Value of endobronchial ultrasound-guided localization with combination of ultrathin bronchoscope and methylene blue for small pulmonary nodules before video-assisted thoracoscopic surgery / 中华胸心血管外科杂志

ABSTRACT

Objective To analyze the value of endobronchial ultrasound-guided ultrathin bronchoscope(EUGUB) and methylene blue positioning video-assisted thoracoscopic surgery(VATS) for small pulmonary nodules.Methods Sixty patients undergoing VATS, using pre-operative EUGUB combination with methylene blue was performed .The positioning accuracy, the complications and pathological classification were analyzed .Results EUGUB combination with methylene blue positioning ac-curacy was 91.7%, meanwhile, 2 patients with hemoptysis with no conservative treatment.The postoperative histological pa-thology results showed that benign lesions and malignant lesions accounted for 28.3% and 71.7%, respectively.Conclusion The method of EUGUB combination with methylene blue in positioning of the small pulmonary nodules increases the achieve-ment ratio of VATS with few complications, and may be widely used in treatment of small pulmonary nodules with VATS.
