Background. Sessile serrated adenomas/polyps (SSA/Ps) and traditional serrated adenomas (TSAs) have not been well characterized in patients with inflammatory bowel disease (IBD). This study assesses the prevalence and anatomic distribution of SSA/Ps, TSAs, and conventional adenomas/dysplasia (Ad/Ds) in IBD patients. Methods. IBD patients with serrated, adenomatous, or hyperplastic lesions between 2005 and 2009 were identified in the regional tertiary-care hospital database. Clinicopathological information was reviewed and the histology of biopsies was reevaluated...

PURPOSE: Inflammatory bowel disease may be associated with extraintestinal manifestations. We report a case of severe reactive epithelial atypia resembling ocular surface squamous neoplasia (OSSN) in a patient with ulcerative colitis (UC). METHODS: Case report. RESULTS: A 32-year-old woman presented with sequential, progressive keratoconjunctival lesions in the left and right eyes, and both lesions were excised. Anterior segment optical coherence tomography demonstrated features similar to OSSN, whereas histological examination revealed severe reactive epithelial atypia mimicking severe dysplasia...

BACKGROUND & AIMS: Inflammatory bowel diseases (IBD) increase the risk of colorectal cancer. Surveillance colonoscopy with chromoendoscopy is recommended, but conventional forward-viewing colonoscopy (FVC) detects dysplasia with low levels of sensitivity. Full-spectrum endoscopy (FUSE) incorporates 2 additional lateral cameras to the forward camera of the colonoscope, allowing endoscopists to view behind folds and in blind spots, which might increase dysplasia detection. We compared FUSE vs FVC in the detection of dysplasia in patients with IBD...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice...

Although KRAS and TP53 mutations are common in both inflammatory bowel disease-associated colorectal cancer (IBD-CRC) and sporadic colorectal cancer (S-CRC), molecular events leading to carcinogenesis may be different. Previous studies comparing the frequency of KRAS and TP53 mutations in IBD-CRC and S-CRC were inconsistent. We performed a meta-analysis to compare the presence of KRAS and TP53 mutations among patients with IBD-CRC, S-CRC, and IBD without dysplasia. A total of 19 publications (482 patients with IBD-CRC, 4,222 with S-CRC, 281 with IBD without dysplasia) met the study inclusion criteria...

BACKGROUND AND AIM: The risk of developing colorectal cancer is higher in patients with ulcerative colitis (UC) than in the general population. Guidelines recommend surveillance colonoscopy (SCS) to reduce mortality; however, few studies have assessed physicians' adherence to guidelines. This study was aimed to clarify the current status of SCS and adherence to guidelines through the characteristics of cancer/dysplasia surveillance for UC patients in Japan. METHODS: A questionnaire was mailed to 541 physicians who attended meetings on inflammatory bowel disease...

BACKGROUND AND AIMS: Diminutive (1-5 mm) and small (6-9 mm) polyps comprise 90% of detected lesions during colonoscopy and rarely contain advanced histology or colorectal cancer (CRC). Routine removal of these lesions results in a significant burden to colonoscopy programs. At the same time, the risk for progression of these polyps to CRC is unclear. We performed a systematic review to explore the natural history of diminutive and small colorectal polyps. METHODS: We searched MEDLINE and EMBASE for studies investigating the natural history of colorectal polyps...

Background and study aims Current guidelines recommend the use of pancolonic chromoendoscopy for surveillance of patients with inflammatory bowel disease (IBD). It is currently unknown whether low grade dysplasia (LGD) found using chromoendoscopy carries a similar risk of high grade dysplasia (HGD) or colorectal cancer (CRC) compared with LGD detected using white-light endoscopy (WLE). The aim of this study was to compare the risk of advanced neoplasia, a combined endpoint of HGD and CRC, during follow-up after detection of lesions containing LGD identified with either chromoendoscopy or WLE...

Patients with inflammatory bowel disease involving the colon are at increased risk for developing colorectal cancer. Colonoscopy surveillance is important to identify and treat IBD associated dysplasia. The SCENIC consensus provides evidence-based recommendations for optimal surveillance and management of dysplasia in IBD. Chromoendoscopy, with the surface application of dyes to enhance mucosal visualization, is the superior endoscopic surveillance strategy to detect dysplasia. Most dysplasia is visible, and can be endoscopically resected...

Hypertrophic osteoarthropathy (HOA) is a medical condition characterized by abnormal proliferation of skin and periosteal tissues involving the extremities and characterized by three clinical features: digital clubbing (also termed Hippocratic fingers), periostosis of tubular bones, and synovial effusions. HOA can be a primary entity, known as pachydermoperiostosis, or can be secondary to extraskeletal conditions, with different prognoses and management implications for each. There is a high association between secondary HOA and malignancy, especially non-small cell lung cancer...

BACKGROUND AND AIMS: Restorative proctocolectomy in elderly inflammatory bowel disease [ IBD] patients is controversial and limited data are available on the outcomes of surgery. The aim of this study was to evaluate the safety, efficacy, and long-term results of ileal-pouch-anal anastomosis in elderly patients, in a multicentre survey from European referral centres. METHODS: The International Pouch Database [IPD] combined 101 variables. Patients aged ≥ 65 years were matched on the basis of open versus laparoscopic surgery with a control group of consecutive younger unselected patients with a ratio of 1:2...

BACKGROUND AND AIMS: The chemopreventive effect of 5-aminosalicylic acid (5-ASA) in patients with inflammatory bowel disease (IBD) has been widely studied; however, the results remain conflicting. The aim of this study was to systematically review the literature and update evidence concerning effects of 5-ASA on the risk of colorectal cancer (CRC) and dysplasia (Dys) in patients with ulcerative colitis (UC) or Crohn's disease (CD). RESULTS: 5-ASA showed a chemopreventive effect against CRC/Dys in IBD patients (OR = 0...

BACKGROUND & AIMS: Key international guideline agencies recommend dysplasia surveillance in inflammatory bowel diseases with chromoendoscopy. We performed a systematic review of randomized trials comparing chromoendoscopy versus other endoscopic techniques for dysplasia surveillance in inflammatory bowel diseases. METHODS: We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials for relevant studies published through September 2016. We estimated risk ratios (RR) for dichotomous outcomes (all-cause/colorectal cancer-related mortality, time to interval cancer, patients with dysplasia, total/subtypes of dysplastic lesions, dysplasia detected by targeted biopsies, adverse events), mean differences (MD) for continuous outcomes (procedural time, costs, total/targeted biopsies) and their 95% confidence intervals (CI) using a random-effects model...

In Digestive Disease Week 2016, interesting data were presented on the eventual role of certain foods in inflammatory bowel disease, although the value of these data is relative. Also of interest were epidemiological studies, of which several analysed the natural history of the disease. Some presentations dealt with the search for individual predictive factors, a pressing need in clinical practice. Unfortunately, some of the findings presented were of dubious value. A study suggesting that a simple parameter as increased blood monocytes could be a clear predictive factor of poor outcome could perhaps be highlighted (the results were striking but had multiple limitations)...

This review chronicles the evolution of dysplasia detection and management in inflammatory bowel disease since 1925, the year the first case report of colitis-related colorectal cancer was published. We conclude that colorectal cancer prevention and dysplasia management for patients with inflammatory bowel disease has changed since this first case report, from somewhat hopeless to hopeful.

Crohn disease and ulcerative colitis are chronic inflammatory bowel diseases (IBD) characterized by recurrent episodes of mucosal inflammation. This chronic mucosal inflammation has several potential consequences, one of which is the occurrence of colitis-associated colorectal cancer. Over the past decade, our understanding of the epidemiology, pathophysiology, and overall approach to diagnosing and managing colitis-associated colorectal cancer has grown considerably. In the current review article, we outline these advancements and highlight areas in need of further research...
