Mean age of the 420 patients with complete follow up was 67.4 years, mean polyp size 32.3mm, and 253 polyps were 鈮 3cm in size. Location was cecum 113, ascending colon 133, transverse 114, descending 22, sigmoid 31, rectum 61. There were 183 polyps removed before clips were available...
sessile serrated polypsessile serrated polyp/adenomaThe aim of the present review is to clarify how we should detect and diagnose SSPs endoscopically. A systematic search was conducted of MEDLINE, from January 2004 through March 2018. Nine findings: a) proximal location, b) size>10mm, c) ...
Fig. 2 Immunohistochemical staining in a representative case of sessile serrated adenoma/polyp (SSA/P) with dysplasia (Case #2). a Dilated crypts and deep serration, corresponding to SSA/P, were seen on the left side, and high-grade dysplasia without submucosal invasion was seen on the right...
In the prevalence of synchronous colorectal neoplasms in patients with SSA/P, 210 (39.5%) patients had conventional adenoma with low-grade dysplasia, 129 (24.2%) had hyperplastic polyp, 31 (5.8%) had conventional adenoma with high-grade dysplasia, 30 (5.6%) had traditional serrated adenoma, ...
Efficacy and Safety of Cold Versus Hot Snare Endoscopic Mucosal Resection in Colorectal Polyp Removal Cold snare endoscopic mucosal resection (C-EMR) is hypothesized to offer a safety advantage over hot snare endoscopic mucosal resection (H-EMR). The primar... C Niu,J Zhang,U Joshi,... - 《...
The overall mean polyp size was 18 mm ± 10.9 mm and the median was 20 mm (range 3-50 mm). Results are summarized in the table. Male gender and cumulative number of polyps were associated with dysplasia (p=0.05, p=0.031, respectively). No statistical difference was observed in age, ...
6. Push the snare slide handle until the snare shred is fully out of the sheath and place the shred around the polyp to be resected. In order to successfully capture polyps, the cutting plane should be perpendicular to the polyp pedicle. When not vertical...

COX-2 expression in adenoma/polyp cells was interpreted as negative (no overexpression), weak overexpression (1+), or strong overexpression (2+) (Figure 2). COX-2 expression in adenomas and polyps was often heterogeneous and we interpreted as overexpression even if staining of tumor cells was ...
Rates of subsequent colonoscopies, polypectomies, and CRCs were identified.RESULTS:We enrolled 2,527 persons who underwent colonoscopy in whom 111 had HPs >5 mm. Thirty-two of the 111 participants (28.8%) with HPs >5 mm had their polyps reclassified as SSA/Ps. There were no ...
