Background:
Although small bowel and esophagus neoplasia are recognized to occur more frequently in patients with celiac disease, the association with colorectal cancer is still controversial.
Objective:
To determine the risk of colorectal neoplasia among patients with celiac disease.
Methods:
A case-control study was conducted using the gastroenterology and endoscopy unit electronic data base. Patients with celiac disease and colonoscopy were regarded as cases and those without celiac disease and colonoscopy as controls. Patients were matched for age, sex, colonoscopy purpose and family history of colorectal cancer. The main outcome was the risk of colorectal polyps, adenomas, advanced lesions and cancer. The risk was expressed as odds ratio (OR) with the respective 95% confidence intervals (95% CI).
Results:
Out of 178 celiac disease patients, 44 were included as cases. Eighty-eight non-celiac patients were included as controls. In cases, the presence of polyps, adenomas and advanced colonic lesions was 20%, 16% and 4.5%, respectively. In controls, it was 15%, 9% and3.4%, respectively. The risk of polyps, adenomas and advanced colonic lesions was similar in both groups: OR 1.48 (95% CI 0.59-3.73), OR 1.89 (95% CI 0.66-5.42) and OR 1.34 (95% CI 0.26-7.05). No colorectal cancer was identified.
Conclusion:
The risk of colorectal neoplasia within this cohort of patients with celiac disease was similar to the control population.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
