This study looks at surgery for colorectal cancer, which affects the colon or rectum. Researchers want to learn more about using technology like **computer vision (CV)** and **artificial intelligence (AI)** with an **infrared fluorescence agent (IFA)** during surgery. These tools may help doctors understand tissue health by showing how a special dye flows in the body. The dye is safe and already approved for this kind of study. - 🗓 **Time Commitment**: The study will take place over three years, with a follow-up 30 days after joining. - 🏥 **Visits**: Participants might undergo surgery and have follow-up visits. The study involves observing the dye during surgery and collecting tissue samples. - 👥 **Eligibility**: Adults 18+, with colorectal issues needing surgery, no allergy to the dye, and women must have a negative pregnancy test. This study does not involve any new surgeries or treatments, just the use of advanced technology to gather information. Participants must be willing to give consent and follow study requirements. Those with certain health conditions may not qualify.
