Introduction:
Although cases of severe pancreatitis causing fistula formation into the colon have been documented, the reverse process of colitis causing a pancreatic fistula remains undocumented.
Case Presentation:
We present the case of a 79-year-old male with severe colitis resulting in perforation and pericolonic abscess formation adjacent to the pancreas, which resulted in an internal pancreatic fistula and pancreatic ascites. After 2 paracenteses, our patient ultimately underwent endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and pancreatic duct stent placement. The patient clinically improved and was ultimately discharged.
Conclusion:
Follow-up ERCP was performed 2 months after discharge and showed no contrast extravasation, illustrating closure of the previous pancreatic fistula. Ultimately, our case demonstrates that cases of severe colitis may contribute to adjacent pancreatic fistula and ascites formation.

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

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...
