Endoscopic Imaging of a Polyp on the Dentate Line after Previous Radiotherapy

The assessment of rectal polyps is conducted using a Fujifilm EG-760Z gastroscope. It highlights the need to switch between detection and characterization modes to differentiate polyp characteristics. The analysis identifies a scar from past cancer treatment and checks for recurrent lesions. It confirms no evidence of recurrent cancer in dysplastic lesions and recommends ESD for lesion removal due to fibrosis challenges.
