Thulium laser-assisted colorectal endoscopic submucosal dissection.

ABSTRACT:

Background and aims

Thulium laser is emerging as an alternative energy source in endourologic applications due to its precise cutting capabilities, reliable hemostasis, and limited thermal injury. These features have promoted its adoption in urology and sparked interest in gastrointestinal endoscopy. In endoscopic submucosal dissection (ESD), thulium laser offers potential advantages over conventional electrosurgical knives, including shallow penetration depth, powerful coagulation, and precise dissection.

Methods

We describe the use of thulium laser-assisted colorectal ESD in a 68-year-old man with a 3.5-cm rectal polyp. Submucosal injection was followed by incision and complete dissection using the thulium laser.
