Abstract
BackgroundThe prevalence of potential risk factors for postoperative cough after thyroidectomy remain unknown. The current study aimed to research postoperative cough in patients undergoing thyroid surgery prospectively.MethodsAdult patients who underwent primary thyroid surgery were selected prospectively. Data regarding age, sex, BMI, pathology and surgical procedure were collected and analyzed. The Leicester Cugh Questionnaire (LCQ) was required to be completed by all patients before operation, 2 weeks and 4 weeks after operation.ResultsThere were 1264 patients enrolled in total. Eleven patients with vocal cord paralysis were excluded. In patients with benign disease, postoperative cough occurred in 61 patients, with an prevalence rate of 17. 0% compared to an prevalence rate of 33.1% in patients with malignant disease; the difference was significant. For benign patients, the factors of smoking and operation time were independently related to the occurrence of postoperative cough. For malignant patients, the factors of smoking, operation time, operation extent, and the number of positive nodes at level 6 were independently related to the occurrence of postoperative cough. There was no significant difference regarding the LCQ score in patients with benign or malignant disease at the preoperative and the postoperative 4-week time periods. Patients with malignant disease had a significantly lower LCQ score than patients with benign disease at the postoperative 2-week time point (p = 0.004).ConclusionsPatients undergoing thyroid cancer surgery had a higher incidence of postoperative cough and were also associated with a decreased cough-related quality of life. The factors of smoking and operation time were the most important predictors for postoperative cough after thyroidectomy.
Highlights
The prevalence of potential risk factors for postoperative cough after thyroidectomy remain unknown
Wu et al BMC Cancer (2020) 20:888 including smoking history, surgical extent, and operation time might be associated with postoperative cough
The exclusion criteria were as follows: the patient had chronic cough associated with smoking or gastroesophageal reflux or with other causes; resection of the trachea or larynx was performed; the recurrent laryngeal nerve was invaded by the tumor or metastatic nodes resulting in recurrent laryngeal nerve paralysis; and there was pulmonary infection
Summary
The prevalence of potential risk factors for postoperative cough after thyroidectomy remain unknown. The current study aimed to research postoperative cough in patients undergoing thyroid surgery prospectively. There has been a substantial increase in the proportion of thyroid cancer cases globally, on the one hand, because the prevalence has really increased, on the other hand, because of the prevalence of thyroid color Doppler ultrasound examination [1]. Wu et al BMC Cancer (2020) 20:888 including smoking history, surgical extent, and operation time might be associated with postoperative cough. There are few studies available in terms of its prevalence and potential predictors. Our goal was to prospectively analyze the postoperative cough in patients who undergoing thyroidectomy
