Abstract:
Objective To analyze the feasibility, advantages and disadvantages of the fluorescence method and the inflation-deflation method in defining the intersegmental plane during thoracoscopic lung segmental resection. Methods From February to October 2018, 60 patients underwent thoracoscopic anatomical segmentectomy in Thoracic Surgery Department of Nanjing Chest Hospital, with 28 males and 32 females, aged from 25 to 82 years. Three-dimension computed tomography bronchography and angiography was used to reconstruct pulmonary vessels, bronchus and virtual intersegmental plane. Among them, 20 patients used the fluorescence method to define the intersegmental plane, and the other 40 patients used the traditional inflation-deflation method to define the intersegmental plane. Results Fluorescent injection of indocyanine green (ICG) showed a clear intersegmental line with a duration sufficient to complete the label. With the fluorescence method, the intersegmental plane occurrence time was significantly shortened (10.75±3.78 s vs. 988.00±314.24 s, P<0.001) and had satisfactory repeatability. The lungs did not need to be inflated, which was convenient for the operation. And the operation time was shortened (108.75±31.28 min vs 138.00±32.47 min, P=0.002). No obvious ICG injection-related concurrency symptoms was found. Conclusion Compared with the traditional inflation-deflation method, the fluorescence method can display the intersegmental line quickly, accurately and clearly, reduce the difficulty of surgery, shorten the operation time, and provide reliable technical support for thoracoscopic anatomical segmentectomy. The fluorescence is a safe and effective method that is worthy of clinical application.
