Analysis of surgical complications of thyroid diseases: results of a single institution.

Background: The purpose of this study is to compare the complications of different types of thyroidectomy for benign and malignant thyroidal diseases.

Methods: Between January 2001 and March 2006, 982 patients underwent thyroidectomy in single institute. A retrospective analysis was performed on demographic characteristics and pathology reports of patients, complications of surgery as well as the follow-up of patients. Sixty patients could not be fully followed up and were excluded.

Results: The types of the surgical procedures were as follows; 451 (48.9%) total, 137 (14.9%) subtotal, 60 (6.5%) near-total thyroidectomy and 274 (29.8%) lobectomy with isthmectomy. In the benign group, temporary recurrent laryngeal nerve injury (RLNI) was the most common complication in patients with toxic diffuse goiter (TDG 2%) while this complication occurred in patients with differentiated thyroid cancer (DTC 1.5%) in the malign group. Permanent RLNI in benign thyroidal diseases was seen more commonly in patients with toxic multinodular goiter (1.3%). In benign thyroidal diseases, temporary hypoparathyroidism (THPT) was mostly found in patients with TDG (8%), whereas in malignant thyroidal diseases this was found more in patients with DTC (2%). Permanent HPT (PHPT) in benign thyroidal diseases was observed more commonly in patients with multinodular goiter (0.9%). In malignant thyroidal diseases, it was more frequently observed in patients with DTC (0.5%). Infective complications after thyroid surgery are rarely observed and have a low incidence (0.4%).

Conclusion: RLNI and HPT are the most common complications of after thyroid surgery but they may be avoided with an accurate technique (Tab. 3, Ref. 15). Full Text (Free, PDF) www.bmj.sk.
