The length of time required for a surgical procedure for lung nodules usually depends on whether the nodule is benign or malignant, so the length of time cannot be generalized. 1. Benign nodules (1) If the nodule is benign and in a good position, it can usually be removed by excision or wedge resection, and if the operation goes well, it can usually be finished in about one hour. (2) If the lung nodule is benign, but the location is deeper, in order to retain more normal lung tissue, the lung segmental resection is used, because the lung segmental resection requires higher anatomical requirements, the operation is difficult, and usually takes about 2 hours. 2. Malignant nodule: If the lung nodule is malignant and requires further resection of the lung lobes, the whole lung, etc., and lymph nodes need to be cleared, the operation is usually more complicated and difficult, and usually takes 2-3 hours to complete; if the nodule is located in the vicinity of the blood vessels and nerve tissues, then the operation time may be relatively longer. If the nodes are located near blood vessels and nerve tissues, the operation may take longer. The exact length of the operation depends on the nature of the nodes, the doctor’s skill, and the degree of difficulty of the operation, so if you feel unwell, consult a specialist for guidance.
