Near-focus versus Normal-focus Narrow Band Imaging Colonoscopy in Diagnosis of Colorectal Polyps based on Combined NICE and WASP Classification in routine colonoscopy: a Randomized Controlled TrialNisa Netinatsunton1, Natcha Cheewasereechon1Tanawat Pattarapuntakul1, Jaksin Sottisuporn1, Kanet Kanjanapradit2, Bancha Ovartlarnporn1Background: NICE (NBI International Colorectal Endoscopic) and WASP (Workgroup on Serrated Polyps and Polyposis) classification were developed for optical diagnosis of adenoma and sessile serrated polyps, respectively. Near focus NBI with NICE combined with WASP criteria for optical diagnosis of colonic polyps has not been assessed formerly. Aims: To compare the accuracy of near focus NBI (group A) with normal focus NBI (group B) in real time optical diagnosis of colorectal polyps using combined NICE and WASP criteria.Methods: 118 out of 362 patients with 227 polyps were recruited. 62 patients with 130 polyps (3 lost polyps) were assigned to group A and 56 patients with 106 polyps (6 lost polyps) were assigned to group B. Optical diagnoses were compared with pathological reports.Results: The performance of optical diagnosis of neoplastic polyps in group A compared with group B in terms of accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) was not significantly difference (76%, 72%, 81%, 86%, 64%, in group A, and 71%, 66%, 83%, 90%, 51%, in group B, respectively). Combined NICE and WASP criteria provided all false positive diagnosis of sessile polyps as serrated polyps in 31 (15.9%).Conclusions: Near-focus NBI was not superior to normal-focus NBI in in optical diagnostic of neoplastic polyps using NICE criteria. Combined NICE and WASP classification yielded all false positive in the diagnosis SSAPs in our study. Routine real life optical diagnosis of polyps is still not recommended.Trial registration: Clinical Trials.gov, NCT 04831814, was retrospectively registered on 04/01/2021.

“…AAS has been previously reported to cause an aceto-whitening reaction when used on SSLs, such as sessile serrated adenomas/polyps (SSA/Ps); when combined with narrowband imaging (NBI), it becomes an effective tool in identifying polyps and their margins. [5][6][7][8] To our knowledge, the use of AAS combined with pCSP (AAS-pCSP) has not been previously presented. We present our experience with AAS-pCSP in SSA/P resection.…”

“…However, the intended device-assisted endoscopic full-thickness resection (EFTR) could not be performed due to lack of passage through the sharply angulated sigmoid by the full-thickness resection device (FTRD) test cap (FTRD prOVE Cap, Ovesco, Germany)[4]. Beyond the previously detected small sessile lesion, the full lesion extent was, at the time, visualized after ineffective submucosal indigo carmine injection related to exuberant postsurgical fibrosis and acetic acid spraying, albeit as yet with low-level evidence, highlighting the serrated lesion and its borders [5, 6]. The appendix rest was, in addition, distended by underwater endoscopy, revealing a carpet-like involvement with a diffusely velvety appearance (Fig.…”
