The CARMA Technique Study

Condition(s) studied

Investigational drug(s) / intervention(s)

CARMA technique: Once standard polyp resection and assessment of the polypectomy site without magnification is completed, the CARMA technique will be applied. This will involve an assessment of the entire polypectomy margin using cap assisted magnification endoscopy with the ability to also use NBI (at the endoscopist's discretion) and documentation of any residual polyp noted.

Study summary

Colonoscopic removal of polyps is an important and well-established tool in the prevention of colorectal cancers. However, high polyp recurrence rates after endoscopic resection, with resultant development of interval cancers, remains a problem; this most commonly stems from unrecognised incomplete polyp resection. Thus, a standardised endoscopic technique is needed that will allow endoscopists to consistently achieve a clear margin of resection. The investigators believe the Cap Assisted Resection Margin Assessment (CARMA) technique will address this problem. This novel technique focuses on a standardised assessment of the resection margin after endoscopic polypectomy utilising available standard high-definition video endoscopes with imaging features including narrow band imaging (NBI) and magnification endoscopy.
