Objective:
This study aimed to investigate the relationship between colonic diverticulosis, colorectal polyps, and colorectal cancer.
Material And Methods:
A total of 648 patients (275 females, 373 males) who underwent complete colonoscopy between January 2016 and June 2020 were retrospectively analyzed. The presence and localization of diverticula, polyps, and cancer were recorded, and the association between diverticular disease and the formation of polyps and cancer was evaluated.
Results:
Diverticula were identified in 53 patients (8.2%), while 595 patients (91.8%) had no diverticula. Polyps were detected in 148 patients (22.8%), and no polyps were found in 500 patients (77.2%). Adenocarcinoma was diagnosed in 67 patients (10.3%), with no malignancy observed in 581 patients (89.7%). The mean age of patients with polyps was 59.5 years, compared to 53.3 years in those without polyps (p < 0.001). Multivariate logistic regression analysis revealed that diverticulum status did not significantly influence the risk of polyp formation, whereas advanced age was identified as a significant risk factor (p < 0.001).
Conclusion:
Advanced age is a significant risk factor for colorectal polyp formation, whereas diverticulosis is not an independent risk factor. These findings highlight the importance of age-based screening strategies for colorectal neoplasia.

01:27Inflammatory 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...

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
