Dr. Weiguang Long serves as Vice President of the Institute of Chest Wall Surgery (ICWS), and Executive Committee Member and Secretary-General of the Chest Wall Surgery Specialty Committee under the Guangdong Association of Thoracic Diseases.

With over a decade of experience in clinical practice, scientific research, and education in chest wall surgery, Dr. Long has made significant contributions, particularly in the field of chylous diseases. He has refined techniques for chemical pleurodesis and pericardial window, successfully treating over 200 complex cases and achieving a 100% cure rate for congenital chylothorax. Remarkably, no subsequent complications have been observed in children with congenital chylothorax after treatment, and their physical and intellectual development proceeds normally.

Dr. Long pioneered the concept of "promoting the reconstruction and recanalization of chest wall lymphatic circulation" after extensive research into the structure and function of lymphatic system. This innovative approach has set a new benchmark in the minimally invasive treatment of chylothorax. He has led and contributed to 6 provincial and municipal research projects, published over 10 academic papers including 4 SCI-indexed articles, and holds 6 national patents.
