Abstract
Many colorectal cancers arise from either adenomatous polyps or sessile serrated lesions.
However, due to the implementation of screening guidelines at the age of 45 years
and the ability to perform therapeutic endoscopic polyp resections, the incidence
and mortality of colorectal cancer has been decreasing in the United States. Polyps
can be distinguished not only by pathology, but characterized by their complexity
depending on the size, location, and morphology. Historically, polyps that were endoscopically
more challenging to resect were referred for surgical resection. However, due to rapid
advancement in endoscopic techniques and availability of tools, many of these complex
polyps can be safely and effectively resected endoscopically. In this section, we
review the different methods and potential challenges associated with endoscopic resection
techniques including endoscopic mucosal resection, endoscopic submucosal dissection,
or endoscopic full-thickness resection of a complex polyp.
