TAMIS and Scarless Surgery
Transanal Minimally Invasive Surgery (TAMIS) has matured in 2026 as the preferred method for removing large polyps and early-stage cancers in the rectum. By using a specialized gel port inserted through the natural orifice (the anus), surgeons can perform complex dissections inside the rectum using standard laparoscopic or robotic tools. This eliminates the need for any abdominal incisions.
Because there is no "entry trauma" to the abdominal wall, TAMIS patients often experience almost no postoperative pain and can return to work within days. In 2026, this technique is increasingly paired with AI-enhanced endoscopy, where computer algorithms help the surgeon identify the exact boundaries of a lesion in real-time, ensuring "clear margins" while preserving as much healthy tissue as possible.
