Objective:
To conduct a narrative review of the current anatomical interpretation of the right hemicolon fascial system and present the author's understanding.
Key Findings:
- Total mesorectal excision (TME) and complete mesocolic excision (CME) significantly improve survival rates in colorectal cancer.
- Controversies exist regarding the abdominal fascial system and surgical planes in right colon cancer surgery.
- Terminological inconsistencies hinder academic communication in the understanding of the right colon fascia.
Interpretation:
Despite non-uniform terminology, the concept of fusion space is deemed most useful in surgical practice with histological justification.
Limitations:
- Terminological confusion persists in the literature.
- The review may not encompass all recent advancements in surgical techniques.
Conclusion:
A systematic understanding of the right hemicolon fascial system is essential for precise surgical interventions in colorectal cancer.
