Ligasure vessel sealing system versus conventional vessel ligation in thyroidectomy.
OBJECTIVE
The Ligasure Vessel Sealing System (LVSS) is a new surgical technology which has been used to secure haemostasis in various fields of surgery. There is little information in the literature about the use of the LVSS in thyroid surgery and the results of these studies are controversial. The aim of this study was to report our experience with the LVSS in thyroid surgery and to compare it with our experience with conventional vessel ligation.


METHODS
The non-randomized retrospective review included 403 consecutive patients who underwent primary thyroid surgery. A conventional suture-ligation technique was used in 199 patients (conventional group) and the LVSS was used in 204 patients (ligasure group). The following data were collected: patients' demographics, thyroid pathology, type of thyroidectomy, operating time and complications.


RESULTS
The mean operating time for lobectomy, subtotal thyroidectomy and total thyroidectomy was significantly shorter in the Ligasure group compared with the conventional group. Average saving in operating time in the Ligasure group was 25.8 minutes (95% CI 19.5-32.2; p < 0.0001) with relative reduction being 26.6%. Among all types of complications only postoperative transient hypoparathyroidism demonstrated a significantly lower incidence in the Ligasure group (2.5% vs 7.0%; p = 0.022).


CONCLUSIONS
We found that the LVSS is a safe method with minimal complications in thyroid surgery. Use of the LVSS for all types of thyroidectomy ensures a significantly shorter operating time.
