A new method for minimally invasive treatment of small pulmonary nodules–CT-guided microspring circle positioning thoracoscopic resection of small pulmonary nodules In recent years, with the strengthening of public health care awareness, small pulmonary nodules are increasingly diagnosed, and the development of thoracoscopic minimally invasive technology has enabled patients to avoid many more invasive open-heart surgeries, and thoracoscopy is increasingly accepted by patients and The development of minimally invasive thoracoscopic techniques has enabled patients to avoid many more invasive open-heart surgeries, and thoracoscopy is increasingly accepted by patients and healthcare professionals. However, for small nodules smaller than 1 cm, they have to be converted to open-heart surgery because they are difficult to find during thoracoscopic surgery. This has led many doctors to design many preoperative or intraoperative localization methods. However, this method is not suitable for small superficial nodules. The CT-guided microspring circle localization method adopted by our department and the Department of Radiology can avoid this deficiency, and at the same time, its operation is easy and fast, and its localization is accurate and direct, so it is suitable for even very small and deeply located pulmonary nodules. The costs associated with avoiding intermediate openings, reducing surgical exploration time and damage to the lung are also reduced. The day before surgery, CT-guided microspring coil localization is performed under local anesthesia, and the tail wire of the microspring coil is left adjacent to the lesion. During surgery, the tail wire is easily found under thoracoscopy, and the 2-3 cm of lung tissue around the tail wire is directly removed without the need to do lesion finding and repeated exploration, and the surgery takes only 20-35 minutes. He was discharged from the hospital 5-8 days after 6 hours of postoperative feeding. Among the surgical cases that Dr. Gao Zhi has completed in our department, 20% were benign nodules, 20% were precancerous lesions (adenomatous hyperplasia), and the rest were lung cancers, one of which had been accompanied by mediastinal lymph node metastasis (middle to late stage), so early thoracoscopic surgery should be considered for nodules of 8-30 mm found on physical examination and nodules less than 8 mm that are highly suspected of malignancy after clinical examination.
