This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
During bowel surgery, surgeons need to check that the reconnected tissue has adequate blood flow to heal properly. This trial compares two imaging techniques that do this: one uses a camera-based system called imaging photoplethysmography (iPPG) that detects blood flow changes without injecting dye, and the other uses the standard method called indocyanine green (ICG) fluorescence imaging, which involves injecting a special dye to visualize blood flow. The study will help determine which method works better to guide surgeons' decisions during surgery.
After bowel surgery, poor blood flow to the reconnected tissue is a serious complication that can lead to infection and other problems. The new camera-based imaging method may offer surgeons a safer, simpler way to assess blood flow during surgery without needing to inject dye, but researchers need to compare it directly to the current standard method to see if it works just as well.

If you qualify, you will be randomly assigned to receive one of two imaging methods during your scheduled bowel surgery. One group will have their tissue blood flow assessed using the new camera-based imaging system (iPPG), while the other group will receive the standard fluorescence imaging with dye injection (ICG). The imaging happens during your surgery as part of the procedure — you won't need extra visits or recovery time beyond normal bowel surgery recovery. Surgeons will use the imaging results to guide their surgical decisions, and researchers will compare how well each method worked.
