Among patients with polyps, the prevalence of inflammatory polyps was higher in the IBD group (55%) compared to the NIC group (12%). After adjusting for age, sex and race, odds ratio of inflammatory polyps in IBD patients was 6.0 (P = 0.016). Adenoma prevalence was 4.3% (3/70) in IBD patients and 3.9% (16/415) in the NIC patients (p = 0.75).

PIPs were present in 1944/5424 (35.8%) IBD patients (median prevalence, 29.7%). The median follow-up durations ranged from 3.0 to 22.9 years (median follow-up, 13.0 years). In different IBD phenotypes, five studies exclusively focused on ulcerative colitis (UC), and four remaining studies focused on mixed IBD phenotypes.

Aim: Patients with long-standing inflammatory bowel disease (IBD) have higher risk for developing dysplasia and colorectal cancer and consequently surveillance colonoscopy is required. The colonic lesion in these patients are often flat and subtle and may be difficult to detect by white light standard endoscopy.

2022年1月21日 · Post-inflammatory polyps (PIPs) are visible markers of severe inflammation under endoscopy. To date, there is controversy regarding the necessity of strengthened surveillance strategies for IBD patients with PIPs. Aim: To determine whether IBD patients with PIPs carryan increased risk of colorectal neoplasia.

Patients with inflammatory bowel disease (IBD) may develop a variety of neoplastic and nonneoplastic polyps. This review covers the pathology, pathogenesis, natural history, and treatment of polyps in IBD with special emphasis on dysplastic lesions.

2021年2月17日 · There is evidence that IBD-related invisible/flat dysplasia may have different molecular features compared with visible/polypoid dysplasia.

2020年6月5日 · Our study shows that inflammatory polyps are more common in IBD patients when compared to NIC patients. Most polyps were in the same location as the colitis. Ulcerative Colitis (UC) and Crohn’s disease (CD) are the two major …

2025年3月19日 · We also compared the clinicopathologic features of serrated dysplasia with those of 239 conventional (adenomatous) dysplastic lesions from 149 IBD patients. The cohort included 39 (67%) men and 19 (33%) women, with a mean age of 54 years and a mean IBD duration of 20 years.

2020年6月5日 · Among patients with polyps, the prevalence of inflammatory polyps was higher in the IBD group (55%) compared to the NIC group (12%). After adjusting for age, sex and race, odds ratio of inflammatory polyps in IBD patients was 6.0 (P = 0.016).

1991年3月1日 · Postinflammatory (filiform) polyps--fingerlike projections of submucosa covered by mucosa on all sides--reflect healing of undermined mucosal and submucosal remnants and ulcers and are almost always multiple. Patients with ulcerative colitis or Crohn disease are at increased risk for developing adenocarcinoma.
