Ospital between March and February have been retrospectively reviewed. The lateral and deep margins on the resected polyps have been evaluated to check the resection completeness. Outcomes: A total of ,adenomatous polyps from ,sufferers were included. Of those polyps,, were removed by 3 specialists and , had been removed by seven fellows. In the experttreated group,polyp size ! mm (odds ratio [OR] self-confidence interval [CI] . P),rightsided place (OR CI . P),and sessile variety (OR CI . P) was associated with incomplete resection. Inside the fellowtreated group,not only polyp qualities (rightsided location [OR CI . P .]),but the cumulative number of procedures was also associated to resection completeness. Immediately after consecutive polypectomies,the comprehensive resection rate of the fellows was comparable to that in the authorities.A Conclusion: Inside the fellowtreated group,the level of procedure practical experience was closely associated using the outcome of colonoscopic polypectomy. Meticulous focus is crucial to make sure the completeness of polypectomies performed by trainee endoscopists through the education system.

Chaussade Gastroenterology and endoscopy unit,Anatomopathology,Hopital Cochin APHP,Paris,France Contact Email Address: johann.dreaniccch.aphp.fr Introduction: The accuracy inside the differentiation of colonic polyps would let a “resect and discard” approach for smaller colonic lesions. Recently,the ESGE suggested “that virtual chromoendoscopy might be utilized for realtime optical diagnosis of diminutive ( mm) colorectal polyps to replace the histopathological diagnosis”. Blue Laser Imaging (BLI),can be a new endoscopic system (FujifilmJapan) connected with magnification,which can potentially additional enhance the differentiation of polyps. The aim of this study was to measure the diagnostic accuracy of polyp assessment (adenomatous versus hyperplastic) in MSX-122 compact (mm) and pretty smaller polyps ( mm),to allow a “resect and discard strategy” predict using BLI and zoom magnification. Aims Approaches: Colonic polyps mm were prospectively integrated within the study. Every polyp was evaluated with whitelight,common BLI,BLIbright,with and without PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/19389808 magnification (Zoom). Photos and video had been performed for every polyp. Professional endoscopists reviewed all pictures and videos blindly,and classified polyps working with size and also the Paris,Good,WASP and Sano classifications. Histological findings were correlated with clinical and endoscopic findings. Polyps had been classified according the histopathological diagnosis amongst neoplastic lesi.
