Results of total thyroidectomy in the treatment of hyperthyroidism

Abstract

Introduction: Surgery is used in the management of hyperthyroidism in cases of large goiter, failure of medical treatment or social indication of definitive treatment. Aim: To analyze the results of the treatment of hyperthyroidism by total thyroidec­tomy (TT) regarding to thyroid function. Material and methods: Retrospective study of 26 patients with hyperthyroidism, operated on the Hospital de la Plana during 2015-2018, with a follow-up of 36 months. After a descriptive and inferential statistical study, the probability of recurrence of hyper­thyroidism was analyzed using the Kaplan-Meier method, and the Cox model was used to adjust the effects on recurrence of the different variables. Results: 73.1% had thyroid normofunction; in 19.2% there was hyperfunction, and in another 7.7% there was hypofunction. The average survival time (normofunction) was 25,87 months (CI: 17,52-34,21). In the study of survival with the log-rank depen­ding on the pathological results and complications, there are no statistically significant differences in the survival of both groups. Discussion: This coincides with other published works. Conclusion: TT is an effective method of treatment for hyperthyroidism, with a low incidence of complications. However, we have not found any variable that allows us to predict the result.
