[Intraoperative detection of parathyroid tissue by semiconductor electrodes (author's transl)].

With miniature semiconductor electrodes of high sensitivity and special shape it is possible to charakterize diverse tissues during operation. The measured radioactivity of phosphorus reflects its enrichment and storage in the parathyroid tissue. The findings of 5 patients in whom clinically hyperparathyroidism was strongly suspected and who underwent surgery are reported. We have successfully localized parathyroidea adenomas in 3 patients, in 2 cases no adenoma could be found the storage of phosphorus 32 was normal. In all measurements we achieved a complete agreement with histological findings.
