Objective:
In 10-15% of patients with colorectal inflammatory bowel disease it is not possible to determine whether they have Crohn's disease or ulcerative colitis and they are therefore classified as having inflammatory bowel disease unclassified (IBDU) (formerly referred to as "indeterminate colitis"). The aim of this study was to determine whether upper endoscopy with biopsies could be a useful tool for diagnosing patients with colorectal inflammatory disease.
Material And Methods:
Fifty-two patients (14 colorectal Crohn's disease, 19 ulcerative colitis, 6 IBDU, 8 microscopic colitis and 5 without IBD) were examined by upper endoscopy. Biopsies from gastric and duodenal mucosa were examined histologically and the frequency of focal cryptitides was estimated. Helicobacter pylori-positive patients were excluded.
Results:
Focal cryptitides (sometimes called focally enhanced gastritis) were found in 8/14 of patients with Crohn's disease, 4/19 patients with ulcerative colitis, 2/6 patients with IBDU, 2/8 of patients with microscopic colitis and in 2/5 patients without IBD.
Conclusions:
Focal cryptitides are more commonly found in gastric and/or duodenal mucosa in patients with colorectal Crohn's disease than in other patients. Upper endoscopy with mucosal biopsies contributes towards a diagnosis in patients with colitis.

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 transmural...
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...
