Abstract:
The most common premalignant lesions of colorectal carcinoma include sporadic adenomas. Tubular and tubulovillous adenomas with mild dysplasia are considered benign lesions, while villous adenomas represent tumors with uncertain bio-logical behavior. In recent years, demonstrable growth of flat lesions in the proximal intestine has been seen. Precision and yield of colonoscopy depends to some extent on good preparation, careful screening of intestine and use of new instruments of better quality. As an indicator of screening colonoscopy quality, the so -called adenoma detection rate is used. The text briefly describes options of endoscopic and surgical resolving of premalignancies. In the Czech Republic, attendance in the screening program is low, which could be changed by prepared addressed invitations of clients. The population with a genetic or familiar risk is examined according to recommended procedures intended for increased- risk persons.

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...
