ABSTRACT
@#Objective To summarize our experience of surgical resection of multiple ground-glass opacity (GGO) in recent years. Methods Clinical data of patients who underwent one-stage resections of multiple GGO from November 2015 to May 2019 in our hospital were collected, including 13 males and 52 females at an average age of 56.0±9.4 years. The clinical effects and pathological types of GGO were evaluated. Results Time interval from first discovery to surgery was 8-1 447 (236.5±362.4) days. There were 48 patients with unilateral surgery and 17 patients with bilateral surgery during the same period. Except for 2 patients who underwent open thoracotomy due to total thoracic adhesions, other patients underwent video-assisted thoracoscopic surgery (VATS). The mean postoperative hospital stay was 12.2±4.3 days. No severe perioperative complication or death occurred. A total of 156 GGO lesions were resected, 80 lesions were pure GGO, including 58 (72.5%) malignant lesions and 22 (27.5%) benign lesions, with an average diameter of 7.7±3.3 mm and 5.5±2.6 mm, respectively. Another 76 lesions were mixed GGO, including 69 (90.8%) malignant lesions and 7 (9.2%) benign lesions, with an average diameter of 13.6±6.6 mm and 7.7±3.5 mm, respectively. Conclusion Patients with multiple GGO should be treated with anti-inflammatory therapy firstly. When conservative treatment is ineffective and no benign outcomes are observed, surgical treatment should be considered. And when lung function is sufficient for patients to underwent surgeries, the simultaneous unilateral or bilateral thoracoscopic resection is suggested, and the sublobar resection or lobectomy methods can be adopted flexibly according to the clinical features of the lesion and the rapid pathological results, which will not increase the risk of postoperative complications. Otherwise, surgical resection should be given priority for pure GGO lesions with a diameter > 7.7 mm and mixed GGO lesions.
