Description of intervention(s) / exposure
BRIEF NAME:
Assessing Benefits of Near Infrared Autofluorescence Detection for Identifying Parathyroid Glands during Endocrine Surgery

MATERIALS USED:
The intervention will evaluate whether the PTeye (Medtronic, Santa Barbara, CA) a probe-based near infrared autofluorescence detection device that consists of a console, a handheld fibre optic probe, a foot pedal and an external power supply, can assist surgeons to identify PGs during thyroid and parathyroid operations confidently.

PROCEDURE:
A standard thyroid or parathyroid operation will take place and use of he PTeye will occur if the patient has been randomised to the intervention arm
The handheld fibre optic probe is initially applied to the thyroid gland to record a “baseline” for the device. This will take approximately 10 seconds. The probe will subsequently be used on tissue that is thought to be parathyroid tissue.
The use of the PTeye would be expected to add another 5 minutes to the operative time.

WHO WILL DELIVER:
Endocrine surgeons as Alfred Health

TRAINING
Surgeons have been provided training by the inventor of the device from Vanderbilt University, Nashville, TN. The Principal Investigator has also spent time at Vanderbilt University with a surgeon who has had the greatest experience in the use of the PTeye.

MODE OF DELIVERY:
The intervention will occur with an individual surgeon and patient at the time they are undergoing the relevant endocrine operation.

NUMBER OF TIMES:
Approximately 6 times per week, dependent on the individual surgeon’s schedule

LOCATION OF INTERVENTION:
Alfred Hospital operating theatres
Intervention code [1] 327666 0
Treatment: Surgery
Comparator / control treatment
A standard thyroid or parathyroid operation will be undertaken without any form of imaging being used at the time of surgery.

Types of thyroid surgery include removal of half or the whole thyroid gland. At the time of surgery, the parathyroid glands are identified and preserved. This is currently done by visual identification of the gland(s) by the surgeon.

For parathyroid surgery, any abnormal parathyroid gland will be removed.
Control group
Active

Outcomes
Primary outcome [1] 336916 0
The primary endpoint of this study is to evaluate the confidence level of surgeons in identifying parathyroid glands during thyroid and parathyroid surgery before and after using the PTeye

This information is recorded at the time of surgery
Secondary outcome [1] 430151 0
Post-operative hypoparathyroidism rates
Timepoint [1] 430151 0
PTH levels will be checked at Day 0,Day 1, 2 weeks and 3 months post surgery
Secondary outcome [2] 430968 0

Timepoint [2] 430968 0
This will be recorded intraoperatively
Secondary outcome [3] 430969 0
Confidence of surgical trainees in identifying parathyroid glands
Timepoint [3] 430969 0
This will be assessed intraoperatively

Eligibility
