Colon polypColonoscopyHigh grade dysplasiaSurveillanceBackground The risk of recurrent colonic adenoma associated with high-grade dysplasia (HGD) colon polyps at baseline colonoscopy remains unclear. We conducted a clinical cohort study with patients who underwent polypectomy during screen colonoscopy to ...

Polyps were categorized by size, morphology and location in the colon. Average polyp size and morphology were determined for each location. Results During the study period, 564 patients with APNs were identified. Of these, adenocarcinoma was noted in 21.6% and high-grade dysplasia in 78.4%. The...
Our study demonstrates that presence of HGD in the large polyp is strongly associated with co-occurrence of synchronous polyps with the same histology. This observation is supported by a study showing that occurrence of adenomas with advanced dysplasia in the distal colon is predictive of advanced ...
with dye staining. One very important issue that will have to be explored in future studies is whether FICE or NBI can aid in the recognition of depressed lesions (Paris type 0-IIc). These lesions are frequently small but frequently harbour high grade dysplasia or early invasive cancer[11,17...
