NCT05784792

Brief Summary

Preoperative preparation of patient with Basedow's disease is crucial to avoid severe thyrotoxicosis resulting from leakage of thyroid hormone into the circulation at the time of surgery. Moreover, hyperthyroidism-related hypervascularization and tissue fragility caused by Basedow's disease thyroiditis may cause intraoperative bleeding that can reduce the visualization and preservation of parathyroid glands and laryngeal nerves with subsequent higher risk of related morbidity including neck hematoma, hypoparathyroidism and vocal cords paresis. Although some endocrine surgeons administer before surgery Lugol solution to decrease thyroid gland vascularity in Basedow's disease, there is still not an agreement on its effectiveness. The aims of the present trial are to evaluate the impact of pre-operative short-term Lugol solution treatment (7 days) on surgical outcomes through modification of thyroid vascularity and surgical related morbidity, in patients with Basedow's disease.

Outcome Measures

Primary Outcomes (1)

  • Intra and post-operative blood loss (mL).

    Blood loss volume (mL) as the amount of blood in the suction bottle and that absorbed by gauzes used during surgery was measured (volume calculated from the difference between dry gauzes weight and soaked gauzes weight). Evaluation of differences (if any) in this outcome in the two groups of the study (Lugol assumption/no Lugol assumption).

    Intra and post-operative bleeding (1st and 2nd day after surgery)

Secondary Outcomes (3)

  • Post-operative laryngeal nerves palsy.

    Laryngeal ultrasound on 1st and 2nd day and indirect laryngoscopy in case of dysphonia

  • Intra and post-operative thyrotoxicosis.

    During surgery and on 1st and 2nd day after surgery

  • Post-operative hypocalcemia (hypoparathyroidism, hungry bone syndrome).

    Blood sample on 1st and 2nd day after surgery.

Other Outcomes (9)

  • Change of ultrasound thyroid vascularization: blood flow velocity (v) variation (mm/sec).

    Thyroid US doppler data: 7 days before surgery and the day before surgery (after 1 week).

  • Change of ultrasound thyroid vascularization: resistance index (RI) variation.

    Thyroid US doppler data: 7 days before surgery and the day before surgery (after 1 week).

  • Change of ultrasound thyroid vascularization: pulsatility index (PI) variation

    Thyroid US doppler data: 7 days before surgery and the day before surgery (after 1 week).

  • +6 more other outcomes
