Totally endoscopic vs open thyroidectomy for differentiated thyroid cancer / 中华普通外科杂志

ABSTRACT

Objective:To compare toally endoscopic thyroidectomy(TET) with open thyroidectomy(OT) in the treatment of differentiated thyroid cancer.Methods:Data of 190 patients at Liuzhou People's Hospital from Jul 2017 to Dec 2019 were analyzed. Patients were divided into endoscopic surgery group ( n=95) and open surgery group ( n=95). Results:The operation time and the hospital stay in endoscopic group were longer than that in open surgery group[(153±25) min vs. (116±17) min, (5.56±1.08) d vs.(5.08±1.04) d, t=11.827，3.083， both P<0.05)]. There was no significant difference in intraoperative blood loss [(33±14) ml vs. (37±16) ml, t=-1.851 P>0.05], recurrent laryngeal nerve paralysis, hypoparathyroidism and wound complications (4% vs. 9%, 9% vs. 15%,1% vs. 3%, all P>0.05). There was no significant difference in the number of central lymph node dissection between the two groups (6.12±3.54 vs. 6.35±4.75, t=-0.404, P<0.05). The length of scar in endoscopic group was shorter [(3.03±0.27) cm vs. (6.47±0.53) cm, t=-56.138, P<0.05), and the postoperative cosmetic score evaluated by the patients was higher (8.76±0.75 vs. 7.39±0.76, P<0.05), than those in open group. There were no tumor recurrence nor metastasis in neither group by short term follow-up. Conclusions:TET is similar to OT on clinical curative effectiveness for differentiated thyroid carcinoma while carries a better cosmetic result .
