Leakage Rate of Ileo-COlic Sutured Anastomosis After Right Hemicolectomy

This study is collecting data on a specific type of bowel reconnection surgery (ileo-colic anastomosis) performed after removing the right side of the colon — typically for colon cancer. Researchers want to understand the rate of leaks at the reconnection site when hand-sewn sutures are used. **You may be eligible if...** - You are 18 or older - You are having elective (planned, not emergency) right-sided colon removal surgery for cancer - Your surgeon plans to reconnect the bowel using hand-sewn or a combination of sewn and stapled technique - Your cancer has not spread to the lining of the abdomen or nearby structures - You have signed a data protection and consent form **You may NOT be eligible if...** - You are having left-sided colon or rectal surgery - You are having emergency surgery - Your cancer has spread to the peritoneum (abdominal lining) or nearby blood vessels or nerves - You are under 18 Talk to your doctor to see if this trial is right for you.
