The latest capped endoscope will be flexed up against haustral folds, flattening them. A far greater look at this new mucosa outside the flex can then be obtained. Westwood mais aussi al. 38 recently analyzed authored expertise in this process and found an enthusiastic rise in polyp detection and you may caecal intubation prices.

So far there isn’t any reputable answer to precisely expect cancerous change in an effective polyp, but you can find top features of polyp proportions, contour, consistency, facial skin and you may vascularity which should alert the newest endoscopist to help you you are able to malignancybining higher level imaging modalities get sooner promote an enthusiastic ‘optical biopsy’ 39 . Knowledge and you can perfect the means to access these detailed methods lets malignant exposure stratification.

Polyp size

The Erlangen Group 40 examined 11 188 adenomatous polyps in a European series from 1978 to 1993.
