RESUMO
Objective To compare the clinical effect of endoscopic thyroidectomy and open thyroidectomy in the treat-ment of benign thyroid diseases. Methods A total of 120 patients with benign thyroid diseases were selected from March 2015 to June 2017 in the Third Affiliated Hospital of Xinxiang Medical University. The patients were divided into endoscopic opera-tion group(n = 62)and open operation group(n = 58)according to the treatment methods. The patients in the open operation group were treated with conventional open thyroidectomy,and the patients in the endoscopic operation group were treated with endoscopic thyroidectomy. The operation time,intraoperative bleeding volume,postoperative drainage volume and hospitalization time were recorded in the two groups;and the intraoperative and postoperative complications were observed. The pain of the pa-tients in the two groups was evaluated by visual analogue scale(VAS)at the time points of 6,12 and 24 hours after operation. The cosmetic satisfaction of the patients in the two groups was evaluated by numerical scoring system(NSS)at the time points of 1 and 3 months after operation. Results The operation time and hospitalization time in the endoscopic operation group were significantly shorter than those in the open operation group(P < 0. 05),and the intraoperative bleeding volume and postopera-tive drainage volume in the endoscopic operation group were significantly lower than those in the open operation group(P <0. 05). The VAS score of pain in the endoscopic operation group was significantly lower than that in the open operation group at the time points of 6,12 and 24 hours after operation(P < 0. 05). The NSS score in the endoscopic operation group was sig-nificantly higher than that in the open operation group at the time points of 1 and 3 months after operation(P < 0. 05). The in-cidence of complications in the endoscopic operation group and the open operation group was 12. 90％(8 / 62)and 39. 66％(23 / 58)respectively,the incidence of complications in the endoscopic operation group was significantly lower than that in the open operation group(χ2 = 11. 210,P < 0. 05). Conclusion Endoscopic thyroidectomy is reliable in the treatment of benign thyroid diseases. It has the advantages of small trauma,short operation time,quick recovery,light postoperative pain,small sur-gical scar and fewer complications and so on.
