Abstract:
Endoscopic retrograde cholangiopancreatography (ERCP) plays an important diagnostic and potentially therapeutic role in the management of a broad range of biliary and pancreatic disorders. However, it is an invasive procedure with an associated complication rate in the vicinity of 5% to 15% and mortality rate of 1%. We present an unusual case of a patient who sustained a stent-related duodenal perforation after undergoing ERCP. We reviewed the current literature in regard to risk factors, etiology, diagnosis, management, and prognosis of ERCP-related perforations, aiming to provide a brief, updated overview of this devastating complication.

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...
