"Sun's Seven-Step Technique" for Endoscopic En-Bloc Resection of Thyroid Cancer via the Chest-Breast Approach
November 28th, 2025
Endoscopic en bloc resection for thyroid carcinoma presents significant technical challenges, with current literature lacking comprehensive methodological descriptions. A systematic development and description of the "Sun's Seven-Step Technique" for endoscopic en-bloc thyroidectomy via the chest-breast approach was presented, demonstrating its superior operative efficiency, safety, and clinical feasibility.
Overview
This article presents a systematic protocol for endoscopic en-bloc resection in thyroid cancer surgery, known as "Sun's Seven-Step Technique." The method addresses technical challenges associated with endoscopic en-bloc resection and aims to improve both oncological radicality and cosmetic outcomes. Comparative analysis demonstrates that this technique maintains surgical safety and efficacy while reducing operative time.
Key Study Components
Area of Science
- Surgical oncology
- Endoscopic surgery
- Thyroid cancer treatment
Background
- Endoscopic thyroid cancer surgery via the chest-breast approach is established for its oncological and cosmetic benefits.
- The en-bloc resection concept is increasingly applied in radical thyroidectomy.
- Technical challenges and lack of detailed protocols have limited widespread adoption of endoscopic en-bloc resection.
- Optimized surgical techniques are needed to enhance outcomes and procedural efficiency.
Purpose of Study
- To develop and describe a systematic endoscopic en-bloc resection protocol for thyroid cancer.
- To compare the new technique with conventional resection methods regarding safety, efficacy, and operative time.
- To provide a reference protocol for surgeons performing endoscopic thyroidectomy.
Methods Used
- Development of "Sun's Seven-Step Technique" for endoscopic en-bloc resection.
- Incorporation of optimized surgical plane selection and modified operative sequences.
- Use of a specialized lymphatic tracer injection method.
- Comparative analysis with conventional resection (lobectomy plus separate lymph node dissection).
Main Results
- No significant differences in blood loss, lymph node dissection efficacy, or surgical complications between groups.
- En-bloc resection group achieved significantly shorter operative times.
- Technique improved compliance with oncological radicality principles.
- Facilitated identification of accidentally resected inferior parathyroid glands and improved exposure of lower-level lymph nodes.
Conclusions
- "Sun's Seven-Step Technique" is a safe and efficient protocol for endoscopic en-bloc thyroid cancer resection.
- It maintains oncological and cosmetic outcomes while reducing operative time.
- The protocol serves as a valuable reference for endoscopic thyroid surgery.
