[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.
