Abstract:
Patients with inflammatory bowel disease (IBD) are subject to increased risks for the development of colorectal cancer (CRC), risks that are attributed to the duration and anatomic extent of disease in patients with ulcerative colitis and Crohn's disease. Although IBD contributes only 1%-2% to all cases of CRC, the mortality rate in patients with a diagnosis of CRC in the setting of IBD is higher than for those afflicted with sporadic cases of CRC. Given the length of time from IBD onset to the development of CRC, surveillance continues to be widely practiced. Although still under development, novel techniques for the earlier detection of dysplastic lesions have moved to the forefront in an attempt to optimize surveillance strategies and decrease the risk of CRC development.

Inflammatory Bowel Disease I: Ulcerative Colitis
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...
Inflammatory 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...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
