Core Clinical Scope: 

1. Pediatric Solid Tumors 

   - Hepatoblastoma (200+ annual surgeries)  

   - Pancreatoblastoma  

   - Wilms tumor  

   - Neuroblastoma  

2.Complex Cases

   - Tumors invading major vessels (portal vein/inferior vena cava) or with atrial tumor thrombus (>60% of cases)  

3. Recurrent/Metastatic Tumors

   - Industry-leading success rate for secondary surgeries  

Specialized Diagnostic Technologies:  

- 3D Vascular Reconstruction + Intraoperative Ultrasound: Precise tumor margin localization  

- Molecular Pathology Subtyping**: Guides individualized chemotherapy regimen design

Survival Rates Leading Internationally:  

- Hepatoblastoma postoperative 5-year event-free survival (EFS) reaches 82%, with an overall survival (OS) exceeding 90%.  

Breakthroughs in Complex Surgeries:  

- Successfully treated ultra-critical cases with tumor volumes >15 cm involving multiple liver lobes.  

Multidisciplinary Team (MDT) Collaboration:  

- Integrates 12 specialties—including surgery, oncology, and interventional radiology—to ensure optimal treatment plans.

Innovative Therapies:  

- Neoadjuvant Chemotherapy + Precision Surgery Protocol: Achieves 30%-50% tumor shrinkage, elevating resectability to 95%.  

- Autologous Vascular Grafting Technique: Overcomes major vessel invasion challenges, breaking traditional surgical boundaries.  

- Fluorescence-Guided Resection: Increases preservation of healthy liver tissue by 40%.

Surgical Expertise:  

Dr. Duan Weihong specializes in complex hepatobiliary-pancreatic and challenging surgical procedures, mastering numerous high-difficulty operations. For instance, he once led a team in performing a groundbreaking procedure for a pancreatic cancer patient: the entire pancreatic tumor, adjacent organs, and 5–6 meters of small intestine with its mesentery were resected en bloc, processed ex vivo, and then meticulously reimplanted. This cutting-edge surgery eliminated the patient's postoperative pain entirely, laying a solid foundation for subsequent chemotherapy. He has also successfully completed an extended right hemihepatectomy + complete caudate lobectomy + allogeneic vascular graft replacement of the retrohepatic inferior vena cava, with the patient achieving an excellent recovery.  

Meticulous & Patient Consultation:  

During his clinic，Professor Duan Weihong conducts thorough history-taking and physical examinations for every patient, patiently addressing all questions from patients and their families. He provides clear diagnostic and treatment plans on the spot, earning high praise from those he serves.  

Strong Sense of Responsibility:  

When treating a young patient with severe trauma—including liver rupture and massive hemorrhage from a car accident—Dr. Duan recognized the enormous surgical risks but chose to proceed, determined to save the patient's life. Post-surgery, he defied convention by remaining in the ICU to monitor the patient closely, demonstrating his unwavering commitment and responsibility.
