Background:
The necessary extent of thyroid resection in benign nodular goiter is under debate. The aim of our study was to compare the long-term outcome of different thyroid resection modes with special interest in the incidence of recurrent nodules and the use of oral thyroid hormone medication.
Materials And Methods:
We performed a follow-up examination of 109 patients (23 men and 86 women) having been operated for benign nodular goiter at our department 10 years ago. Unilateral resections and function-preserving resections of at least one thyroid lobe were classified as function-preserving (FP). Total thyroidectomy, Dunhill's operation and bilateral subtotal thyroidectomy were rated as standard-radical (STR). On follow-up, we recorded current oral thyroid hormone medication, thyroid function tests and ultrasound of the neck.
Results:
Seventy-three patients had FP resection (67%), while 36 were STR-operated (33%). The subsequent medical treatment was performed by dedicated endocrinologists (n = 19), internists (n = 11) or primary-care physicians (n = 59). Twenty patients had no medical attendance. Recurrent nodules were found in 13 cases in the FP group (18.6%) vs. 3 cases in the STR group (2.5%; p < 0.001). In both groups, about 80% of patients used thyroid hormone medication 10 years after operation.
Conclusion:
There was no advantage in thyroid function tests nor lesser medication in the FP group. The risk for recurrent nodules was significantly higher in the FP than in the STR-operated patients.
