Pdf Summary

The document presents a study conducted to evaluate a new method for detecting air leaks during video-assisted thoracoscopic surgery. Traditionally, the submersion sealing test has been used as the gold standard for this purpose, but it has limitations, such as affecting surgical visibility and not allowing continuous monitoring during repair.<br /><br />The study focuses on using Indocyanine Green (ICG) inhalation combined with near-infrared fluorescence to identify air leak sites in a more effective and efficient manner. The method was tested on five patients who underwent lung resection. Following this procedure, a mesh nebulizer facilitated the inhalation of ICG at a concentration of 3.75 mg/ml. Detection of air leak sites was subsequently performed using near-infrared fluorescence, with validation through the submersion sealing test.<br /><br />The results demonstrated that out of 20 identified fluorescent air leak sites, 17 (85%) were confirmed to be true air leaks. The process of detection using near-infrared fluorescence took an average of 15.8 seconds, allowing for continuous imaging throughout the surgery. There were no complications from ICG inhalation, although two patients experienced postoperative air leaks that were resolved through conservative treatment.<br /><br />In conclusion, ICG inhalation combined with near-infrared fluorescence offers a convenient, simple, and effective method for intraoperative detection of air leak sites during thoracoscopic surgery. This technique allows for more accurate identification without disrupting surgical exposure, potentially improving patient outcomes by reducing the occurrence of missed air leak sites.
