Endoscopic full-thickness resection (EFTR) offers an alternative for colonic lesions when other methods fail. Neoadjuvant chemotherapy may enable EFTR for larger lesions, but risks of perforation exist with concurrent therapy.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Oncology
Background:
- Endoscopic full-thickness resection (EFTR) is emerging for colonic lesions unsuitable for endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD).
- ESD presents a steep learning curve and limited adoption in Western countries.
- EFTR indications are expanding, with the Full-Thickness Resection Device (FTRD) showing promise despite limitations.
