Abstract:
To characterize the associations between clinical disease activity with endoscopic and histologic (endohistologic) mucosal healing in Crohn's disease, we performed a secondary analysis of prospectively collected data on 424 ileocolonoscopies from 258 unique adults at a tertiary referral center from 2014 to 2021. One-third of patients (34%, 25/73) in endoscopic-histologic remission reported gastrointestinal symptoms. The 2-item patient-reported outcome measure for abdominal pain and stool frequency correlated weakly with endoscopic (Simple Endoscopic Score for Crohn's Disease; r = 0.17, 95% CI 0.08-0.26, P = 0.0003) and histologic disease activity (Global Histologic Disease Activity Score; r = 0.14, 95% CI 0.03-0.24, P = 0.015). Overall, gastrointestinal symptoms correlate poorly with endohistologic disease activity.

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...

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...

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...
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...
