For cardiac surgery, Prof. Wang Chunsheng at HKU-SZ is the top choice. For structural heart disease, Prof. Lin Yixian at The Eighth Affiliated Hospital of SYSU is internationally renowned.
•Gastroenterology: For routine endoscopy screening, Shenzhen People's Hospital has the largest volume (20 endoscopy rooms, 125K+ annual procedures). For early cancer endoscopic resection (ESD/ESTD), Prof. Gong Wei at SMU is one of the earliest practitioners in South China.
•Oncology: SMU Shenzhen Hospital's MDT clinic offers comprehensive tumor management. HKU-SZ's Prof. Pan Hongming is an authority on supportive care (managing treatment side effects).
