A Tool for Thyroid and Breast Punch Biopsy

Abstract

Background. Diagnosis of thyroid and mammary gland neoplasms is a persisting challenge. The common punch biopsy techniques exhibit significant drawbacks responsible for biasing the gland tumour inspection. The authors propose technical and methodological novelties in punch biopsy for improving the sensitivity and accuracy of neoplasm differential diagnosis in surgery.Materials and methods. A control cohort of 1406 patients had a conventional punch biopsy without ultrasonic guidance, whereas the study cohort of 1870 patients had puncturing with a novel device suitable for voluminous thyroid and mammary gland neoplasm biopsy.Results. A novel punch biopsy method is developed basing on the oscillation amplitude and tissue optical density determination. The novel puncture appliance and technique allowed an accuracy improvement of voluminous thyroid and mammary gland neoplasm puncture up to 90 %. No complications of thyroid neoplasm punch biopsy were observed in the study cohort. The control group exhibited the complications of impaired swallowing, local inflammation and haematomas at the puncture site.Discussion. The punch biopsy technique based on the pulse oscillation amplitude and optical tissue density measurement was proved to allow an earlier detection of voluminous neoplasms compared to visual inspection, while an additional canal allows concurrent biopsy of the lesion-adjacent tissue and the assessment of therapeutic efficacy and disease progression.Conclusion. Creative surgical approaches to punch biopsy based on emitter and optic sensor-geared pulse optometry and their implementing tool have been developed. The method improves the efficiency and accuracy of voluminous neoplasm differential diagnosis, provides control of treatment efficacy and prevents false positive and false negative detections.
