Thyroid surgery for elderly patients: Are they at increased operative risks?

Abstract

An increasing elderly population, a rising incidence of differentiated thyroid carcinoma (DTC), and a rising incidence of benign nodular disease with age are all contributing to a rise in thyroid operations for the elderly. Literature review on the outcome and safety of thyroid surgery in elderly patients has been filled with conflicting results and this subject remains controversial. Although most single-institution studies conducted by high-volume surgeons did not find significant differences of complication rates in elderly when compared with younger cohorts, they often lacked the power necessary to identify subtle differences and suffered from various selection and referral biases. Recent evidence from large population-based studies concluded that thyroid surgery in the elderly was associated with higher complication rates. One of the major contributing factors for the increased complication rate was because most elderly patients suffered from many preexisting comorbidities. Therefore, elderly patients who have abnormal thyroid findings should complete a thorough preoperative workup and better postoperative care after undergoing any thyroid surgery. Furthermore, these high-risk patients would benefit if they could be referred to high-volume, specialized surgical units early. In this systemic review, we aimed to evaluate different issues and controversies in thyroidectomy for elderly patients. © 2012 Sze-How Ng et al.
