To analyze the treatment of pulmonary ground-glass nodules (GGN) through thoracoscopic wedge resection under the guidance of electromagnetic navigation bronchoscopy (ENB).

The clinical data of 42 patients with GGN were retrospectively analyzed. According to different treatment methods, patients were divided into observation group (thoracotomy pulmonary wedge resection after electromagnetic navigation bronchoscopy guided positioning) and control group (anatomical segmental resection), with 22 in observation group and 20 in control group. Anaesthesia time, surgical time, intraoperative bleeding volume, postoperative drainage volume, postoperative indwelling chest tube drainage time, postoperative hospitalization time, postoperative complications and recurrence, and hospitalization costs were analyzed in the two groups of patients, and electromagnetic navigation bronchoscopy was evaluated. Effect of thoracoscopy pulmonary wedge resection after guided localization on ground glass nodules in the lung.

The blood loss, anesthesia time, operation time, postoperative drainage, postoperative indwelling chest drainage, and postoperative hospital stay were significantly lower in the observation group than in the control group (P<0.05). A comparative analysis of postoperative complications between the two groups of patients suggests that the observation group is less than the control group. There was no significant difference in hospitalization costs between the two groups of patients, with no statistical significance (P>0.05). The follow-up time was 3 to 24 months, and no patients died.

Electromagnetic navigation bronchoscopy guided wedge resection of the ground glass nodules can reduce intraoperative bleeding and postoperative drainage, shorten the time of indwelling the chest tube, speed up the discharge of patients, and reduce surgical trauma without increasing relapse rate, which does not reduce long-term survival rate or increase hospitalization costs significantly, is a safe and effective treatment.
