Transanal Approaches: Transanal Minimally Invasive Surgery (TAMIS)
Following the popularization of colorectal cancer screening, the incidence of large rectal polyps and early-stage cancer is increasing . Due to the suboptimal functional outcomes following proctectomy, an aging population, stoma aversion, and improving response rates following neoadjuvant chemoradiation, local excision of large polyp early-stage rectal cancer is increasingly being requested by patients and utilized in clinical practice . The modalities available for the local excision of both large polyps and early-stage rectal cancers include traditional transanal excision (TAE), colonoscopic/endoscopic mucosal resection, and transanal endoscopic microsurgery (TEM).
