Transanal minimally invasive surgery (TAMIS) is a specialized minimally invasive approach to removing benign polyps and some cancerous tumors within the rectum and lower sigmoid colon. The benefit of TAMIS is that it is considered an organ-sparing procedure, and is performed entirely through the body’s natural opening, requiring no skin incisions to gain access to a polyp or tumor. This scar-free recovery provides a quick return to normal bowel function.
