Background:
A 29-year-old man was admitted with a 7-day history of progressive non-specific abdominal pain that progressed to small bowel obstruction following ingestion of a 20-pence coin 4-months previously. Colonoscopic retrieval was unsuccessful. A subsequent laparotomy revealed a chronically inflamed thickened terminal ileum with mesenteric fat encroachment necessitating a right hemicolectomy. Histopathological analysis confirmed Crohn's disease with impaction of the 20-pence coin in a distal terminal ileum stricture near the ileo-caecal valve.
Learning Point:
Gastrointestinal foreign body retention should alert the clinician to the presence of an undiagnosed bowel abnormality. Furthermore, failed endoscopic retrieval should be considered as a marker for potential underlying gastrointestinal pathology and a requirement for operative intervention.
Conclusion:
This case describes a rare presentation of Crohn's disease and highlights the need to consider underlying gastrointestinal pathology in patients presenting with a deteriorating clinical condition in the presence of an incidental foreign body.

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 III: Diagnostic Studies and Management I-Nutritional Therapy
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 colonic...

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...
