Spots Global Cancer Trial Database for EndoRotor® Endoscopic Mucosal Resection System for the Colon

Study Description

Brief Summary: The EndoRotor® is intended for use (USA labeling) in endoscopic procedures by a trained gastroenterologist to resect and remove tissue, not intended for biopsy, of the gastrointestinal (GI) system including post-endoscopic mucosal resection (EMR) tissue persistence with a scarred base and residual tissue from the peripheral margins following EMR. In this trial investigators will conduct a post-market, prospective, non-randomized, multi-center study for the treatment of subjects with the need for resection of recurrent flat or sessile colorectal lesions where EndoRotor is the primary resection modality of persistent adenoma with a scarred base.

Detailed Description: Although the majority of polyps are non-malignant, it is known that the risk of malignancy increases with polyp size, with polyps \< 10 mm having \< 1% risk of cancer, polyps of 10 mm having a 10% risk of cancer and polyps of 20 mm having a greater than 10% risk of cancer. It is also understood that a polyp of \< 1 cm takes approximately 10 years to transform into invasive colorectal carcinoma. Therefore, adenomas greater than 5 mm are normally treated. Polyps with tethered bases resulting from scarring are often the most challenging to resect endoscopically. The scarring can be caused by previous attempts at resection, previous deep biopsies, or tattoos placed too closely. These polyps often do not lift and can be impossible to snare even when stiff snares are used. Endoscopic submucosal dissection (ESD) and knife-assisted resection (KAR) are techniques that have been shown effective in the management of scarred polyps, however these techniques have not been widely adopted in the West. Argon plasma coagulation has been more commonly used to ablate adenomatous tissue in scarred polyps but this technique does not allow for the histological assessment of the scarred polyp and is less effective than ESD. The EndoRotor provides a technique whereby the lesion can be effectively removed without adjunct procedures with collection of tissue for histological assessment.
