Comparative study between cytological and histopathological analysis results of hemithyroidectomy in treatment of solitary thyroid nodule

Aim The aim of this study was to compare the outcome results of cytological examination by fine‑needle aspiration cytology to histopathological examination by hemithyroidectomy in patients with solitary thyroid nodule. Patients and methods We prospectively reviewed 30 consecutive patients had primary hemithyroidectomy for management of solitary thyroid nodule, carried out over a year (from January 2017 to January 2018) at Assiut University Hospital Surgical Department. Results There were 24 women and six men with a mean age 34.67 years (range, 19–70 years). Preoperative findings of fine‑needle aspiration cytology of these were: 17 (56.7%) patients had colloid nodule, 10 (33.3%) follicular neoplasm, and three3 (10%) hyperplastic nodule. Biopsied lesions were found to be malignant on pathological evaluation in two (6.6%) patients with follicular neoplasm, hemithyroidectomy was adequate definitive treatment in 28 of 30 (93.3%) patients. Conclusion In a review of the experience at Assiut University Hospital Surgical Department, hemithyroidectomy was the optimal initial and definitive surgical approach for most patients with benign and indeterminate cytology and had undergone thyroid surgery for suspicion of cancer.
