Significant esophageal morbidity associated with EA extends into adulthood. Surgical complications, increasing age, and impaired esophageal motility predict development of epithelial metaplasia after repair of EA.

Clinical scores commonly used in the assessment of disease activity are unreliable at differentiating endoscopic remission from active CD. Despite this, a score based on a combination of fecal calprotectin and the HBI is a new promising tool for identifying endoscopic remission.

FC seems to increase and remain elevated before clinical or endoscopic relapse, suggesting that it can be used as a surrogate marker for predicting and identifying patients requiring close follow-up in clinical practice.

Patients with long-standing inflammatory bowel disease (IBD) have an increased risk for colorectal carcinoma (CRC). Earlier studies suggest that the severity of inflammation is an independent risk factor for CRC in ulcerative colitis (UC). We investigated the role of histological inflammation as a risk factor for colorectal dysplasia or CRC to better target dysplasia surveillance in IBD. By combining our hospital patient registry and pathology database between 1996 and 2008, we identified 183 IBD patients with dysplasia or CRC. The control group was collected from our registry of IBD patients. Histological severe inflammation was present in 41.4% of patients with dysplasia and in 24.1% of patients with CRC, but in only 4.3% of controls. Severe inflammation had an odds ratio (OR) of 31.8 [95% confidence interval (CI): 15.6-64.9] for dysplasia or carcinoma compared to patients with no inflammation. Among patients with mild to moderate inflammation, the OR was 2.6 (95% CI: 1.6-4.1). Disease duration increased the annual risk for dysplasia or CRC by 4.5%. Coexisting primary sclerosing cholangitis (PSC) did not elevate the risk, whereas use of thiopurines (OR 5 0.09, 95% CI: 0.02-0.33) and also 5-aminosalicylic acid (OR 0.17, 95% CI: 0.017-1.01) protected against CRC. As conclusion, degree of inflammation and duration of disease cumulatively increase the risk for dysplasia and CRC. PSC was not identified as a risk factor. We demonstrated that use of thiopurines strongly protects against CRC. These results can be applied to better target dysplasia surveillance in IBD patients.

After cessation of TNFα-blocking therapy in patients with IBD in deep remission, up to 67% remained in clinical remission during the 12-month follow-up. Importantly, 85% of these patients sustained endoscopic remission. The response to restart of TNFα antagonists was effective and well tolerated.
