To analyze the role of three-dimensional reconstruction guided thoracoscopic segmentectomy in the diagnosis and treatment of ground glass nodules (GGN).

The clinical data of nine patients with GGN who underwent three-dimensional reconstruction guided thoracoscopic segmentectomy at the Peking University International Hospital from October 2020 to June 2021 were retrospectively analyzed.

All the nine patients successfully underwent three-dimensional reconstruction guided thoracoscopic segmentectomy. The nodules were located in the right superior lobe in two patients, in the right inferior lobe in one patient, in the left superior lobe in five patients, and in the left inferior lobe in one patient. There was no conversion to thoracotomy, and the rate of R0 resection was 100% (9/9). The operation time was (377.89±115.96) min, and the intra-operative bleeding loss was (150.00±96.82) ml. The duration of postoperative drainage was (6.33±2.39) d, the total amount of postoperative thoracic drainage was (1 278.89±511.23) ml, and the duration of postoperative hospitalization was (8.78±2.68) d. There was one (11.11%) patient whose postoperative thoracic drainage time was >7 d, and the main cause of delayed extubation was prolonged lung air leakage. All the nine patients had postoperative complications, including four with grade 1 complications and five with grade 2 complications; no grades 3-5 complications or perioperative death occurred. The number of groups of dissected lymph nodes was 3-6 [(4.89±1.05)], and the total number of dissected lymph nodes was 11-20 [(14.00±2.73)].

Three-dimensional reconstruction guided thoracoscopic segmentectomy is safe and effective in the diagnosis and treatment of GGN.
