Objective:

To systematically review the current status and effectiveness of various biomarkers in predicting anastomotic leakage (AL) after colorectal surgery and propose a comprehensive multimodal prediction framework.

Key Findings:
  • Anastomotic leakage has an incidence of 2% to 19% and is associated with significant complications.
  • Traditional diagnostic methods are reactive and often delayed, increasing adverse outcomes.
  • Biomarkers from inflammation, ischemia, microbiome, and tissue repair show potential for early detection of AL.
  • Machine learning algorithms may help integrate diverse data sources, but external validation is lacking.
Interpretation:

The review highlights the fragmentation in existing research on biomarkers for AL, indicating a lack of systematic integration of findings into clinical tools.

Limitations:
  • Existing studies are heterogeneous in endpoints, timing, and methodology, with examples including variations in biomarker types and measurement techniques.
  • Most research is based on small-sample, single-center cohorts with limited external validation.
Conclusion:

A multimodal prediction framework integrating inflammation, ischemia, microbiome, and tissue repair is proposed, emphasizing the urgent need for future research focused on validation and standardization.
