Is this trial a fit for you?

Likely a good fit

Adults over 18 with an adenoma or early carcinoma >2 cm located in the rectum or distal sigmoid colon who are eligible for endoscopic submucosal dissection and can provide written informed consent.

Probably not a fit

Patients with anal stenoses or fistulas, lesions within 2 cm or beyond 20 cm of the anocutaneous line, those unable to consent, pregnant or breastfeeding individuals, and some patients on anticoagulant therapy may not receive benefit.

What this trial studies

This interventional pilot uses the EndoTEM bi‑manual resection platform during endoscopic submucosal dissection to remove adenomas or early carcinomas larger than 2 cm in the rectum or distal sigmoid colon. Patients receive standard peri-procedural care and complete questionnaires on fecal continence and quality of life before and after the intervention. The study documents whether en bloc (one‑piece) resection is achieved and carefully monitors for procedure‑related complications and safety events. Procedures are performed at participating German hospitals using the EndoTEM technique.

Why it matters

Potential benefit: If successful, EndoTEM could allow safer, more complete endoscopic one-piece removal of large distal colon polyps and reduce the need for surgical resection.

How similar studies have gone: Endoscopic submucosal dissection is an established technique for en bloc resection, but the bi‑manual EndoTEM platform is a novel device with limited published clinical data so far.
