Effects of preserving the bronchial artery on cough after thoracoscopic lobectomy.

Abstract

BackgroundThe purpose of this prospective study was to explore the influence of both preoperative three‐dimensional (3D) reconstruction and intraoperative preservation of the bronchial artery (BA) on postoperative cough after thoracoscopic lobectomy.MethodsA total of 60 patients who had received a combination of thoracoscopic lobectomy and systematic lymph node dissection were included in this study. They were divided into two groups, namely the BA preservation group (Group A), and conventional surgical treatment group (Group B). In group A, we used Exoview software for 3D reconstruction of the BA before the operation and the BA was preserved during the operation. 3D reconstruction of the BA was not performed before surgery in group B. The incidence of postoperative cough, the Mandarin Chinese version of the Leicester cough questionnaire (LCQ‐MC), physiological, psychological and social dimensions and total score of the two groups were compared and analyzed.ResultsThe scores and total scores of LCQ‐MC in group B were lower than those in group A one and two months after surgery. There were significant differences between the two groups in physiological and psychological dimensions and total scores (p < 0.05), but there was no significant difference in social dimension between the two groups (p > 0.05). The incidence of postoperative cough in group A (16.7%) was lower than that in group B (30%), while the difference was not statistically significant (p = 0.222).ConclusionsPreoperative 3D reconstruction and intraoperative preservation of the BA can reduce the severity of postoperative cough.
