Video Tip: Diagnosing Cancer Arising in a Sessile Serrated Lesion | November 2022-Diagnosing Cancer Arising in a Sessile Serrated Lesion

Video Transcription

Video Summary

The video is about a 74-year-old woman with a history of polyps who was referred for resection of a lesion in the cecum. However, the lesion is found a couple of folds distal to the ileocecal valve, with a tattoo marking its original location. The video shows the examination of the lesion in white light and then in narrow band imaging, with optical magnification activated and the lesion being washed due to blood. The lesion is determined to be clearly malignant, with an ulcer occupying two thirds to three quarters of the surface area, disrupted vasculature, and KUDO5 changes in the base of the ulcer. There is a regular pit pattern within a red-lined area, indicating that the cancer developed from an SSL. The video was made possible by an educational grant from Braintree, a part of Cibela Pharmaceuticals, makers of SUTAB.
