Elevated/polypoid lesions (0-I) are defined as having more than double the amount of mucosal thickness in a histological specimen, while flat lesions (0-II) are less than that [1].

The NICE (NBI International Colorectal Endoscopic) Classification is based on narrow-band images of colon polyps. The classification uses staining, vascular patterns, and surface …

We aimed to provide an overview of polyp classification techniques to help surgeons select the correct treatment algorithm for advanced colorectal lesions based on their visual …

The size of the lesion plays an essential role in polypoid findings (Ip and Is) (although the Paris classification in the general sense only describes lesions less than 2 cm).

Accurate assessment of polyp size is one of the most important factors in determining the risk of cancer in a polyp. While polyp size can be measured easily following resection, open biopsy …

Type 0 to I lesions are subclassified as type 0 to Ip (pedunculated) and type 0 to Is (sessile) lesions. Type 0 to IIa lesions include those in which the height of the lesion does not exceed …

When analysing the data on polyp morphology assessments into just two categories, polypoid (Paris Ip, Isp, Is) vs. non-polypoid (Paris IIa, IIb, IIc, III) the Fleiss kappa remained ‘moderate’ …

2020年11月4日 · Lesions are classified as polyps (type 0–I), which include both pedunculated (0–Ip) and sessile (0–Is) morphologies; or flat lesions (type 0–II), which consist of slightly …

A malignant polyp is therefore an early carcinoma. It accounts for 0.75–5.6% 5 - 9 of large-bowel polyps removed in general diagnostic colonoscopy practice. The wide discrepancy is …

2024年4月11日 · The Paris classification (the most widely validated and accepted system used to describe colorectal polyp morphology in vivo, established by multidisciplinary expert …
