CASTELLANOS CORONEL, Luis Moisés et al. Comparison of vessel sealing system and conventional ligation in thyroidectomy. Salus [online]. 2014, vol.18, n.1, pp.13-17. ISSN 1316-7138.

Every day, it is more common in thyroid surgery, the use of electromechanical systems, as hemostatic method in thyroid surgery, as opposed to conventional hemostasis. A comparative study between blood vessel sealing system LigaSure^® and conventional hemostasis with ligation was carried out. 113 patients records who underwent thyroid surgery, evaluating preoperative studies, surgical indication, intra and postoperative complications, reoperation, surgical time, days of hospitalization and pathological anatomy results were analized. Between january 2002 and december 2012, 113 thyroidectomies were performed; 52 with the usual ligature method and 61 patients with the LigaSure^® hemostatic method. The average age was 41.3 and 46 years respectively; papillary carcinoma was diagnosed in 19,2% and 22,9%. The duration of surgery in the conventional hemostasis group was 78.8 minutes and 74.4 minutes in the vessel sealing group, with a postoperative drainage of 85 and 71 cc for each group. The days of hospitalization were 3.1 and 2.19. In terms of complications: postoperative hematoma with reoperation (2 cases in the conventional group and 1 case in the LigaSure^® group); recurrent laryngeal nerve lesion (1 case in each group), transient hypocalcemia (3 cases in the conventional group and 1 case in the LigaSure^® group); one patient required tracheostomy in the LigaSure^® group. In conclusion, hemostasis in thyroidectomy using the LigaSure^® vessel sealing method, allows the realization of surgery in comfort and safety with a slight advantage to conventional methods.
