Abstract: This paper explored the comparative analysis of Indocyanine Green (ICG) fluorescence staining and modified inflation-deflation method in thoracoscopic pulmonary segmentectomy. Selected 75 patients with lung cancer who received thoracoscopic pulmonary segmentectomy, then randomly divided them into the control group with 35 cases and the study group with 40 cases according to the digital table method. The control group used the modified inflation-deflation method and the study group used the Indocyanine Green (ICG) fluorescence staining method. Compared the efficacy, operation-related indicators of the two groups, and detected the conventional lung ventilation function test. Compared with the control group, the drainage time, chest drainage flow, hospital stay, peak expiratory flow (PEF), forced expiratory volume in one second (FEV1) and forced expiratory volume (FVC) of patients in the study group were all decreased (P<0.05). Patients in study group had earlier formation time of intersegment plane and shorter operation time than those in the control group (P<0.05). The overall incidence of complications in the control group (25.71%) was higher than that in the study group (7.50%), and the difference was statistically significant (P<0.05). Both the ICG fluorescence staining method and the modified inflation-deflation method can affect the lung function of patients during thoracoscopic pulmonary segmentectomy, while the ICG fluorescence staining method has less impact on the lung function, and the incidence of complications is also lower, which can be highly accurate identify the junction line between segments, with high security.
