Completion thyroidectomy can be done safely after thyroid lobectomy in patients with thyroid carcinoma
The background of the study. Patients
with athyroid nodule are often treated by removal of the thyroid
lobe containing the nodule (thyroid lobectomy). However, if the
nodule proves to be a follicular or papillary carcinoma, removal
of the other thyroid lobe-so-called completion thyroidectomy-is
often recommended. This study was done to determine the safety of
completion thyroidectomy.
How the study was done. The study subjects were all 36 patients (32 women, 4 men; mean age, 44 years) who underwent thyroid lobectomy and then completion thyroidectomy by one surgeon between 1997 and 2000.
The results of the study. The diagnoses at the initial operation were follicular variant of papillary carcinoma in 29 patients (80 percent), follicular carcinoma in 6 patients (17 percent), and Hurthle-cell carcinoma in 1 patient (3 percent).
The completion thyroidectomy, performed 2 to 103 days (mean, 43) after the initial thyroid lobectomy, revealed thyroid carcinoma in 20 of the 36 patients (56 percent). The pathological diagnosis was follicular variant of papillary carcinoma in 18 patients (50 percent), follicular carcinoma in 1 patient (3 percent), and Hurthle-cell carcinoma in 1 patient (3 percent). No tumor was found in 16 patients (44 percent). Few patients had any permanent side effects after either operation.
The conclusions of the study.Completion thyroidectomy can be performed safely a few days or many weeks after initial thyroid lobectomy. The operation reveals thyroid carcinoma in approximately 50 percent of patients.
