Dr. Dong Zhiyong

Dr. Dong Zhiyong is a board-certified surgeon specializing in minimally invasive gastrointestinal, metabolic, and hernia surgery. As Deputy Chief Physician at Jinan University’s First AƯiliated Hospital, he pioneers advanced laparoscopic techniques for obesity-related diseases, gastrointestinal tumors, and complex abdominal wall reconstruction. His seminal contribution to bariatric surgery includes developing the innovative "three-hole seven-step sleeve gastrectomy" and establishing laparoscopic sleeve gastrectomy protocols based on membrane anatomy, optimizing patient outcomes through precision and eƯiciency.

With over 10 years of clinical experience, Dr. Dong excels in:

1. Metabolic Surgery: Sleeve gastrectomy, gastric bypass, and single-anastomosis procedures for obesity, type 2 diabetes, sleep apnea, and fatty liver disease.
2. Gastrointestinal Oncology: Minimally invasive resection of gastric, colorectal, and stromal tumors.
3. Hernia Repair: Laparoscopic management of inguinal, femoral, incisional, umbilical, hiatal, and parastomal hernias.
4. General Surgery Emergencies: Acute abdominal conditions (perforations, obstructions, appendicitis), saphenous vein disorders, axillary odor, and anorectal diseases.

Trained as a Visiting Scholar at Northwestern University (USA) and holding a Doctorate in Medicine from Jinan University, Dr. Dong bridges clinical practice with rigorous research. His focus spans:

• Refining minimally invasive techniques for metabolic disorders.
• Advancing evidence-based protocols for gastrointestinal cancer surgery.
• Optimizing hernia repair durability through anatomical precision. He actively translates research into practice as a Reviewer for Obesity Surgery, Young Editorial Board Member of the Chinese Journal of General Surgery, and Secretary General of the Obesity and Metabolic Surgery Committee (Guangdong Medical Association).
