New precision surgery aims to save more rectal cancer Patients' bowel function

This study tests a new surgical technique called Q-ISR for people with ultra-low rectal cancer. It compares Q-ISR to two standard surgeries to see if it can better preserve bowel function while still controlling the cancer. About 100 adults with small tumors near the anal opening will take part. The goal is to find a smarter way to remove the cancer without harming quality of life.
