观察电磁导航支气管镜引导定位后胸腔镜下肺楔形切除术对肺部磨玻璃结节的治疗效果。

回顾性分析42例肺部磨玻璃结节患者的临床资料。根据手术方式的不同分为观察组20例(电磁导航支气管镜引导定位后胸腔镜下肺楔形切除术)和对照组22例(解剖性肺段切除术)。记录两组患者的麻醉时间、手术时间、术中出血量、术后引流量、术后留置胸管引流时间、术后住院时间、术后并发症和复发情况、住院费用等数据资料，并进行比较分析。

观察组患者术中出血量、麻醉时间、手术时间、术后引流量、术后留置胸管引流时间、术后住院时间均明显少于对照组，差异有统计学意义(P<0.05)；观察组患者术后无肺漏气、血胸、气胸、肺不张等并发症出现；两组患者住院费用的差异无统计学意义(P>0.05)；随访3～24个月，两组均无复发或死亡病例，累积生存率100%。

电磁导航支气管镜引导定位后胸腔镜下肺楔形切除术是治疗肺磨玻璃结节的一种安全、有效的手术方式。手术创伤小，且不增加复发率，未降低远期生存率，亦未明显增加住院费用。

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.
