Rapid Intraoperative PTH (ioPTH) assay in parathyroid surgery

Intra-operative PTH Monitoring Now Available for Parathyroid Surgery in Auckland

Patients undergoing parathyroid surgery in Auckland can now benefit from a significant advance in endocrine surgical care. Dr John Chaplin has introduced intra-operative parathyroid hormone (ioPTH) monitoring for parathyroidectomy patients at Gillies Hospital, the first time this technology has been available locally.

This innovation allows surgeons to measure parathyroid hormone (PTH) levels during the operation, helping confirm that the over-active parathyroid gland responsible for hyperparathyroidism has been successfully removed.

Rapid Results During Surgery

The new system uses the NBCL Connect™ immunoassay analyser, supplied by Abacus Dx Ltd, which provides a PTH result in approximately five minutes.

Parathyroid hormone has a very short half-life in the bloodstream. Once an abnormal gland (parathyroid adenoma) is removed, the hormone level falls rapidly. By measuring this drop during the operation, surgeons can confirm that the source of excess hormone has been successfully treated.

Previously, blood samples often needed to be sent to a central laboratory, which meant significantly longer waiting times for results. The new on-site analyser allows the surgical team to receive results almost immediately while the patient is still in theatre.

Benefits for Patients with Hyperparathyroidism

Introducing intra-operative PTH monitoring offers several advantages for patients undergoing parathyroidectomy:

• Greater confidence that the operation has been successful

• Ability to detect additional parathyroid adenomas or multi-gland hyperplasia during the same procedure

• Reduced likelihood of needing a second operation

• Support for focused or minimally invasive parathyroid surgery

This technology is widely used in leading international endocrine surgery centres and is considered an important tool in achieving high cure rates for primary hyperparathyroidism.

Advancing Parathyroid Surgery in Auckland

The introduction of ioPTH monitoring at Gillies Hospital represents an important step forward for patients requiring parathyroid surgery in New Zealand.

By combining specialist endocrine surgery with rapid intra-operative hormone monitoring, Dr John Chaplin and the team at Gillies Hospital are bringing internationally recognised best practice to patients in Auckland.
