Abstract:
It has been widely accepted that long-standing cases with ulcerative colitis, especially pancolitis have higher risk of complicating colitic cancer. Colitic cancer often appears as multi-focal invasive features with un-differentiated histology. Therefore, endoscopic diagnosis of precancerous or cancer associated dysplastic lesions. Surveillance colonoscopy has preventing effects for developing colitic cancer. In western world, annual surveillance colonoscopy with multiple stepwise has been adopted. In Japan, surveillance colonoscopy with targeted biopsies assisted by chromoendoscopy and/or magnifying endoscopy has proven to be efficacious in finding such lesions.

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...

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...
