The impact of resection of a ground glass nodule on the lung depends mainly on the patient’s underlying disease, i.e., the functional reserve of the lung or the extent of resection. The left lung has 2 upper and lower lobes and includes 8 lung segments, while the right lung has 3 upper, middle and lower lobes and includes 10 lung segments. Most patients can tolerate the resection of 2 lobes or 10 lung segments or less, and the resection of lung nodules is not too extensive because the diameter is relatively small 3cm. However, if the patient is combined with emphysema or pulmonary heart disease and other conditions, the foundation of lung function is poorer in this case, and the lung will be greatly affected after resection, and the patient will experience chest tightness and shortness of breath in the near future. Single ground glass nodules can generally be surgically removed, including lung segmental resection, wedge resection or combined lung segmental resection, collectively known as sublobar resection, which has a smaller resection area and a smaller loss of lung ventilation area, so the impact on lung function after resection is smaller. Multiple pulmonary nodules have a greater impact on lung function than a single pulmonary nodule because of the larger extent of resection. It also depends on the occurrence of postoperative respiratory complications, such as pneumonia or pulmonary atelectasis in patients after surgery, which will have an impact on the patient’s lung function when recovered. Generally, patients who are able to undergo lung nodule resection are those who have been clinically screened for no special conditions after surgery, and most of them are able to recover to their normal preoperative living level.
