Objective:

To examine current and emerging technologies for assessing postoperative recurrence in Crohn's disease, highlighting the challenges in monitoring.

Key Findings:

• Composite strategies combining biomarkers with imaging are more robust than single-measure approaches.
• Advanced imaging techniques can detect subtle changes preceding macroscopic recurrence.
• Intestinal ultrasound shows strong correlation with endoscopic recurrence, especially when combined with fecal calprotectin.
• AI-enabled integration of data could standardize assessments and improve precision in monitoring.

Interpretation:

Combining advanced imaging with AI and multi-omics data may enhance postoperative surveillance, allowing for proactive monitoring and earlier interventions.

Limitations:

• Current monitoring tools have variability in reliability and require further validation, particularly in distinguishing postsurgical changes from early inflammatory recurrence.
• Standardization of imaging techniques is necessary for consistent application.

Conclusion:

The integration of advanced technologies could improve long-term outcomes in Crohn's disease by personalizing monitoring strategies, but requires prospective validation.
