Objective:
To determine the 3-year disease-free survival (DFS) and overall survival (OS) outcomes of the mixed approach vs. the medial approach in laparoscopic right hemicolectomy.
Key Findings:
- No significant difference in DFS (HR = 1.799, p > 0.05) and OS (HR = 1.274, p > 0.05) between medial and mixed approach groups.
- Tumor location and chemotherapy completion were identified as independent prognostic factors for DFS.
Interpretation:
Both surgical approaches yielded similar long-term oncological outcomes, suggesting the mixed approach is a viable alternative.
Limitations:
- Retrospective design may introduce selection bias.
- Censoring rate of 10% could affect survival analysis.
Conclusion:
The mixed approach may be preferred due to its safety and efficacy, with comparable 3-year DFS and OS rates to the medial approach.
