Real-Time In Vivo Monitoring of Anastomotic Intestinal Ischemia Using Implantable Resorbable Organic Sensors

Area of Science:

• Biomedical Engineering
• Surgical Innovation
• Gastrointestinal Surgery

Background:

• Anastomotic failure is a critical complication in gastrointestinal surgery, leading to significant morbidity, mortality, and healthcare costs.
• Current diagnostic methods rely on late-stage systemic signs, lacking reliable early detection of local anastomotic changes.

Purpose of the Study:

• To investigate the efficacy of an intra-anastomotically placed, bioresorbable sensor for real-time bioimpedance measurements.
• To enable early detection of ischemia-related changes in gastrointestinal anastomoses.

Main Methods:

• Implantation of a novel bioresorbable sensor device directly within the anastomosis.
• Real-time intra-anastomotic bioimpedance measurements to monitor tissue health.

Main Results:

• The sensor successfully identified ischemia-related changes at an early, potentially reversible stage.
• Detection occurred prior to the onset of clinical or systemic manifestations of anastomotic failure.

Conclusions:

• Intra-anastomotic bioimpedance monitoring offers a promising method for early detection of anastomotic complications.
• The sensor technology has potential for future integration with advanced algorithms and biomarker detection.
