[Treatment principle and surgical technique of pulmonary ground glass nodules].

Pulmonary ground glass nodule (GGN) is a term of radiological manifestation, which may be malignant or benign. GGN's imaging performance is diverse, and the management for pulmonary GGN remains controversial. Numerous clinical studies have clarified the safety of GGN follow-up and longer follow-up intervals, stricter surgical or biopsy indications are recommended. In clinical practice, the size of GGN, the size of consolidation, dynamic change during follow-up are the factors that help surgeons to decide the timing of surgery. There are some misunderstandings for the management of GGN, such as the administration of antibiotics, the use of PET-CT, pure GGN adjacent to visceral pleura, and GGN with penetrating vessel. Segmentectomy for ground glass nodules is being accepted by more and more surgeons. Through theoretical study and clinical practice, surgeons can master anatomical segmentectomy.肺部磨玻璃结节(GGN)是一种影像学表现，可能是肺部恶性肿瘤或良性病变。GGN的影像学表现多样，目前对于肺部GGN的诊疗仍存在争议。大量临床研究明确了GGN随访的安全性，并提出更长的随访间隔时间和更严的手术或活检指征。在临床工作中，GGN的大小、实性成分大小和动态随访变化均为判断手术介入时机的因素。GGN的诊疗中还存在一些误区，如抗生素的使用、PET－CT检查、贴近胸膜的纯GGN和进入GGN的血管均是值得注意的问题。GGN的肺段切除正在被越来越多的医师接受，通过理论学习和经验积累，外科医师能很好地掌握解剖性肺段切除。.
