Thoracoscopic combined subsegmentectomy for 76 patients: A retrospective study in a single center / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To summarize the clinical experience of thoracoscopic combined subsegmentectomy (CSS). Methods    The clinical data of 76 patients who underwent thoracoscopic CSS in Anqing Municipal Hospital from May 2018 to July 2022 were retrospectively analyzed, including 22 males and 54 females, aged 27.0-76.0 (54.3±10.5) years. All patients underwent preoperative three-dimensional computed tomography bronchography and angiography using dual source CT. The modified inflation-deflation technique or indocyanine green was used to identify the intersubsegmental border. Results    A total of 86 pulmonary nodules were resected in 76 patients. One patient of left upper lobe S1+2c+S4a, 1 patient of right upper lobe S2b+S3a and 1 patient of right upper lobe S1b+S3b were further performed lobectomy due to insufficient margin. One patient of left upper lobe S1+2+S3a was further performed left upper division segmentectomy due to residual atelectasis. One patient of left upper lobe S1+2c+S3a was further performed left upper division segmentectomy due to B3b+c injury, and the rest completed planned surgeries successfully. The operative time was 90.0-350.0 (174.9±53.2) min. The operative hemorrhage volume was 50.0 (20.0, 50.0) mL. The postoperative hospital stay time was 6.0 (5.0, 7.0) d. Postoperative complications included pulmonary infection in 9 patients, hemoptysis in 3 patients, persistent pulmonary leakage>3 d in 4 patients, pneumothorax in 1 patient, pleural effusion in 1 patient, and myocardial infarction in 1 patient. All of the patients were cured and discharged without perioperative death. Conclusion    Thoracoscopic CSS is relatively complex. Preoperative planning under three-dimensional reconstruction and intraoperative fine operation are helpful for safe completion.
