Polyp Segmentation Using a Hybrid Vision Transformer and a Hybrid Loss Function
AbstractAccurate and early detection of precursor adenomatous polyps and their removal at the early stage can significantly decrease the mortality rate and the occurrence of the disease since most colorectal cancer evolve from adenomatous polyps. However, accurate detection and segmentation of the polyps by doctors are difficult mainly these factors: (i) quality of the screening of the polyps with colonoscopy depends on the imaging quality and the experience of the doctors; (ii) visual inspection by doctors is time-consuming, burdensome, and tiring; (iii) prolonged visual inspections can lead to polyps being missed even wh...

Delays in definitive endoscopic resection of previously manipulated colorectal polyps as a risk factor for inferior resection outcomes
Manipulation of colorectal polyps by biopsy, incomplete resection or tattoo placement under the lesion has been shown to cause submucosal fibrosis and associated inferior outcomes. The effect of delays between index manipulation and definitive resection on the incidence of fibrosis is unknown. (Source: Gastrointestinal Endoscopy)
