“…Although previous studies have reported SSA/Ps‐CD(+) in older female patients and in the proximal colon, there were no significant differences between SSA/Ps‐CD(−) and SSA/Ps‐CD(+) in this study. However, endoscopic morphological findings, such as large or small nodules on the surface and partial protrusion of the lesions, were significantly more common in SSA/Ps‐CD(+) than in SSA/Ps‐CD(−) (46.2% vs 2.7%, P < 0.01).…”

“…Tate et al reported that a demarcated area with a neoplastic pit pattern (Kudo type III/IV or NICE type II) in non-magnifying NBI observation was a useful indicator of CD within SSA/Ps, with an accuracy of 95.0%, sensitivity of 93.9%, and NPV of 98.1%. 17 However, as only SSA/Ps ≥ 8 mm were evaluated in their study, further studies are needed to determine whether this indicator can be applied to all SSA/Ps.…”

The aim of the present review was to clarify how we should detect and diagnose sessile serrated polyps (SSP) endoscopically. A systematic search was conducted of MEDLINE from January 2004 through March 2018. Nine findings: (i) proximal location; (ii) size >10 mm; (iii) irregular shape; (iv) indistinctive border; (v) cloud-like surface; (vi) mucus cap; (vii) rim of debris in white-light endoscopy; (viii) dilated vessels; and (ix) dilated crypts (pits) in image-enhanced endoscopy were considered to be candidate discriminators of SSP from hyperplastic polyps. Prospective studies in a general setting are warranted to validate the above-mentioned endoscopic features of SSP during real-time colonoscopy and to determine whether these features are useful for the differential diagnosis of SSP.

ObjectivesPrevious studies of cold snare polypectomy (CSP) for sessile serrated lesions (SSLs) ≥10 mm were performed by experienced endoscopists, and therefore their skills might have significantly influenced results. In this study, we compared the efficacy and safety of CSP for SSLs ≥10 mm between experienced and trainee endoscopists.MethodsIn a 1:1 propensity score matched retrospective cohort study, we compared the complete resection rate, en‐bloc resection rate, adverse event rate, and procedure time between experienced and trainee groups. Thirteen endoscopists performed CSP, and we defined the experienced group as endoscopists with board certification from the Japan Gastroenterological Endoscopy Society.ResultsWe examined 616 lesions with SSLs ≥10 mm resected by CSP between February 2018 and May 2022. We excluded 61 lesions from the analysis because they had simultaneously undergone hot snare polypectomy (n = 57) or had been taken over by experienced endoscopists from trainees in the CSP procedure (n = 4). Finally, we identified 217 propensity score‐matched pairs (n = 434). Between experienced and trainee groups, the results were complete resection rate (100 vs. 100%; p = 1.00), en‐bloc resection rate (73.2 vs. 75.6%; p = 0.24), adverse event rate (3.2 vs. 2.8%; p = 0.77), or procedure time (6.2 vs. 5.9 min; p = 0.64).ConclusionsWe have demonstrated the safety and efficacy of CSP for SSLs ≥10 mm performed by experienced and trainee endoscopists.
