Background:
Intraductal papillary mucinous neoplasms (IPMNs) are the most common cystic tumors of the pancreas. They are usually incidental findings in asymptomatic individuals and have an uncertain natural history. In most cases, the diagnosis relies on imaging and may be supported by endoscopic ultrasound-guided cystic fluid sampling (and eventually other advanced EUS-based techniques).
Summary:
Determining which IPMNs require further investigation and follow-up involves identifying features associated with a higher risk of high-grade dysplasia or invasive cancer, which may ultimately require surgery. The clinical management of IPMNs remains challenging, placing an increasing burden on healthcare systems.
Key Messages:
A thorough understanding of this condition is essential to guide clinical decisions, optimize resource allocation, and improve patient care. In this review, the Portuguese Pancreatic Club summarizes the most recent literature regarding epidemiology, classification and natural history of IPMNs.

01:26Pancreatic Juice and Secretion
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...
