BACKGROUND: Multinodular goiter is a common disease in population. If only one thyroid lobe is affected, hemithyroidectomy may be preferred to reduce complication and hormone replacement therapy. However, completion thyroidectomy may be required later. The aim of the study was to evaluate the role of completion thyroidectomy in patients who develop nodules after hemithyroidectomy and we aimed to find the ratio of patients who required hormone replacement for permanent hypothyroidism.
MATERIALS AND METHODS: The patients who underwent hemithyroidectomy for benign nodular goitre between January 2012 and June 2017 were analysed. The age of the patients, gender, number of nodules and dimension of the largest nodule, preoperative fine needle aspiration biopsy results, and postoperative histopathology findings were recorded. The need for completion thyroidectomy and need for postoperative L-thyroxine treatment were based on these parameters.
RESULTS: A total of 170 patients were included in the study. During the follow-up period new nodule or progression in existing nodule was observed in 23% (39 patients) of the cases. Permanent hypothyroidism requiring L-thyroxine treatment was observed in 31% (53 patients) of the cases. In this study, young age, multiple nodules and toxic nodular goitre diagnosis were noted to be independent risk factors that contributed to progression diseases in cases operated for benign nodular goitre.
CONCLUSIONS: Due to low reoperation risk and acceptable permanent hypothyroidism rates, hemithyroidectomy is a viable option for benign goitre cases. The patients should be on follow-up for possible complications, especially hypothyroidism, for at least a year.
