Comparison of total thyroidectomy, bilateral subtotal thyroidectomy and Dunhill operations in the treatment of benign...

The surgical treatment of benign thyroid disease is still controversial. Many treatment modalities have been described for the surgical management of various thyroid diseases, including excision, bilateral subtotal thyroidectomy (BST), near-total thyroidectomy, and total thyroidectomy (TT).

Hospital records were reviewed for 2863 patients who underwent thyroid surgery for presumed multinodular goiter (MNG) between 1990 and 2009. However, due to the inefficiency of the hospital archive system, we were able to access detailed personal and surgical information for only 803 patients.

Of the 803 patients, 227 (28.3%) underwent DP, 228 (28.4%) BST and 348 (43.3%) TT operations. While there were no complications in 683 (85.1%) of the 803 operations, complications developed with 120 (14.9%). A definite difference between TT and the other (BST and DP) types of operation in relation to complications. The duration of hospital stay was 2.2±0.4 days for the BST group, 2.2 ± 0.4 days for the DP group and 2.3 ± 0.7 days for the TT group. There was a significant difference among all three groups. Recurrence rates of the operations performed were 35 (15.3%), 20 (8.8%) and 4 (1.15%), respectively, for BST, DP and TT. There was significant difference between the recurrence rates of TT and BST, and between TT and DP.

When the frequency of complications in recurrent operations and the malignity possibility of the thyroid tissue left behind are taken into consideration, we believe that TT will be more beneficial in the surgical treatment of benign thyroid disorders.
