Use of clips at initial EMR increased diagnostic inaccuracy (adjusted OR=1.68(95% CI 1.01 to 2.75)). In offline assessment, specificity was high for all imaging modes (mean: ≥93% (range: 55%-100%)), while sensitivity was significantly higher for NBI-NF (82%(72%-93%)%)) compared with WL (69%(38%-86%); p<0.001), WL-NF (68%(55%-83%); p<0.001 ...

Endoscopic mucosal resection (EMR) is a minimally invasive, specialized endoscopic technique that is useful in resecting superficial gastrointestinal lesions that are unable to be removed by standard polypectomy.

post-EMR surveillance colonoscopy is to detect the area of scar, particularly if a prior tattoo is not placed or has faded. The second task is to distinguish scar from recurrent adenoma (ref1 and also PMID 31494134). Detecting scars and evaluating for polyp recurrence are both challenging visual tasks which may be aided by arti-

post-EMR lesions/scars, the initial median polyp size was 30 mm, and both groups had similar distributions in terms of size, morphology, site, and access scores. There were significant differences in EMR technique among the intervention group

Background and study aims: Piecemeal EMR of large (≥20mm) non-pedunculated colorectal polyps (LNPCPs) is succeeded by a 6-month surveillance endoscopy to evaluate the post-EMR scar for recurrence. Data from expert centers suggest that routine tattoo placement and scar biopsies can be omitted, but data from community hospitals are lacking.

2019年8月16日 · Wide-field endoscopic mucosal resection (EMR) is an advanced resection technique that has been shown to be an effective and relatively safe approach for the removal of large (> 20 mm), laterally spreading colorectal polyps.

2017年3月1日 · Endoscopic detection of RRA in the post-EMR scar is highly accurate using a standardized imaging protocol with HD-WL and NBI. This allows real-time, accurate detection of recurrence and its concurrent treatment, and raises the possibility that routine biopsy of the post-EMR scar may not be necessary.

2016年3月1日 · Endoscopic clips are increasingly used to mitigate the risk of delayed bleeding. Clips may alter the endoscopic appearance of the scar after EMR, interfering with the assessment of adenoma recurrence. We aimed to evaluate this.

2015年12月16日 · 内镜下黏膜切除术（emr）和内镜黏膜下剥离术（esd）在消化道疾病中的应用日益广泛，而这两者到底有何区别？又各自适应于何种疾病？一起来了解下。

2024年10月29日 · Endoscopic mucosal resection, or EMR, uses a specially designed endoscope or colonoscope to remove suspect tissue or polyps from your esophagus or colon. The tissue or polyp is first injected with a solution that raises a blister, allowing your doctor to remove the tissue without damaging the rest of the esophagus or colon.
