identified at a relevant edge, the surgeon may remove additional tissue during the same procedure. This timing can help reduce positive margins while limiting unnecessary excision of healthy tissue, supporting more precise oncologic surgery.

The intraoperative assessment supplies immediate guidance, whereas definitive histopathological evaluation remains part of the broader diagnostic process. Linking these stages allows findings from rapid assessment to inform the operation while preserving continuity with later pathology. This connection helps integrate real-time surgical decisions with the final evaluation of the resection specimen.

The workflow begins when the excised specimen is oriented and the relevant margins are identified. Rapid imaging or pathological assessment is then performed to evaluate those edges. Findings are communicated during the operation, allowing consideration of additional tissue removal before closure. The specimen subsequently remains connected to definitive histopathological evaluation.

Specimen-driven IOARM depends on coordinated communication among surgeons, radiologists, and pathologists. The surgeon provides the operative context, while imaging or pathology assessment supplies information about the specimen and its margins. Sharing these findings during the procedure helps the team interpret results in context and translate them into a more precise oncologic plan.

This approach is particularly relevant when the relationship between disease and the resection edge may affect whether further tissue should be removed. Its value lies in providing margin information before the operation ends, helping balance two competing goals: reducing the likelihood of a positive margin and avoiding unnecessary loss of healthy tissue. It therefore supports precision in oncologic procedures.
