Abstract:
Disorders of the hepatobiliary system are commonly associated with gastrointestinal (GI) diseases. The GI and hepatobiliary systems interact through the portal vein system and enterohepatic circulation, creating a gut-liver axis that allows for a complex multidirectional interplay between immune, hormonal, dietary and environmental luminal factors that include the gut microbiota. This interaction may underlie the liver affection in autoimmune and immune-mediated small bowel diseases through a variety of pathways that include autoimmune, metabolic, immune-mediated, and/or iatrogenic mechanisms. Despite evidence of a gut-liver axis and co-morbid liver associations with small bowel diseases, the clinical implications and how these conditions should be clinically managed remain unclear. In this narrative review, we describe the hepato-biliary manifestations associated with chronic immune-mediated enteropathies of the small bowel in adults, with particular focus on CeD and Crohn's disease.

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...
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...

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...
