Abstract:
The high incidence of colonic diverticular disease (DD) in the general population is a serious public health problem. According to statistics, DD is among the top five most common colorectal diseases. Complicated course of DD is observed in 12-15% of patients, and in 10.7% of cases can lead to death. Algorithms and recommendations for predicting the complicated course of DD for further prevention have not been developed.
Objective:
Comparative analysis of clinical data and structural characteristics of the colonic muscular tissue in patients with different course of DD and without colonic diverticula to identify morphological predictors of a complicated DD.
Material And Methods:
A comparative analysis of clinical data, pathomorphological and ultrastructural changes of the colonic musculature in the surgical material from 68 patients undergoing left-sided hemicolectomy was carried out.
Results:
The operative material of 37 patients with complicated course of DD, 19 with uncomplicated course of DD and 12 without diverticula was analyzed. In men, this disease occurs at a younger age than in women (Median age of men 49 (39.5; 61) years, women 66.5 (58; 81) years; U=178, p<0.001). It was shown that the area occupied by connective tissue fibres in the colonic musculature in patients with a complicated DD was 5 times greater (15%) than in observations with an uncomplicated DD (3%) and 50 times greater than in cases without colonic diverticula (0.3%; p<0.001).
Conclusion:
The present study demonstrates age- and sex-specific features of DD, as well as significant differences in the prevalence of fibrosis of the colonic musculature, which can be considered as a potential predictor of a complicated course of DD.

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...
Chronic Bowel Disorders: Introduction
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 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...
