Eksperimentell: Betacyanin + Conventional Monitoring
All eligible patients who undergo rectal cancer resection will receive the same intervention and monitoring protocol.
Starting from postoperative day 3, each patient will orally consume 200 mL of betacyanin solution daily (concentration and formulation as specified in the study protocol).
Concurrently, pelvic drainage fluid will be collected daily to measure betacyanin concentration as a potential biomarker for early detection of anastomotic leakage.
In parallel, conventional diagnostic methods for anastomotic leakage-including clinical symptom assessment, routine laboratory tests (e.g., white blood cell count, C-reactive protein), and imaging studies when clinically indicated-will be performed on the same patients at the same time points.
Thus, each patient serves as his/her own control, allowing a direct comparison of diagnostic accuracy and healing evaluation between betacyanin-based monitoring and conventional approaches.
The intervention and monitoring will continue daily until h
