    Abstract:
    PURPOSE: We aimed to assess the clinical usefulness of the fissureless technique, which avoided dissection of the lung parenchyma over the pulmonary artery, in preventing prolonged air leak after video-assisted thoracic surgery right upper lobectomy (VATS RUL). METHODS: Perioperative outcomes, including the frequency of prolonged air leak after fissureless technique or traditional fissure dissection technique, which dissected the lung parenchyma through the fissure, were compared in patients who underwent VATS RUL (n = 213) between January 2016 and March 2020. We adopted our fissural grade to evaluate the degree of fused fissure ranging from II (light incomplete fissure) to IV (severe incomplete fissure), which covered all fissural grades in 213 patients. RESULTS: Fifty-four and 159 patients underwent fissureless and traditional techniques, respectively. Significant differences in the incidence of prolonged air leak (p = 0.037), time to air leak cessation (p = 0.047), and duration of chest tube placement (p = 0.017) were observed between fissureless and traditional technique groups. On multivariable analysis, traditional technique (p = 0.005), and greater fissural grade (III vs II, p = 0.020; IV vs II, p = 0.001) were significantly associated with prolonged air leak. CONCLUSIONS: Fissureless technique during VATS RUL can be a superior alternative to the traditional technique to prevent prolonged air leak in treating incomplete fissures.
