Condition thyroid tumor
Treatments ultrasonic scissors (ethicon), bipolar electrosurgical instruments (medtronic) (sls- clips)
Phase phase 3
Sponsor Nantes University Hospital
Start date March 2012
End date October 2014
Trial size 1350 participants
Trial identifier NCT01551914, RC11_0148


The aim of our study is to evaluate the ultrasonic scissors (Harmonic Focus Ethicon Endo-Surgery Laboratory) as a device of hemostasis in thyroid surgery (total thyroidectomy) by cervicotomy, and to show a decrease in transient hypoparathyroidism compared to conventional techniques of haemostasis (clips, ligatures, and bipolar coagulation). Secondary objectives of the study are the evaluation of (i) recurrent nerve morbidity, (ii) postoperative bleeding, (iii) postoperative pain, (iv) cost of both techniques (microcosting), (v) the overall cost of the techniques at six months, (vi) a linking of costs and medical outcomes and (vii) an estimation of the potential impact of new technology on the organization of operating rooms (operating time).
