NCT01598727

Brief Summary

Hypothesis: Intraoperative use of near infrared fluorescent imaging technology and detection of Methylene Blue fluorescence will improve outcomes following thyroid and parathyroid surgery. Aims: The aims of this phase of the study are to determine the feasibility of using near infrared fluorescent technology in the detection of parathyroid tissue and its differentiation from adjacent soft tissue during surgery on parathyroid glands. Objectives of the phase I study:

  1. 1.To familiarise surgical teams with the intraoperative use of the 'Fluobeam(TM)' device (Fluoptics).
  2. 2.To understand the patterns (onset, intensity and duration) of fluorescent staining of normal parathyroid glands, thyroid glands and other soft tissue structures encountered during parathyroidectomy.

Outcome Measures

Primary Outcomes (1)

  • Determine patterns of fluorescence from soft tissue structures in the neck

    This is a proof of principle study aimed to demonstrate that the patterns of Methylene Blue emitted fluorescence from the parathyroid glands, thyroid glands and other soft tissue structures in the neck such as lymph glands are distinct and can be used to differentiate between them at surgery. The fluorescence from the various structures will be recorded as 'no', 'mild' and 'yes'.
