Using Narrow Band Imaging in Colonoscopy | March 2021-Webinar Recording

Video Transcription

Video Summary

The video presentation focused on the use of narrowband imaging (NBI) in colonoscopy. The presenter discussed the classification system called NICE (NBI International Colorectal Endoscopic Classification), which categorizes lesions into type 1 (serrated lesions), type 2 (adenomas), and type 3 (lesions with deep submucosal invasion). The presenter highlighted the use of NBI in identifying NICE 3 features, which indicate deep submucosal invasion and often require surgical treatment. They also discussed the differentiation of type 1 and type 2 lesions using NBI, with type 1 lesions showing uniform pits and thin vessels, and type 2 lesions showing variable pits, thick vessels, and brown color. The presenter emphasized the importance of inspecting the entire surface of a lesion and biopsy from the affected area. They also mentioned the use of NBI in evaluating EMR scars and identifying clip artifacts and recurrent polyps. The presenter recommended using NBI for detection and differentiation during the withdrawal phase of colonoscopy, particularly for serrated lesions and larger adenomas. They also suggested using MBI for resect and discard, leaving distal hyperplastic polyps in place, and triaging patients for surgery based on NICE 3 features. The presenter provided examples of lesions and their endoscopic and histologic features. They also mentioned the use of other image enhancement modalities, such as blue light imaging, and referred to additional resources for further reading and education on NBI.
