Factors influencing thyroidectomy complications

Abstract

The postoperative outcome of thyroidectomies is related to factors concerning the patient, the thyroid disease, and the surgeon. ObjectivesTo analyze a clinic's experience with thyroidectomy complications. Study design: historical cross-sectional cohort study. Materials and MethodsWe reviewed the charts from 228 patients submitted to thyroidectomy, between 1991 and 2004. Transient, permanent and total complications as well as persistence and recurrence of the basal disease were studied in relation to clinical and laboratory factors. ResultsTotal complications occurred in 34.65%, transient complications in 18.86% (9.21% had hypocalcemia, 0.44% had vocal cord paralysis), associated with the first postoperative years and pressure complaints, and permanent complications in 17.98% (8.77%: hypoparathyroidism; 1.75%: vocal cord paralysis), associated with malignancy and more radical surgeries. The thyroid disease persisted in 17.98% of the cases, associated with age and recurrence in 10.96%, associated with the first operative years, benign diseases and less radical surgeries. ConclusionThe complications were associated with pressure complaints, shorter complaining period, malignancy and more radical surgeries. The recurrence was associated with the first operative years, non-neoplastic thyroid diseases and less radical surgeries. The persistence of disease was associated with older age.
