Background/Aims:
Von Hippel-Lindau disease is an autosomal dominant genetic disorder characterized by neoplasms developing in multiple organs. Although the pancreas is one of the most frequently involved organs, the frequency of pancreatic cysts, cystadenomas, neuroendocrine tumors and diabetes has not been sufficiently evaluated due to the low prevalence of this disease. In this paper, we review and retrospectively analyze 11 patients with von Hippel-Lindau disease.
Methodology:
Eleven patients (6 males, 5 females) who underwent CT or MRI scans at Okayama University Hospital between 2002 and 2009 were enrolled in this study. Their pancreatic CT scans, MRI scans, biochemical test results and clinical histories were retrospectively reviewed.
Results:
All patients had one or more pancreatic involvements. Nine of the 11 patients had multiple pancreatic cysts, 2 had dilatation of the main pancreatic duct, 3 had a non-functioning pancreatic endocrine tumor (one patient required pancreatoduodenectomy due to the endocrine carcinoma) and 3 had diabetes mellitus. Pancreatic cystadenomas were not detected in this case series.
Conclusions:
The prevalence of pancreatic involvement was 100% in this study. Regular screening and scheduled follow-up for pancreatic lesions and diabetes should be performed on individuals predisposed to von Hippel-Lindau disease.

When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
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:
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, 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...
