Background:
Duodenal complications of necrotizing pancreatitis (NP) are challenging and understudied. We sought to characterize the demographics and clinical course of NP patients with duodenal complications.
Methods:
Single institution retrospective review of 687 NP patients treated from 2005 to 2018.
Results:
Duodenal complications developed in 40 (6%) patients including fistula in 11 (2%) and stricture in 29 (4%) patients. Patients with duodenal complications had increased computed tomography severity index (CTSI), degree of glandular necrosis, organ failure, infected necrosis, and disease duration. Mortality from NP was increased in patients with duodenal fistula (36%) compared to patients with duodenal stricture (7%) and patients without duodenal complications (9%). Surgical management of duodenal complications was required in 9/11 (82%) patients with fistula and 17/29 (59%) patients with stricture.
Conclusions:
Duodenal complications occurred in 6% of necrotizing pancreatitis patients. Sixty five percent of patients with duodenal complications required surgical correction. Duodenal fistula was associated with increased mortality.

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...
01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
