NCT06222606

Brief Summary

The study aims to test if use of autofluorescence imaging (AF) reduces the risk of developing hypoparathyroidism (hypoPT) following surgery for thyroid cancer, either total thyroidectomy (TT) or completion hemithyroidectomy (cHT).

Outcome Measures

Primary Outcomes (1)

  • Hypoparathyroidism

    Proportion of patients who develop transient or permanent hypoPT requiring medical treatment with active vitamin D. HypoPT is diagnosed and treated according to protocol.

Secondary Outcomes (5)

  • Permanent hypoparathyroidism

    6 and 12 months

  • Intra-operative reduction in plasma concentration of PTH.

    During surgery

  • Time to resolution of transient hypoPT.

    12 months

  • Number of days hospitalized

    30 days

  • Oncological and composite outcomes

    2 years

Other Outcomes (5)

  • Histology report

    1 week

  • Extent of surgery

    During surgery

  • Complications

    30 days

  • +2 more other outcomes

Study Arms (2)

Control group

NO INTERVENTION

Patients randomized to the experimental group will have surgery performed in the exact same manner as in the control group.

Surgery with EleVision IR camera system

EXPERIMENTAL

In the experimental group, the surgeon will use the EleVision IR camera system (Medtronic, USA) to visualize PGs during surgery. The surgeon will use AF at minimum two timepoints on each side of the neck: First, when the thyroid lobe is exposed and mobilized, and secondly after removal of the thyroid lobe. This is repeated in the contralateral side of the neck in case of TT. If a central neck dissection is performed, the specimen is also examined with AF following removal. Autotransplantation of inadvertently removed PGs may be performed after frozen section histology.

Procedure: Surgery with autofluorescence

Interventions

In the experimental group, the surgeon will use the EleVision IR camera system (Medtronic, USA) to visualize parathyroid glands during surgery.
