Reoperation after local excision of differentiated thyroid cancer / 中国普通外科杂志

ABSTRACT

Objective To study the choice of initial operative approach for thyroid nodule and the necessity of reoperation after local excision of differentiated thyroid cancer.Methods Clinical data of 138 patients with differentiated thyroid cancer after local tumor excision had reoperation at our hospital during a period of four year were retrospectively reviewed.All the reoperations were bilateral thyroidectomy and cervical lymph node excision.Results There were 76.8% patients with residual cancer in thyroid and cervical lymph node.There were 23 patients(16.7%) with recurrent laryngeal nerve injury that included 22 cases with unilateral and 1 case with bilateral injury after the initial operation,and 19 of the 23 patients with recurrent laryngeal nerve injury recovered after nerve repair.After thyroid reoperation,3 cases(2.2%) had recurrent laryngeal nerve injury,2 cases(1.4%) had partial parathyroid gland injury,2 cases(1.4%) had superior laryngeal nerve injury,but there were no cases of esophageal injury or postoperative bleeding.Conclusions The incidence of residual cancer is high after local excision for differentiated thyroid cancer,therefore,reoperation with bilateral thyroidectomy and cervical lymph node excision is necessary.
