Background:
Extraintestinal manifestations significantly affect the quality of life of patients with Crohn's disease. The aim of the present study is to define the risk factors for extraintestinal manifestations and the relative influence of intestinal surgery.
Patients And Methods:
In a cohort of 223 patients with Crohn's disease we analyzed the association between demographic/clinico-pathological factors and extraintestinal manifestations. In addition, we evaluated their association with the timing of appearance of the extraintestinal manifestations with respect to the intestinal surgery.
Results:
Fifty-seven patients (25.6%) developed 91 extraintestinal manifestations. Demographic and clinico-pathological variables significantly associated with extraintestinal manifestations were: female gender (OR 2.84, 95% CI: 1.37-5.90) and colonic involvement (OR 2.68, 95% CI: 1.06-6.76). In patients not undergoing surgery and in patients with extraintestinal manifestations present only before surgery, the latency period between the onset of Crohn'S disease and extraintestinal manifestations were 3.7 +/-8.2 and 2.1 +/- 6.3 years, respectively. In patients developed extraintestinal manifestations only after surgery, the latency between surgery and extraintestinal manifestations was 12.0 +/-10.0 years. In 5 patients with early onset of extraintestinal manifestations, these did not regress or recur after surgery.
Conclusion:
Female gender and colonic involvement are confirmed as risk factors for the development of extraintestinal manifestations in Crohn's disease. Surgical treatment of the intestinal disease represents a therapeutic option for patients with extraintestinal manifestations, as it seems to prevent or delay these manifestations in most cases.

01:30Inflammatory 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, 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...
