A Study to Validate the Safety and Feasibility of ArtiSential in Colorectal Cancer Surgery Using Prospectively Constructed Multi-center Registry

This study is evaluating the safety and practicality of using a surgical robotic tool called ArtiSential during colorectal cancer operations. ArtiSential is an articulating laparoscopic instrument — a flexible tool used in minimally invasive surgery — and this study will track whether it is safe and feasible across multiple surgical centers. **You may be eligible if...** - You are between 18 and 80 years old - You have been diagnosed with rectal cancer or rectosigmoid junction cancer confirmed by biopsy - It is your first (primary) cancer, without distant spread - You are scheduled for elective (planned, non-emergency) surgery with curative intent - The surgical plan includes a low anterior resection using a double-stapled technique **You may NOT be eligible if...** - You are receiving systemic (full-body) chemotherapy before surgery - Your cancer has spread to distant organs (metastatic) - Surgery is palliative (not aiming for cure) - Your surgery is an emergency - You have Lynch syndrome or familial adenomatous polyposis (FAP)-related cancer Talk to your doctor to see if this trial is right for you.
