Complex Colorectal Polypoid Lesion

Complex Colorectal Polypoid Lesion
A rebroadcast of an important topic and discussion from a panel of experts who will discuss management of complex colorectal polyps. Although there are no hard-and-fast rules, endoscopic mucosal resection (EMR) of complex colorectal polyps is appropriate for mucosal polyps of any size and for superficial T1a colorectal cancer with a diameter <2cm (limited invasion into the submucosal layer, lack of lymphovascular invasion). In patients who present with evidence of deep invasion, demonstrated by induration, ulceration, and the non-lifting sign with submucosal injection, an alternative approach should be considered. Traditionally, rectal lesions deemed endoscopically unresectable required a segmental oncologic resection, with either an abdominoperineal or a low anterior resection; both procedures carry a significant risk of perioperative adverse events. More recent alternatives for management of complex colorectal polyps include endoscopic submucosal dissection (ESD), endoscopic full-thickness resection (EFTR) and transanal endoscopic surgery for select early (T1) rectal cancers.


  1. Discussion between gastroenterologists and surgeons on managing rectal neoplasia for the most favorable clinical outcomes.
  2. Raise awareness of the gastroenterologists’ understanding of transanal minimally invasive surgery (TAMIS) for rectal neoplasia management.
  3. Opportunity for both groups to share perspectives on how to navigate patients within the realm of options.
  4. To enhance communication and collaboration between gastroenterologists and surgeons.
