    Abstract:
    BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) segmentectomy is widely used in the field of thoracic surgery. However, anatomical variations in the bronchi and lung vessels may be critical obstacles during precise pulmonary segmentectomy. Thus, it is necessary to optimize uniportal VATS segmentectomy and to accurately identify the plane between lung segments by precisely transecting the bronchi and blood vessels of the lung segments. The indocyanine green fluorescence (ICGF)-based method has the potential to be a feasible and effective technique to facilitate the uniportal VATS segmentectomy. The present study aims at comparing the short-term outcomes of ICGF versus the traditional inflation-deflation method for uniportal VATS segmentectomy. METHODS: The perioperative clinical data in 200 consecutive patients undergoing uniportal VATS segmentectomy from December 2018 to August 2020 at Shanghai Chest Hospital were analyzed retrospectively. The targeted segment structures were identified and dissected precisely by using ICGF-based (N=100) or the traditional inflation-deflation (N=100) methods. The parameters of intraoperative blood loss and operation time, postoperative drainage volume, air leakage time, drainage tube retention time, length of hospital stay, and complications in the ICGF group were collected. Further, the operation time between the ICGF and the inflation-deflation groups was compared. The data summary and statistical analysis were performed by SPSS 19.0. P value <0.05 was considered statistically significant. RESULTS: No massive hemorrhage, hypoxemia, allergy, conversion to lobectomy, or wedge resection was noted during the surgery. ICGF groups resulted in a shorter operative time (90±11.46 vs. 118±10.59 min, P<0.001). No postoperative complications were observed, e.g., bronchopleural fistula, hemoptysis, or atelectasis. All patients were discharged as routinely scheduled. No disease recurrence or metastasis was found during the follow-ups. CONCLUSIONS: Our study indicated that the ICGF-based navigation approach is a simple, effective, and reliable technique that can greatly facilitate the uniportal VATS segmentectomy.
