Evaluation of a new ultrasonic device in thyroid surgery: comparative randomized study

Randomized clinical trial of ultrasonic scissorsversusconventional haemostasis to compare complications and economics after total thyroidectomy (FOThyr)

“…Use of US has reduced the operating time in almost all published studies17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, including comparisons against LigaSure™. The present study confirmed that procedures in which US were used were quicker than those with CH.…”

“…In some studies11, 20, 21, 25, 31, transient hypocalcaemia was less common when US were used but, more often, rates were similar to those in the control arm7, 8, 9, 18, 22, 23, 27, 29, 30. Postoperative pain has rarely been evaluated, and only in a few studies12, 21, 27 did US reduce pain. The incidence of RLN palsy was also lower with US in some studies18, but more often has been comparable with that in the control arm17, 20, 22, 30, although the rate of this complication is so low that no study was large enough to detect differences.…”

Energy based surgical instruments : With particular focus on collateral thermal injury

“…Prospective studies indicate reduced operative times and costs for thyroidectomies when EBDs are used rather than C-A-T [112,133,134].…”

Safety and feasibility of a novel non-thermal device for tissue dissection: A preliminary study of the DD1 differential dissector

“…It is usually divided into sharp and blunt dissection, distinguished as slicing tissues (sharp) and teasing tissues apart (blunt). Some surgeons would add a third type, energy or coagulating dissection, in which electric current or another source of heat is used to simultaneously coagulate and divide tissues (2)(3)(4)(5)(6)(7)(8)(9)(10)(11).…”
