PROGRAM DESCRIPTION
In an effort to precisely identify polyps and potentially neoplastic lesions in the gastrointestinal (GI) tract, the GI endoscopist uses chromoendoscopic and other visualization techniques to detect and determine their malignant potential and to select the appropriate resection technique. For dysplastic lesions confined to the mucosa, the clinical team has several options for lesion removal, including standard polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection. Surgery should be reserved for cases of suspected deeply invasive cancer. Endoscopic resection of superficial GI neoplasia is often facilitated by submucosal lifting of the lesion off of the deeper muscle layers, and the choice of which endoscopic resection techniques to use is determined by lesion size, location, morphology, and surface characteristics, as well as by the patient’s clinical history and any comorbidities.

EDUCATIONAL OBJECTIVES
After completing the activity, the participant should be better able to:Evaluate the spectrum of chromoendoscopic staining techniques to optimally identify and assess adenomatous polyps and other precancerous lesions in the gastric mucosaInstitute effective submucosal lifting methods to ensure complete endoscopic mucosal resection of polyps in the GI tract
