Pathological puncture biopsy is the key to early diagnosis and treatment of thoracic tumours,and percutaneous puncture biopsy(PTNB)technology has been widely used in clinical practice.Common complications of PTNB include pneumothorax,air embolism and pulmonary hemorrhage.In order to optimize traditional PTNB,our center has developed a new percutaneous puncture diagnosis and ablation technology for lung lesions,which greatly reduces the occurrence of complications,increases the accuracy of pathological biopsy.At the same time,it can bridge target lesion ablation.This article describes the standard operating procedure for diagnosis and ablation techniques of filling operation assisted percutaneous transthoracic needle biopsy under rigid endoscopy with regular frequency controlled ventilation during general anesthesia.
