双侧结节性甲状腺肿手术方式的探讨

目的 探讨双侧甲状腺全切除/近全切除术治疗双侧结节性甲状腺肿是否安全可行.方法 2003年1月至2006年12月311例拟诊双侧结节性甲状腺肿者分为A、B两组;A组130例行双甲全/近全切术;B组181例行双甲次全切或/和大部切除术.结果 A、B两组各有6例和2例术中冰冻报告良性,但术后石蜡切片报告为乳头状癌.A组不需再手术,B组需再手术;两组术后各3例(2.42%,3/124 vs.1.68%,3/179)有暂时性声嘶,差异无统计学意义(P=0.48).术后2月A组2例有音调改变,无法发高音,喉镜示双侧声带活动好;B组1例有声嘶,喉镜示一侧声带活动减弱.两组术后各有11(8.87%,11/124)和9例(5.03%,9/179)术后48 h内有低钙血症,差异无统计学意义(P=0.16).两组无永久性甲状旁腺功能减退.B组术后2例(1.12%,2/179)因出血需再手术.A组术后无结节性甲状腺肿复发,B组12例复发(6.70%,12/179),差异有统计学意义(P=0.02).结论 双甲全/近全切除术可减少结节性甲状腺肿术后复发率和再手术率,且并发症并无增加,是安全可行的.

Total thyroidectomy for bilateral multinodular goiter

Objective To evaluate the safety and rationality of total/near total bilateral thyroidectomy(TBT) for patients with bilateral multinodular goiter(BMG). Methods From January 2003 to December 2006,311 BMG cases were preoperatively divided into two groups, 130 cases in group A underwent TBT, and 181 cases in group B were treated with subtotal/partial bilateral thyroidectomy. Results There were 6 and 2 eases in group A and group B respectively diagnosed by intraoperative frozen biopsy as BMG, but identified as papillary carcinoma by final pathology. Hence the 6 cases in group A avoided reoporation, while the 2 cases in group B underwent a resection of the remnant gland. Transient hoarseness developed in 3 (2.42%, 3/124) and 3 (1.68%, 3/179) eases in group A and group B respectively (P =0.48). Transient hypocalcemia developed in 11 (8.87% ,11/124) and 9(5.03% ,9/179) cases in group A and group B respectively(P =0.16). There was no postoperative goiter recurrence in group A, but recurrence developed in 12 cases (6.70%,12/179) in group B(P=0.02). Conclusions Total bilateral thyroidectomy is safe and rational for the management of bilateral thyroid goiter.
