Surgical complications after thyroid surgery performed in a cancer hospital.

OBJECTIVE

This study evaluates the incidence and risk factors of complications in patients submitted to thyroidectomy in a cancer hospital with residency training.

STUDY DESIGN

A retrospective chart and complications review of 1020 patients (1990-2000) underwent to thyroidectomy.

RESULTS

At our cancer hospital, 1020 patients underwent thyroidectomy. The main postoperative complications consisted of transient hypocalcemia in 134 (13.1%) patients, permanent hypocalcemia in 26 (2.5%) patients, transient vocal cord palsy in 14 (1.4%) patients, and permanent vocal cord palsy in 4 (0.4%) patients. The type of thyroidectomy, neck dissection, and paratracheal lymph node dissection were significantly associated with transitory and permanent hypocalcemia.

CONCLUSION

Thyroid surgery can be performed safely in a surgical residency training program under direct supervision of an experienced surgeon with little morbidity to the patients. Hypocalcemia is the most significant complication. Neck and paratracheal lymph node dissections were the most significant predictors of hypocalcemia in patients who underwent total thyroidectomy.
