Identifying the parathyroids is compulsory for success of parathyroidectomy for parathyroid adenoma. Near-infrared autofluorescence devices have been proposed as useful intraoperative tools for the identification of parathyroid glands. The aim of the present study is to evaluate the correlation of PTeye autofluorescence device with biochemical data of parathyroid adenoma patients.
Identifying the parathyroids is compulsory for success of parathyroidectomy for parathyroid adenoma. Near-infrared autofluorescence devices have been proposed as useful intraoperative tools for the identification of parathyroid glands. Two approaches are available to surgeons to perform near-infrared autofluorescence: (i) Camera-based systems (CBS) and (ii) Probe-based systems such as PTeye™ (Medtronic, Minneapolis, MN).The aim of the present study is to evaluate the correlation of PTeye autofluorescence device with biochemical data of parathyroid adenoma patients.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Patients undergoing surgery for parathyroid adenoma will be enrolled in this study. Parathyroid glands will be identified with the application of autofluorescence device PTeye and the values obtained by the device after parathyroid gland recognition will be registered.
Procedure: parathyroidectomy
typical open parathyroidectomy
assess the correlation of PTeye values with biochemical data
Biochemical data included are pre- and postoperative parathyroid hormone, serum calcium, phosphorus and vitamin D levels
Time frame: intraoperatively and 1st postoperative day
